    4.5/5,
    Pros - Excellent build.
    Multi-usage ability.
    Sound of which benefits audio and gamers.
    Powerful enough for most headphones.
    Cons - Can get a bit warm (but taken care of in a PC with a fan.
    Low-level noise with sensitive IEM's.
    No balanced out (but not unlike it's peers).
    Not much else.
    Burson Play Classic (with Vivid Op-Amps included)- $549 https://www.bursonaudio.com/products/play/ 5-year warranty.



    There has been a lot of fuss surrounding the Play. Released several months ago, the Head-Fi thread is still very much alive and kicking (https://www.head-fi.org/threads/new-burson-audio-play-amp-dac-2w-16ohm-op-amp-rollers-dream.860882/). I will admit, I do not know much about Op-Amp rolling, but from what I have read, it is another way that manufacturers can “fine tune” the sound of their wares. This can be done readily by the user and can run from inexpensive to QUITE expensive. As this unit has moved through several hands, Burson included the single Op-Amp Vivid module as well as the included Classic modules. You can go “as low” as $299 for the basic model, and purchase the modules separately, or opt for the higher line Classic or Vivid. From my readings, the Classic is tuned more towards a bass-oriented sound, with natural sound (and I concur). The Vivid provides a more “lively” analytical sound for those who wish that. Coming with a 5-year warranty says something about the confidence Burson has in their product. Good for them.


    Burson Audio, an Australian company, is known for making very good amps. The Soloist and Conductor are two that have sold very, very well. With the Play, the company went a slightly different route. One can certainly plug-and-play (pun intended), but for those who wish to fine tune, that is where the different Op-Amps come in. Something that many audiophiles are turning to. Personality of their own gear. I’m in, for the first time.


    I will thusly admit that I was looking forward to rolling amps. This is a nice alternative to changing cables, or tip rolling; which allows the user to personalize or fine-tune to their desired sound. What I can say is that right now through my MacBook Pro using the Simgot EM5, on Damian Marley’s Here We Go, there is more than enough bass to satisfy me. I am not a basshead but do enjoy a nice rumble with my sound. I do like what the Burson has provided so far.

    Unboxing/Finish:

    Since this was a tour unit, there was already some wear and tear on the box. That said, the innards were well protected using foam all around and the two accessories boxes on the sides. Included was the amp itself, a power cord (with AC/DC adapter), remote, Vivid Op-Amps (and tool used to open the chassis), dual RCA into single RCA cable for use as a Pre-Amp, a 6.3mm to 3.5mm jack adapter, a standard USB to USB (?) cable for connection to your source, and the necessary cable to use within your PC tower (and a different back plate for use in PC). Touted for gaming, the Play has been received well in the gaming community for its clarity and detail. Something necessary for active games and role-playing games.

    [​IMG]

    Since I do not have a PC, I will focus upon the Classic and Vivid Op-Amps and connection to my devices. That said, the vast majority of my time was spent hooked to my MBP, utilizing several different IEM’s and the Focal Elear.


    The build quality of the Play is as expected, top notch. A basic black box, with a welcome digital volume readout on the front as well as a rotating volume knob (not the most accurate if you spin fast), a microphone jack (for headphones with mics), and 6.3mm jack. The back (L to R) has the USB jack for connecting to your source, power plug, an on/off red toggle switch, and the RCA L/R channel connection. Not much there, but with the innards as the main course one need not worry about different connectivity. Sitting innocuously on one’s desk, it could be almost overlooked as a time piece, or external hard drive. And, I do like the understated nature of that plain black box. This is not one for flash.


    I will state that on this copy, the volume knob does not represent one-click per number. I often find raising or lowering the knob one at a time will result in the number jumping up/down the desired amount, then returning one number up/down. I don’t think the calibration of the knob/digital readout is precise enough. That said, is may well be that this unit has gone through several hands and most likely hundreds of hours. That could be the case as well.

    Sound:

    I will admit that for the vast majority of time, I had the Classic Op-Amps in. I enjoyed the bass note, which the Classic provided. Still with good detail, Damian Marley’s Medication sounded just as it should. Bass line to die for, cymbal detail of almost hissing quality (a good thing here…) and vocals, which were clear and prominent. This was becoming a nice treat from the get go. This was not some shout in your face look what I can do amp. No, this was a well-played laid-back sound, which grew on me. That is part of the reason I am having a very hard time putting into words what I heard and felt. It just played, providing a solid enjoyable sound.

    I must say that while any IEM I plugged into the Play sounded quite good, enhancing their respective sound, it wasn’t until I hooked my Elear in that the Burson showed its true worth and value. Harder to drive than most of my headphones, the Elear was taken to 35 (from 20-25) on the Burson in order to get the near-same volume of the IEM’s. In doing so, the Play did not start to shout at me, no it delivered a crisp, full, detailed sound worthy of inclusion in any conversation regarding the Elear. It was good, very good. Decent-enough bass to keep me interested, as well as mids, which complimented both ends without taking front and center. Vocal sound, which while not the best I have heard from “portable” amps (I do like my Black Label), certainly entertaining enough to make you appreciate what Burson has done to make an affordable desktop amp. Especially when you start comparing the Play to more expensive amps. Several reviews noted that the Play could easily be put into a conversation when talking about amps twice the price. I do think it can hold its own in that conversation.

    When one purchases such an amp as the Burson Play, half the fun is the tuning ability, which can be provided. Going from the Basic $299 model to all manners of this version at $549, you can fine tune with the Op Amp rolling. Unfortunately, I am not the best in which to decipher the finer points, so I will leave that to those with more expertise as in on the Burson Play thread, which still keeps going. I am simply not the best judge of that and will analyze from the amp stage only.

    Not having the Burson hooked up, due to vacation callings, I returned with anticipation at finishing this review. One does need dedicated space for such an endeavor and that was not conducive to traveling. But, a high point in selling the Play is its ability to be utilized in a desktop computer, using one of the 5 ¼” slots. Almost a novelty of a bygone era to me. Touted as a gaming amp for its accuracy, I can only recommend that the Play is indeed true of sound, with excellent instrumentation and separation.

    While providing me with that warmer sound of which I love, the detailed separation is not lost in that aspect. Touted in the gaming community for good reason, it is. With the detail of Mark Knopfler’s drummer in Laughs And Jokes And Drinks And Smokes, it is clear to the point of almost hearing the air movement of drum stick. I exaggerate a bit, but it is quite nice. On par with my iFi Black Label, which coincidentally falls into the same price point. I would point out that the Burson has decent enough treble for the audio enthusiast and gamer as well.

    Succinct, and accurate is what I would call that treble. Pleasant to my treble-sensitive ears. Want more? Switch to the Vivid Op Amp and you have it. Many a better ear than mine have espoused the virtues of the Vivid modules, and with what I could hear, I would agree. Changing is easy, except if you use the Play within your computer. That “lack of treble” to me in the Classic mode is all but thrown aside though, when Corazon Espinado comes through the Elear from Santana. Superb male vocals highlight the song, with Carlo’s sumptuous guitar emanating from one’s ear. The support drum instrumentation providing that push up top to very acceptable levels in my mind. Just a superb rendition of a voluptuous song. The Elear approve.

    [​IMG]

    Follow that with See Dem Fake Leaders from Ziggy, and the bass line draws you completely in, while the supporting horn line prods at your ear for full attention of the important message purveyed. Ziggy’s vocal harmony is the icing on the cake, and I can say that the Play is about as good as any amp in which I have listened at this price point. Versatile I would call it.

    Alpha & Omega from Jah Shaka sounds full, inviting, almost decadent in its hidden trippy sound. The Burson allows that trippiness to “play” through unimpeded, giving full meaning to the song. Follow that with Heathens from a perennial favorite of mine twenty one pilots, and you complete that trip ‘round the Play. I could auto-repeat those two songs happily for hours. And the Play would be a good companion in that pursuit of musical bliss.

    Comparo/Pairings:

    Close on the heels of the above paragraph, Van Morrison belting out Take It Easy Baby beckons me into that Jazzy haunt of a basement dive, wrought with drink and companionship. This is a sound, which escorts very well with whatever thrown its way. I will state again, that the Elear rose quickly to the head of the class in use as most of the IEM’s thrown its way were simply not at their best.

    As stated The Elear/Play combo yielded a full robust if slightly warm sound emanating from within. As that is my preferred sig, I did not mind. From day one of my auditioning the Elear, I knew it was the open headphone for me. And as luck would have it, when the Clear came about, many jumped on that bandwagon singing that this is what the Elear should have been!! Well, not to diss any of them, but I call bunk. The Elear is an extraordinary example of a high-end headphone at “affordable” prices. Those who jumped ship to the Clear do have that right, but I say good riddance. The Elear/Play combo simply fortified my belief in the above. And I was glad. Running Tidal through my MBP, the sound was rich, vibrant and full. With enough detail (MBP after all…) to keep me interested, this was a worthy addition to my desktop sound.

    Moving to the “portable” aspect, I hooked my Opus #2 up and gave a listen. Providing more detail than a MBP could ever provide, I streamed Tidal with even better results. What the MBP lacks in upper end, the #2 provided. Still utilizing the Elear/Play, I was quite happy with the result. Almost thinking, OK…how could one make the Play a portable option?...The Opus provided the air between notes, which the MBP could not. From that added detail, came more clarity and paired separation of instruments. While not my perfect set up with the Play, it was a very pleasing set up, which as mentioned yielded the most detail. Quite acceptable, indeed.

    Harkening back to the IEM-mode, I switched to the UM Mason V3/Mentor V3 pair I had on hand. Immediately I was met with some hiss (and if I can hear it, well then…) during pause. But, once the song started, there was no hiss. And as others have mentioned those with high impedance may face the same. But, as I said once the song started, the bliss returned. The V3 iterations are a true marvel, and a worthy step up from the V2, to which I have espoused every review. But, while the Mason/Mentor sounded quite good, there was to me a slight miss here. The Mentor still had that deep reach of bass, that the Mason lack in my opinion, but the sound was just not as satisfying to me. That said, take the Play out of the equation, and run a side-by-side of the Elear/Mason/Mentor through the #2, and there is that sumptuous quality of both again. As some have mentioned, some items simply do not pair with others. Take that as a “*” because the sound was still very acceptable to me, but behind the Elear.

    Running the Kinera iDun through my Shanling M3s and the Play raised both up a “level.” While the pair without the Play is quite a stunning pair of their own merit, here the Play raised the “qualities,” which make each good. Better detail was again wrought through the iDun, which has pretty decent detail with which to start. And as we know, the Shanling provides that warmer sound from the get-go. So, again the Play made the items plugged into each end “better.” Or maybe a more apt description would be “raised.”

    [​IMG]

    Finale et al:

    So…what is one left with when considering the Burson Play? For those who would like an affordable desktop/PC-worthy amp you can start with the Basic ($299) or v5(i) for $475/399. Then as needed, add the OP-AMP of choice. With the one on hand, we are lucky enough to have the Vivid modules and the Classic; and it was a treat.

    At that Basic-level price of $299, you are faced with the iFi xDSD in the portable realm as well as some others. While the xDSD retails for $399, and comes with more features, you can get the Play knowing you are getting a desktop amp, with the options to add modules later. That would of course bring you in line with the iFi price. A hard choice, whether to go portable with more features or simple and desktop worthy with that future upgrading capability. To me, they occupy two different realms, so it would be easy to get both.

    When we move upscale as this one is, then the comparison falls to the iFi Micro iDSD Black Label ($599) in my mind (plus I own one). With many more tuning options for sensitive headphones, and MOAR POWER; one must balance that against what you get with the Play. I call the BL transportable as it is quite large to take with you often. As such, it stays quietly on my desktop awaiting use. Here is where the decision would be again whether you want future upgrading (and in the same price) or immediate tunability without much loss in sound. I will state that for “pure sound,” the Play is a smidge ahead. But for fine tuning the sound, the BL is well ahead, and easier to modify on the fly.

    For the dedicated gamer, the Play would be an exceptional upgrade to their existing PC, short of those who have spent several thousand dollars. Add to that the “reality” of sound and placement some have mentioned (and in personal convos with others recently), and that was enough to sell them on the virtue of adding the Play to their gaming-unit. A nice two-fold win for Burson in that regard. Add in that while Op-Amp tuning is great, once a gamer settles on their preferred sound, the Play will most likely stay inbound on the PC and you have a very worthy addition to existing computers, which pretty much blow out of the water the existing DAC/amp in most. Again, a great marketing tool for Burson.

    So, it comes down to what exactly are you looking for in an amp. Will this be a long-term relationship, where one can upgrade to new OP-AMPs or portability? This is the real draw of the Play to me. You can start with a very good amp, and upgrade when funds become available. OR, opt immediately for the higher priced model and be quite satisfied. The Burson is a very good amp with which one could easily listen and own for a good long time, without being drawn into something “new and glittery.” And after all, isn’t good quality sound what we are after in a long-term relationship, anyway?

    I want to thank Burson for my extended time and listen. Without that extended time, I would not have been able to compare to some incoming gear, which aided my overall evaluation. And, they should be very proud of what the Play can achieve. Excellent sound at either end…the entry price or full-blown desktop amp. You can’t go wrong either way.

    My Impressions
    Written by alighill
    Published Apr 14, 2018
    5.0/5,
    I listened to 3 songs on AK120, Burson Play IC and Burson Play V6C, and recorded my impressions below.

    Linkin Park - Hands Held High

    ak120 - this dev ice had a lot of clarity, especially in the richer tones of bells and violins, and the snare felt very distinct.

    Burson Play IC- the music seemed a bit duller, but the vocals were more prominent. overall, the music seemed to blend a bit more, with the vocals out in front.

    Burson Play V6C - This was a wonderful listening experience. the tones merged together without overpowering each other, the organ and bass were as clear and distinctive as the violins and the drums while complementing them in perfect harmony. made me think of the first time i listened to this album.

    Won't Back Down - Eminem ft. P!nk

    ak120 - Once again, this device was able to show a lot of clarity in the treble ranges. it was a little less effective in the bass, but the overall effect was good.

    Burson Play IC - the listening experience for this track was better then the first one, however, it would appear to mostly have to do with the increase in bass used, as this device seems to have a greater ability to convey good bass than anything else.

    Burson Play V6C - once again, this was the best listening experience of the 3. you could believe you were in the room with the instruments, not listening to a recording. instruments are distinct and well defined.

    If my heart was a house - Owl City

    AK120 - great listening experience. clear sound.

    Burson Play IC - overall, this was the best of the 3 listening experiences with this device, but still did not compare to the others overall. the sound quality was good, and this particular song felt great, but just lacked that extra little something.

    Burson Play V6C - this felt like magic. the clarity was goosebump inducing, and highly enjoyable.

    Review Of Burson Play
    Reviewed by Mike Brunner – Lead Guitarist of RĪvul

    Purpose of this review

    I’m a gigging musician (lead guitar/backup vocals), a forensic audio analyst, a wireless communications technician, a novice sound engineer, and an avid music lover with a wide taste in music. Being a forensic audio analyst is a plus when reviewing audio products simply because I know what bad audio sounds like and usually know how to correct it. My experience allows me to be familiar with the limitations of my own ears and the equipment I’m using.

    My perspective for all my reviews is based on these things. I don’t try to sugar coat things or bloat things to be better than they are. I’m just like everyone else and I want good value for the money in any product.

    I’m fair to the manufacturers as well. I always give them an option to respond to any concerns such as quality that I have during my review. I contact them directly and do so before my review is published to allow them to address any issues. I want to provide an honest and tangible review for prospective customers without being unfair.

    The Burson Play was provided to me free of charge for the purpose of this review by @Barra and Burson and will be returned upon completing my review.

    Now on to the good stuff.

    Build/Design
    The Burson Play is a very sturdy build, with a metal casing. The versatility of the design is that it can be mounted either on the desktop or mounted in the case in any PC computer case with front mount openings. This versatility allows for a wide range of usage scenarios. The LED level indicator is bright and fully visible on the front of the unit. The digital volume knob large and very responsive.

    The overall build and design of the unit is well above average. Simple and effective.

    Sound
    The real good stuff! This is what all of us audio geeks/audiophiles want to hear about. So when I first started this I decided to give myself a baseline using my pro audio gear. I first listened to my desktop DAW interface (Sapphire 2i4) and Midas M32. Both are designed to give pristine audio with no coloration at all. My monitors of choice this time were my 64Audio A18t and InEarz Euphoria. The 64Audio pairing is for technical listening with musicality, whereas the InEarz is for ease of listening.

    After setting up the baseline through listening to each interface for an hour the break down was the Burson Play is a very clean DAC/Amp. There was little to no noticeable difference to my ears. After listening to the Burson Play the transition back to my pro audio sources were nearly transparent.

    Across the entire audio spectrum the Burson Play seemed very flat. I actually hooked both the headphone out and the RCA outputs to my DAW to analyze the frequency response. In the lowest frequencies, the Burson Play showed a slight dip below 20Hz, and a slight dip above 20KHz. This simply put, in the audio range, the Burson Play showed a perfectly flat frequency response. Whatever you put in you get out. Near perfection for $299? Wow! Comparable to the output of a $4000 pro audio mixer? I was very surprised at this. Even though on the frequency analyzer I saw no issues, I did notice that the soundstage didn't seem quite as wide as my pro audio interfaces. There was no cross talk between the channels and after about 10 minutes of switching to the Burson it wasn't noticeable, after a quick switch, the staging was just slightly narrower.

    Real world application/Features
    I used the Burson Play for approximately 2 weeks as a DAC using the RCA output into my Midas mixer for playing music, practicing guitar and for playback. It never once had any issues and the audio remained crystal clear. Although for my usage I would like to have seen an input for my guitar, I see no issues for the average audio enthusiast.

    Value
    When trying to gauge value in any product I look at many areas, build quality, performance in real world situations and any shortcomings. As for shortcomings I saw no issues other than I would have liked the sound stage stereo width to be a little wider and an analog input for my usage would've been nice.

    All together the Burson Play was great DAC/Amp. It had no problems powering and I noticed no coloration to my IEM's. Outstanding product and value, a definite upgrade to normal computer audio and near perfect audio frequency reproduction.

    Good job Burson.

    Review of the Base SKU of the Burson Play.
    Written by rvcjew
    Published Nov 24, 2018
    4.5/5,
    Pros - Packaged very well during shipping.

    Good Power on the amp side. Clean sound.

    Good USB Chipset.

    Comes with everything needed for case mounting including the RCA bracket for expansion slot and the internal USB header.

    Simple design with only an LED face, quarter jack headphone output, 3.5mm mic input and volume knob with push to mute. All power and input hookups in the back.

    Sound can be changed to how you prefer with any compatible opp-amps.

    Does not distort at higher volumes.
    Cons - IEM usage has slight hiss on the noise floor.

    No kind of gain adjustment.

    No S/PDIF in, only USB. Con for some.

    Next revision should use a SATA VS MOLEX power connector IMO.
    I'v purchased some Burson products in the past and so they offered to let me evaluate the Burson Play in its lowest stock form. I naturally took the opportunity as I'm very happy with their opp-amps in my current setups. I initially heard they were a good upgrade to the Xonar Essence STX so I picked up some V5 Dual's and was blown away how it sounded compared to the stock JRC2114. After that I got the XD-05 for portable use that I am happy with using a V5i Dual in it vs the Ti OPA1612 it came with. I also have the 2015 version NFB-11 with USB 32v2 and the TXO upgrades. I put the Play against all of these in it's stock form.

    First the specs:
    [​IMG]

    Second the Packaging, Accessories, Build and Looks:
    [​IMG]



    It comes with a tool to open it (I just used my own driver with a H2.5 for the front face and a T9 for the back), some very nice looking and feeling RCA cables, a USB cable for desk use, a USB cable for PC case use that terminates into a USB 2.0 header to go straight into the motherboard, and a bracket for the PC expansion slot that is a pass through of the RCA to the inside of the case and unit.
    [​IMG]
    [​IMG]
    Build:
    It feels very solidly built with only 4 screws (2x front/2x back) that need to come out to make changes to the opp-amps in it. It uses a hook and slot shape on the top cover so that it can only fit one way on the unit and stay secure on the sides. nothing feels loose on the outside.
    [​IMG]
    [​IMG]
    [​IMG]
    Looks wise it is very subtle with a clean face that is all black when off and when on only shows the volume level in blue LED numbers. The sides have a slight slight indentation of lines to break up some the flat look. The sides also have 4 holes for mounting within a 5.25" bay. The back has a USB B, RCA preouts, large power switch, a barrel connector for desk power and a MOLEX connector for PC power use which I really think should be SATA as not many devices use MOLEX besides some pumps nowadays. The bottom has four rubber feet that you could remove for case use if needed.

    Usability:

    Desk use: It is a very nice size for a desk as it is the size of a standard optical drive. You only need to have the USB and and power from the included adapter rated for 12V-6A which are both in the back for good cable management.

    [​IMG]
    Internal Use: It just mounts like any 5.25" device then you power it with a PSU MOLEX connector and use the USB B to USB 2.0 Header cable to plug it directly into your Motherboard. If you will be using the preouts then you will need to also install the rear slot pass-though bracket and plug that into the RCA's on the back of the unit. You want to mount it where it gets good airflow as it will get as hot or hotter then a HDD.

    The volume wheel is a infinite spinning digital wheel that can also be pushed for mute.

    Driver Setup:
    For a Windows machine you only need to use the driver from there support site (https://www.bursonaudio.com/downloads/). Once you have that you can turn on and setup the device in your playback devices appropriately. I used 24Bit 44.1Hz for all my OS testing and for music it was WASAPI in Jriver MC 24 with no DSP's.


    Sound:

    Stock: While Stock compared to my NFB-11 which is pretty wide in sound-stage and slightly bright I would say the Play is narrow (a good thing for gamers) and neutral making imaging excellent. If you are a gamer and want to do some serious FPS gaming and want to hear just footsteps ect, it will work very well. The Play is just as detailed as the NFB-11 as well.

    [​IMG]
    [​IMG] [​IMG] [​IMG]
    Opp-amp Rolling: This is one of the key features of the Play in my opinion because if you have either Bursons or another companies opp-amps in an older unit already and just want a solid hardware platform to switch to and experiment with the implementation of the XMOS chip in this one is very OS friendly.

    Power: While having no gain control I would say all my current headphones (M50, PortaPro, K7XX, TH-X00, M1060) are pretty easy to drive but it still has plenty of room to spare for some higher impedance ones. I mostly spend on the 10 mark and 16 mark if the AC is on. This is out of 99. It does not distort at the higher volumes either and seems clean in the whole range.

    IEMs:
    My IE80 is my only go to IEM for use today but it and my M300s have a small bit of static on the noise floor of this amp so I would expect all lower impedance ones would. This can probably be minimized depending on the opp-amps used in the unit but I was asked to review it stock so that's what I heard. Even with the louder noise floor it was still clear though at all volume levels.

    Since Black Friday I snagged some AF180's will will update on whether those have the same noise floor or not when I test them.

    Overall The product is excellent and I have not had any short comings with it and it's trick to be in a case is going to be be a must for some specific people and a great desk combo regardless that has that Burson build and quality sound.

    I again would like to thank Burson for letting me evaluate a part of there market I did not even realize they were in.

    Burson Play Basic - I love this thing!
    Written by Fasterball
    Published Oct 12, 2018
    5.0/5,
    Pros - Mic Input, Build Quality, Burson Customer Support, Unrivaled Sound in its Price Range, clear and fast sound, Op-amp rolling, Digital Volume Display, Big Volume Adjustment Knob, Phenomenal Sound Stage, tons of power (easily drives everything I have)
    Cons - drivers, no ability to pair a different dac with it
    This is the first review I have ever attempted to submit. I'm a fledgling audiophile - I'm still working on the ability to hear and describe all the things I'm hearing like you folks often articulate so well. I love great sound and believe I can appreciate the subtle nuances I hear between different dac/amp offerings. I'm coming from the quintessential Schiit Stack and the Audioquest Dragonfly Red - my sense is that the "Burson Play" outclasses both of these dac/amp offerings. [​IMG]

    Some Stumbles at the Starting Line

    I ordered the Burson Play directly from Burson Audio online. I almost immediately received a "thank you for your purchase" email but I did not receive any information about when shipping would occur. I didn't even receive an invoice number or purchase order number. The only thing I had to even reference my order was the paypal transaction number but that was provided by paypal. It wasn't until 3-4 days later that I received an email from Burson regarding shipping and tracking info. Once that hiccup was out of the way, shipping was relatively quick despite the fact my shipment was dispatched from Hong Kong. It was shipped on September 29th and arrived on October 09th. Dang Amazon has me getting impatient on any package I have coming my way. I feel it necessary to note here that Burson's early lack of communication was not at all indicative of their overall customer service. It was, as the heading states, just a stumble.

    Once my package arrived I was impressed by the clean-all aluminum-industrial look of the device. I know Burson designed this device to be placed in a standard drive bay of a computer but it looks really great out on the desk. Some folks have complained about the heat this device puts out. I have been running it now for 24 hours straight (I'm listening to it as I type this) and it feels no warmer than the Magni 2 I have after a few hours of use. That being said, I am a freak about my pc temps and I would not want this extra heat inside of my pc. That's especially true since it looks so good out of the case.

    Another stumble was the shear lack of documentation that came with the device. So many cords come with the device but only 2 are pertinent to setting up the device if you have it outside of the case and that is the USB cord and the power cord. The remainder of the cords are utilized when you install it inside of the case. There are no instructions explaining how to go about installing the device inside of a pc case. There is nothing to let you know that a driver is needed for the device to work as it should. When you go to their website they suggest that there are two drivers you need for windows 10. I learned from Burson that for the play I only needed the xmos driver. This was after several hours trying to install the cmedia usb 2.0 driver. Windows 10 seems to have its own xmos driver now but at the time of typing this it was still having issues and device manager would say the device did not have a driver so I decided to use the driver provided by Burson. As I was figuring this all out Burson's customer service was on point. They were quickly returning my emails and answering my questions as I was struggling to learn how best to set it all up. I think much of our back and forth exchange could have been limited if Burson included some instructions or even a card saying go to this website for a manual.

    The last gripe I have or stumble is the included usb cord is impossibly short. I have mine currently sitting on top of my pc chassis because it will not reach my desktop. Now granted this would be a none issue if my pc was on my desktop but it sits under my desk so the shortness of the included cable was painfully apparent. It would be nice if they could include a slightly longer USB cable.

    Setup Complete - How's it sound?

    For the Play Basic Burson recommends a burn-in period of 50 hours. This burn-in period is very important to accomplish prior to resting on any final decision about the Play. When I first got it set up and started jamming out to music and watching youtube videos I was fatigued by the harshness of the slippery S sounds. The device was sibilant and very bright by my estimation right out of the gate. It didn't help that I was listening with a pair of headphones that had a cable made from canare quadstar cable that is on the bright side. This sibilance and brightness became more subdued after the burn-in period was complete. The Play warmed up nicely, more bass came out of it then was previously there. Even after the burn-in period it remained on the bright side but it wasn't as in your face about it as it was before. I have really enjoyed the combo of my rather dark Audioquest Nighthawks and the Burson Play. I feel like they complement each other really well although the Play has way more juice than is needed by the Nighthawks. I routinely listen with the volume level at 15 with these headphones.

    The headphones I used to test the Play out are as follows: Audioquest Nighthawks, AKG K712 Pro, Hifiman HE 400i, and Audio Technica AD900X.

    The playlist I used to evaluate the Play is as follows: Riding for a Fall by Chris Ledoux, Thunder Rolls by Garth Brooks, Hotel California by the Eagles, Bubbles by Yosi Horikawa, Mr. Bojangles by Nitty Gritty Dirt Band, Dragonborn by Jeremy Soule, Forgot about Dre by Dr. Dre, In the Air Tonight by Phil Collins, Hallelujah by Pentatonic, and The Master's Call by Marty Robbins.

    The thing that stood out to me the most in running through the above playlist with each of my headphones is how the sound seemed livelier, more energetic, and faster than when I listened to it on the modi/magni and dragonfly red. I'm not sure what accounts for this but the music was more engaging and for me fun to listen to. The drum riff in In the Air Tonight dang near got me up out of my seat with a "hell yeah" it was so awesome.

    The sound stage on the Play is unreal. I included some songs in my playlist just to test the sound stage. Yosi Horikawa's Bubbles was so cool to listen to. With the clarity and sound stage the Play offers I felt like little balls were bouncing all around my head. At one point I even turned to look, slightly freaked out by how real the directional audio felt. Gamers will love the Play for the mic input as well as the solid directional audio that can be experienced while using it. The Master's Call sounded awesome too as the recording has the back up vocals coming from one direction and the instruments coming from another with Marty Robbins coming at you from the center. I felt transported to the Opry Stage as I listened to this track.

    The mids and highs are clear and detailed and after burn-in, not overemphasized. The bass is a little lacking but becomes more apparent after burn-in. Listening to my playlist with my HE400i's, the planar magic really shines through as the amp supplies really clean and effortless power to them. I love how that planar bass sounds so smooth on the Play despite not having the greatest sub bass extension.

    The included mic input pairs really well with my Mod Mic. Previously I've had to enable onboard audio or use a cheap usb dongle with mic input to use my Mod Mic. This is no longer the case as my high quality amp/dac is now also my mic input. I love this feature. I love that I can have audiophile grade sound quality with a class A amp and my mic input all in one place. It makes my mic sound so much better than before as well! The Play has it all for a gamers and music lovers alike.

    [​IMG]

    Conclusion

    I love this device! This is my end game... for now... lol! To me it's beats out the Schiit stack and the Dragonfly Red. I know at $299 the Play comes in at about $100 more than these two options, but it's really not even close in my mind. To me it is absolutely worth the extra $100 in sound quality alone but then when you throw in the mic input and the clarity it gives your voice then the raw value here becomes clear. I am excited about the prospect of opamp rolling. I'm satisfied for now but I know the upgrade bug will surely hit me soon and when it does instead of buying new hardware I can buy some opamps.

    Burson Play review
    Written by icsterm
    Published Sep 3, 2018
    4.5/5,
    Pros - Fast, clear and articulate Sound

    Spread out and out of your head experience

    Tons of power, watch your volume settings

    Great build quality and simple industrial design
    Cons - Would like a line-in as well to use it as a separate headphone amp
    I borrowed a Burson Play from one of my friends and was quite impressed by it that I decided to do a dedicated review for it.

    First of all this is my first contact with Burson Audio gear, I never listened to any of their upper class stuff but this little fella is looking really good.

    I’m coming from smaller DAC/Amps made by FiiO so for me Play seems in completely another league.


    [​IMG]

    I really like its very simple look and design, its almost industrial looking.

    I also like that it is a whole package as a DAC and a headphone amp, you just plug your headphones are you are done, you need nothing more.


    Looking at specs I really was impressed by the power ratings and finally this is my first time listening to an ESS Sabre DAC chip.


    I am using it for about 2 weeks now with my laptop running Tidal Hi-Fi, driving a pair of Sennheiser HD660S.


    [​IMG]


    Now lets cut to the chase shall we?


    Well, so far I listened to my HD660S only from lower tier DAC/Amps so this is really my first contact with a higher quality stuff and the difference is quite big.

    I know HD660S is not top of the line, but nor the Burson Play is that.

    However there is a really big difference between my FiiO E10K and Burson Play.


    Everything sound clearer, I hear more nuances in my favorite songs.

    Like little new notes that I never thought were there I am hearing them for the first time.

    [​IMG]


    Besides that there is A LOT MORE power on tap compared to my small E10K.

    I mean there is no contest; Play just smashed the E10K on every aspect.

    If on E10K I am going almost full volume to hear better dynamics and impact, on Burson Play I cannot go higher than 30 out of 99! It is very powerful indeed.


    Rock music sound punchier and somehow faster, its like I upgraded my HD660S to some Audeze planars or something like that. Listening to electronica is also enlightening, a really amazing experience.


    [​IMG]


    Overall Burson Play has this kind of bold and big sound, hard to explain. The sounds are almost outside of your head and not inside it. Some people call it soundstage however its hard to tell there is something like that on headphones as well.

    Its first time I hear a 3D sound effect on regular DAC/Amps, I checked again all the specs but I don’t see any gaming DSP or something like that, its just Burson Play by default sounds like that. Especially on very well recorded music everything sound crystal clean and spread out, almost like a 3D sound recording.


    Out of curiosity I played some binaural recordings and I felt like I am tripping, wow, such an amazing experience.


    What can I say Burson Play really impressed my not only by its technical specs and build quality, but especially but it bold and big sound.

    I always felt like I was using a super-car when listening to Play.

    Everything is faster, hits harder to a point you feel you might damage your hearing…


    I left impressed and too bad I should give it back to its original owner, I am already thinking if it is worth buying one and I think it is. Definitely worth it, who I am kidding as I am saving for one already.

    Looking forward on trying the Fun in the next weeks.

      PLAY has no volume control for its internal amplifier, the volume knob only adjusts internal DAC's volume. Not sure a Line-In would help much here, unless you want to use its internal 2.5X-gain amplifier as a "PA" (around 5V RMS) or add an external pre-amplifier to control the output volume. I think FUN would more appropriate to be used with an external DAC, as FUN has dedicated volume adjust control.

    HL: Burson Play DAC/Amp vs. ES9038P + FUN01 XMOS
    Written by NCSUZoSo
    Published Aug 5, 2018
    5.0/5,
    Pros - Ability to upgrade at a later time to a higher end rig.
    High mobility/portability due to a very compact design.
    Entire chassis acts as a heat sink and entire chassis is grounded.
    Excellent quality audio for the cost. The Play is able to compete with ES9038PRO DAC and even win a few of the tests.
    Plenty of power using the internal amp, powered by two single-DIP op-amps.
    Ability to slide the Play right into a PC 5.75″ drive bay.
    Ability to listen to RCA and headphones outputs simultaneously.
    Uses I2S to communicate with XMOS.
    Can be powered a variety of ways.
    Has a remote and a few other included accessories, sounds small, but an important detail.
    Cons - Can get fairly warm, but these are the realities of a Class A amplifier and the components can handle it.
    Not as good at rejecting noise as the ES9038PRO DAC can. The FUN01 also plays a role in the cleaner signal. (Note: this opinion is after fixing the USB ground issue.)
    Unable to get a Play that uses the Amanero, although you can easily get one that fits if you want one, just not stock.
    The Play’s display could give us more info and the inclusion of a simple menu would be nice. Just give us a few filter selections and a few other basics menu options (as seen on the ES9038P’s screen).
    There can be a digital noise issue because of the fact there are two paths to ground in the Play if you leave the USB cable’s GND connected. I disconnected mine as advised on Head-Fi and the digital noise stopped. Still have to list this as a con though, the average consumer might not want to cut into a USB cable or de-solder something.
    Hallman Labs©: Burson Audio's Play DAC/Amp vs. ES9038P + FUN01 (Singxer SU-1 Clone | XMOS)

    At the request of Burson Audio I am sharing my latest review to date. This is between the stout Burson Play w/ 5x V6 Classics and the ESS ES903Pro w/ 4x Sparkos Labs SS3601/SS3602 and the FUN01, a clone of the Singxer SU-1 without the power supply part. I up the ante even more when I came back to add Black Gate™ "F" capacitors all around on the FUN01. This heightened the clarity of the FUN01 even further than before, after a few weeks of burning in. Nothing in this review was rushed and I tried to verify what I heard more than once before sharing it. I wasn't paid to do this review, but I was provided review hardware.

    [​IMG]

    My review today is focused on Burson Audio’s “Play”, a potent DAC/Amp combo available in a variety of prices. Dependent on the op-amps chosen from Burson Audio, the price varies from $299 (no remote) up to $549 (with 5x discrete V6-OPA “Classic” op-amps + remote, the setup shown in this review)! The Play uses an XMOS chipset for USB/digital audio in and it has a full pre-amp and headphone amp, offering both ¼” and RCA outputs. You can run the ¼” output and the RCA output together/at the same time. This is similiar to how the ES9038P can do XLR and RCA out at the same time from one pre-amp.


    [​IMG]

    I confirmed with Alex at Burson that the XMOS unit talks to the main DAC using I2S! This is why you are able to play DSD128 with ease on foobar2000! The 64-pin ES9018K2M seen on the primary PCB (under the XMOS unit) is responsible for converting this I2S into analog wave-forms. We have a ton of different op-amp sockets to “Play” with (5 in total), yet it will still fit into a CD/DVD 5.75” drive bay in a PC case. I will be using the V6-OPA “Classic” line from Burson across the board inside the Play for this review. Burson Audio includes a standard 12V Molex power connection on the rear of the unit as well as a microphone input on the front. The 12V Molex connector allows for an easy power connection when the Play is inside your PC’s 5.75” drive bay. All of these features come together to give you the whole package in one very mobile footprint!

    [​IMG]

    The microphone is powered by a small C-Media HS100B (thanks to Head-Fi.org for this correction). After connecting USB, most computers will see the ES9018 output and list it as a generic USB device. This ES9018 output is not meant to be used, so disable it. If you don’t choose the XMOS device (default) named “XMOS-XS1-U8 MFA (ST)”, you’ll never get any sound output. You can find the XMOS driver for the Play directly on Burson Audio’s website in the download section (found here https://drive.google.com/file/d/1RwVLfyNDo0u79erR3KaETreUnlemVhjn/view).

    [​IMG]

    Competition Hardware Descriptions:


    While looking at the hardware below keep in mind that the Play can do everything (except maybe DSD256) that the discrete rig below can do. By discrete, I mean we have dedicated components: DAC, USB Interface/XMOS, Power Amplifier, etc. This is one of the huge plus categories for the Play, cost effectiveness. For HiFi on a budget the $299 Play is hard to beat, especially knowing what you can get it to do with discrete op-amps!

    Update: 6/25/18:

    I have managed to run down 6 replacement capacitors for the Nichicon Muse stock caps below in the FUN01 XMOS module. Interested in finding out how this can/or if it will cause a change in the sound signature or quality. I found some Rubycon Black Gate™ “F” Series 100uF 25V (exact replacements to those installed below). I have never bought any Black Gates™ before because the cost of entry is usually so high, but I did once find some of the Non-Polar X (NX) versions for about $35 each, which is really good (same rating as these). Still looking for a good place to use those insanely good capacitors, but non-polar caps are pretty rare these days in digital audio circuits.


    I really lucked out on this latest seller, because I found out that despite the fact they have been soldered in a PCB before, it was never used. They removed the capacitors from new circuit boards and as a result, besides testing, the capacitors are all new! These carry a price tag around $50-$100 on Ebay for NOS or New (Other) or New, expect about a 50% price drop for used. Or you can do like I do and sit and wait, always looking but only buying when you truly spot something worth your money. New Black Gate™ F Series capacitors for $20 a piece? Sure! Read a little more here.


    [​IMG]

    [​IMG]

    I am providing some stout competition for the lonely “Play”. I will be utilizing my ES9038Pro DAC by ESS + “FUN01” v1.1 XMOS module (identical to Singxer’s SU-1). To keep this as even as possible, I will be making almost all head-to-head headphone comparisons using a single amplifier, when I’m using the internal Play amp I will notify the reader. The amp used on most parts is my S.M.S.L. “sAp-10” (a completely balanced headphone amplifier). Offering 2x 3-Pin XLR in + RCA in, with 1x 4-Pin XLR out and ¼” out. All loudspeaker comparisons will be made using my Pioneer “VSX-919AH” (4-Star WhatHiFi Winner) or my Yamaha “RX-V863” (I try both in the review), powering a pair of Wharfedale’s “Diamond 220” bookshelf speakers (5-Star WhatHiFi Winner). Throughout the review, Burson Audio’s impedance matching RCA-to-RCA Cable+™ will be connected between my modded Kenwood C-2 pre-amp (more on that here) and the power amplifier in use.

    [​IMG]

    I will confirm observations I hear over the loudspeakers with my Audeze “EL-8” planar magnetic headphones; to make sure there is really a tonal shift, or distortion, etc. The EL-8 “space-age material” diaphragms (thinner than a human hair) lay above the Uniforce™ voice-coils, which give what Audeze calls, “near zero distortion”, making the EL-8s a perfect choice for reviewing high-end hardware where reference quality and flat frequency response is required!


    [​IMG]

    The EL-8 also uses “patented Fluxor™ Magnet Arrays giving near double the power driving the diaphragm for even less distortion” along with Fazor™ elements as waveguides for a more “accurate waveform”. That is not to say the Wharfedale “Diamond 220” speakers are anything but exceptional, blowing away my Polk ”70s” in fidelity.

    [​IMG]

    We want flat frequency response because anything other than that is in effect, an EQ on the incoming signal. In reality there is always some amount of EQ from the speakers or headphones, especially the speakers. As the Art of Digital Audio says, transducers, especially in loudspeakers, are what hold back audio the most from the next leap in innovation.

    [​IMG]

    The “sAp-10” is a new device at Hallman Labs in a category of products I have been researching, balanced headphone amplifiers. This sAp-10 is an impressive piece of hardware, especially for only $199 (Amazon in May of 2018). The sAp-10 uses twin TI TPA6120A2 headphone amps, a TRIAD (FP24-500) US built transformer on board (and shielded), JRC NJW1195 four channel digital volume control with balanced phase, 2x Panasonic TQ2SA-3V Relays to prevent clicks/pops in output, 10x EPCOS (Siemens) film coupling capacitors, 3300uF Nichicon FW power supply capacitors and a lot more name brand parts.

    [​IMG]

    This is a step up from my Schiit Audio “Magni2” ($99 at launch) and a good fit for this review since the amplifier in the Burson Play is so strong (with V6-OPA Classics). Running a dedicated amplifier ensures that we are only reviewing the DACs. As long as your DAC combo has analog outputs, such as RCA or XLR jacks, you can always bypass the internal amp. For the purposes of being fair/unbiased, I will be using RCA outs on both DACs since the Play doesn’t have XLR, also known as “balanced” outputs like the ES9038 DAC. This also keeps the exact same wiring for both DACs, including the Burson Cable+™ RCA-to-RCA cable.


    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    The only difference between the two setups is the fact that the Play uses I2S (Inter-IC Sound, the latest and greatest) from the USB module and the ES9038 is still using coax from its XMOS. This was remedied before the review was finished, but not too long before. For the majority of the time all tracks in DSD were down-sampled to DSD64 (in foobar2000) because that is the maximum that the FUN01 can handle over Coax with the ES9038Pro using DoP (DSD over PCM). Note, this is how the review was run the majority of the time, even though it was corrected towards the end of the review.

    Review Hardware Info: v2.0 vs. v1.6 Burson Audio Play

    [​IMG]

    Burson Audio sent me a new revision of their Play’s primary PCB which is now v2.0 vs. v1.6. The primary upgrades were an increase in filtering by an increase in the number of ELNA SILMIC-II capacitors on-board. They replaced both Bourns trim pots with fixed Dale resistors (all other non-surface mounted resistors are Dales). For the -15V rail of the DAC/Amp, the v1.6 used an XL6008E1 while v2.0 uses an XL6019E1 IC. For the +15V rail of the DAC/Amp, the v1.6 used an XL4005E1 while the v2.0 model uses an XL4015E1 IC. The last two changes I noticed were the inclusion of an inline + removable 5A miniature-fuse with the 12V Molex connector and the 5W cement resistor was replaced with dual 2W carbon comp resistors in parallel. As you can guess from the names, most of these IC changes are newer revisions of the previous model (thus should be higher performing parts). From my conversations with Burson and what I have read, the main focus was lowering the noise floor without losing power. Increasing the quality of the power components will surely help out in this area.



    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    I talked again with Alex from Burson Audio on the topic of what was changed from v1.6 to v2.0 (to confirm my observations) and as I thought from inspection, it mainly has to do with the ICs used for the power delivery of the positive and negative op-amp voltage rails. Burson also wanted to remove the trim-pots due to Dale resistors being less likely to cause noise in the signal path. This latest revision has excellent depth characteristics that shine during my PC gaming sessions. Surely a lower noise floor can help give the listener the purist audio possible (free of audible noise). I was also told that Burson is no longer making the v1.6 Play, so I stopped my detailed comparison between the two from a sound standpoint. If enough people want this comparison, I’ll bring it back.

    Digital Noise/Mouse Distortion + Solution & Dedicated PC Power Supply: Fix that Hum Yourself!


    I have not noticed any pops, cracks, echo distortion (distortion that follows right after original sound) or other general distortion. There was one issue with digital noise that increases in decibel with mouse movement. This is a very old issue with digital audio, especially for the PC users. Luckily the community at Head-Fi.org found a fix, rather quickly in fact! New user “Dżonel” first suggested this simple mod and a handful of other users confirmed the fix works, including myself (you can find more on that here). The DAC still has a ground, it’s either from the 12V Molex or the normal DC power input, whichever you are using gives the +5V in its return path to ground (there must be one by KVL, Kirchhoff’s Voltage Law). This mod simply negates a 2nd (and thus optional) ground from the system. If you cut open your USB cable and clip the black ground wire, this noise will cease, or at the very least, drop in decibel by 75%. Some XMOS modules require the GND from the USB cable, usually those without a grounded chassis, so pick the cable you cut up wisely! You can also kill the USB ground at the DAC, but this is a more permanent option.

    [​IMG]

    The issue of mouse induced noise/artifacts is an issue that I have brought up to companies like Creative before the X-Fi series ever launched (over a decade). I am of the opinion that it has to do with high amperage draw GPUs and CPUs. There is the possibility that a noisy AC line/outlet could contribute as well. You can minimize this chance by minimizing the number of active components in your PC (and in your audio signal chain, start with a small, but high quality system). With regard to minimizing the number of components, I am speaking about the non – system critical hardware (as in don’t remove your CPU/RAM/Mobo/PSU). When we are dealing with high res audio, this noise usually isn’t an issue, but when dealing with a lower quality (like streaming) it sometimes is. I have also picked up on similar distortion when converting multi-channel audio to stereo with the Play. When noise on the digital line is an issue, the ES9038P is almost always the winner. According to “The Art of Digital Audio 3rd Rev.”, the ability of a DAC to reject noise/jitter/artifacts/aliasing/etc.. is the “greatest measurement of DAC performance”. But as we have already mentioned, it was simply a ground issue and was easily fixed, so not everything is so cut and dry.


    I’ll do more tests using compressed audio tracks vs. high res audio to see if I can duplicate it. I found out that the ES9038P is able to do gain compensation dynamically and as a result, lower the THD (Total Harmonic Distortion). I am building a 2nd PC for Hallman Labs, nearly identical to the main PC except this one has an i5 3570K de-lidded (heat spreader removed and higher quality paste added) w/ Cooler Master V8 GTS + ASRock Z77 Extreme6 + G.Skill DDR3 2133MHz 16GB (4x4GB) + Corsair HX750 (750W/62A) + Corsair 650D rig, running the Linux tailored to Hi-Fi, Audiophile Linux (“AP-Linux” link here). This will allow us to see if this is an OS related issue, or truly just a hardware grounding problem (well, in theory it should allow us).

    From the ESS datasheet “(The ES9038P has) Programmable THD compensation to minimize the THD caused by external components” and “Full-Scale manual/auto-gain calibration reduces device-to-device gain error.” This is exactly what Burson Audio said is causing the noise over a digital signal, gain offsets between devices. Alex said the next revision of the Play will be able to adjust this manually. Now we know after troubleshooting, the cause of our digital noise has to do with the ground in the USB cable.

    I also had to use a standalone power supply from a computer with a 24 pin lab PSU module with an on/off switch to give the 12 V Molex on the Play its power. I used a Corsair HX750 (high end PC PSU) for this to ensure the cleanest possible power (nothing else is drawing power, even the fan only runs when necessary). To make a long story short, I had a bad power brick and I ended up preferring how the PC power supply sounded over the replacement I got. I estimate having over 400 hours of use on the new revision of the Play. Even when putting it up against stout competition, the Play’s V6-OPA “Classic” op-amps really shine, especially as the amplifier. In fact, doing a direct comparison with just the Play and its internal amplifier vs. the entire other setup, the Play isn’t that far behind (using its own amp vs. the ES9038P on RCA out to sAp-10)!

    Opening Thoughts on Voicing of Burson Play vs. ES9038Pro + sAp-10:


    Switching from the SMSL sAp-10 + ES9038P + XMOS FUN01 combo to the Burson Play DAC/Amp combo has a noticeable tonal shift. I first noticed a high frequency extension of what seems to be an upper-mid to high frequency focused lift found in the Burson Play’s voicing (w/ V6-OPA “Classics”), not heard as prominently as in the other combo. I checked this with both DACs, the ES9038P + sAp-10 has slightly better low frequency extension and a mid-range lift vs. the slightly higher and a tad more detailed lift on the Burson Play DAC/Amp. I matched the volumes as close as possible without having to hook up the oscilloscope or multi-meter, by using the modded Kenwood C-2 (which has 2x V6-OPA-D “Vivid” op-amps running in the EQ amp and Flat Amp + 4x replaced stock 18V diodes with 16V Zener diodes). I also tried running 2x V5-OPA-S in the flat-amp using an adapter and flexible DIP-8 extensions. I ended up preferring the tone of the dual V5-OPA-S over the single V6-OPA-D “Vivid”.


    [​IMG]


    The Kenwood C-2 has been instrumental in this review, matching volumes with its 4-gang ALPS potentiometer and matching voicings through its above average tone controls (running on 2x V5i-D op-amps). When we flip the ES9038P from RCA to XLR in the later parts of the review, we find that the RCA outputs are darker, with less sparkle. I bring up small details like this to ensure I give an unbiased and clear opinion.

    [​IMG]

    The Burson Play’s performance in a movie or TV show usually comes off as more engaging, the upper-mid to high frequency extension causes environmental effects to echo/reflect around the room easier when using loudspeakers. In headphones they help give sound that extra sparkle and high frequency detail. Others may find the higher frequency focus as a distraction from the ideal flat line response, but at a time when High Resolution audio is king, I can understand the voicing selection.


    We are also talking about Burson Audio V6-OPA “Classic” (5 of them) in the Play vs. Sparkos Labs SS3601 and SS3602 (two pair) in the ES9038P. Every single op-amp selection/swap is going to change the overall tone of the sound when used in system critical positions, like these components do. As I learned after the initial review was written, the digital interface used and whether or not you are using balanced or unbalanced inputs/outputs, all have an impact on voicing and sound stage. I was surprised to learn that XLR (balanced) vs. RCA (unbalanced) had more of an impact on sound quality than Coax vs. I2S did.

    Listening Tests Streaming (Pt 1):

    (ES9038 on Coax & RCA)

    One of the things I have learned from doing multiple reviews is not to weight music too heavily. The people who do want to know about the music performance want to hear it across a broad range of different genre. The majority of people will use their hardware to do a lot more than just listening to music and the Play is focused on this fact. The main reason I can see to include a microphone is for the gamers and pod-casters, it allows you to have everything you need included in a plain 5.75” drive bay!

    [​IMG]

    While listening to some streaming off of Netflix through a Windows 10 PC, I noticed I preferred the Burson Play over the other combo (while using Coax and RCA on the ES9038P). This tells me that depending on what you are using your device/s for, either of my combos could be on top of the other, fidelity wise. Hell if you blindfolded me and started switching DACs, I would be hard-pressed to guess right much over 50%, because they are honestly that close in fidelity, especially through my Diamond 220 bookshelf speakers. There are minute details (yep, that is how you spell minute) that come out with the ES9038P that sometimes get lost in the gain of the Play. This isn’t always true and depending on the situation, I would pick the Play.


    When I am checking the differences between my two DAC combos I always turn off the tone controls of the Kenwood C-2 pre-amp so I can hear their voicing through just the flat amp of C-2 (where one of the Burson V6-OPA-D “Vivid” discrete op-amps are). The “Play” has this crispness to the sound, without being edgy and thus not fatiguing on the ears. The bass is also prominent and free of distortion. Usually when dealing with lower quality DACs you have to sacrifice either bass or treble to boost the other. This is not true with the Burson Play DAC/Amp combo, it seems both ends of the spectrum are here equally, as well as the mid-range. The Burson Play just has this lively feel to it that is truly musical in its qualities. One of the things I always try to keep in my mind is how the hardware sounds compared to being in person at a concert.


    [​IMG]

    When I switch back to the ES9038P combo, the first thing I hear is the mid-range clarity of the speech and when there is nothing being played, the noise floor is seemingly non-existent (Note: through the ES9038P’s XLR outputs, there is no noise floor, period). I have mentioned this fact before that the ES9038P + FUN01 seems to deal with digital noise better than the Play and its XMOS through the use of hardware demanding oversampling and noise filtering. The FUN01 has the ground plane split between the digital and analog sides of the board, something not usually seen on budget to mid-range priced USB digital interfaces. The FUN01 connects the analog and digital sides through digital isolators.



    System Critical Note: The FUN01 (clone of Singxer’s SU-1) requires power on both the digital/USB side AND on the analog side (5V power supply with center pin positive). This means you can’t use things like SBooster’s “VBus2” that kills the ground and power pins of the USB cable. The best you can do with a design like this is with something like AudioQuest’s “Jitterbug”. The Jitterbug is said to improve clarity and dynamics, bringing an overall more solid and precise sound. I was testing with and without, I’ve never been able to find any negative changes to the fidelity, so I usually run it. We are also Unable to use the modified USB cable for the Play (with the ground removed) with the FUN01.


    [​IMG]

    Oversampling is a crucial part of a modern DAC, especially the ES9038P which uses 4x oversampling in stereo or 8x in mono mode. The ES9038P has shown its ability to filter out noise that the Play allowed through. Now we know this digital noise has been brought on by having 2 paths to ground, one in the USB cable and one through the chassis ground (supplied by the power supply ground). Oversampling helps to push noise/distortion outside of the audio band, especially with modern filtering/shaping on top of oversampling. With specific shaped filtering you can filter out 50% more or so of the quantization noise than with a plain filter (Source: Art of Digital Audio)


    [​IMG]

    In simple terms oversampling means to sample at a higher rate than is required by the Nyquist Rate (a little over two times the top input frequency). Quantization (signal processing) error happens when going from analog to digital (ADC). This involves taking a continuous signal and segmenting it into “boxes” or “bins”. “Such errors are an inevitable result of the classification of continuously varying analog voltages into discrete digital bins. This quantization necessarily adds this noise at the level of ½ LSB (Least Significant Bit).” Pg.694 Art of Electronics Lab Manual 3rd Edition Luckily for us, the entire process is digital, from the hard drive to the XMOS and then to the ES9038P (or ES9018K2M for the Play), where digital is then turned to analog (DAC).

    [​IMG]

    Often after conversion from digital to analog (DAC), flat lines will have a roughness, also called “steppy edges”. This error can be smoothed out using a quality, low-pass filter. If you look on the back of the Play, this is what the “LP” means in the diagram. A common use of discrete op-amps, includes being used as high quality, low-pass filters with little effort.


    [​IMG]

    Sampling Rate: In simple terms, sampling involves breaking the waveform/graph into smaller and smaller chunks. However, the sampling rate must be taken across the horizontal/time axis. Note: In audio, when signal frequencies begin close to zero, the highest frequency simply is the bandwidth. This tells us the sampling required for a given signal must be dependent on the highest frequency in the analog wave. If the wave is made up of more than one frequency (such as in audio), it is the highest frequency that we are concerned with (lower frequencies are much easier to sample). So, if you buy a high res PCM/FLAC album that is rated at 96 kHz, the highest frequency you should see on an oscilloscope of the DAC outputs should be right around 96 kHz.

    Adele Live at the Royal Albert Hall Blu-Ray (DTS-HD MA 5.1 to LCPM 2.0)

    I have to admit I am a fan of Adele, she is one of the most powerful and spine tingling voices still with us. This Blu-Ray is an excellent showcase of her talents, from the power of “Don’t You Remember” to the country melody of the cover “If it Hadn’t Been for Love”, Adele never leaves you disappointed with this live album. I start out on the Burson Play using the internal amp into my EL-8s and there isn’t even a hint of distortion, noise, pop, cracks, etc. The EL-8s are so transparent on this album with the Burson Play, yet they maintain the body and depth of a live album. From the realism of the Royal Albert Hall echoes (time for a note to decay) captured, to the texture of her voice, this album transports you to London. Accurate imaging and timbre of the instruments intertwined with the powerful vocals, make this one of my favorite “reference” albums.


    On the track “Turning Tables” we are greeted with a very rich and textured voice, thanks to Adele. The piano on this track seems to surround the vocals of Adele on both sides and the violins come in from what seems to be higher (off the ground) than the vocals and piano, like birds swooping in from on high. Switching to one of the higher paced tracks, “Rumor Has It” brings the bass and body without losing the precision of this album. This is one of the best tracks to hear the dynamic range and the snap/speed of transient response of the album. (Transients as defined by Head-Fi “the leading edge of a percussive sound. Good transient response makes the sound as a whole more live and realistic.”) In contrast, a bad transient response would come off smeared or muddy.

    [​IMG]



    I switch over to the ES9038P + FUN01 and finally the ES9038P is able to pull ahead in the upper-mid to high frequency territory. I think the ES9038P has a better balance on this album than the Play does (tone controls are off on C-2) and it has better low level detail. At the top of the SPL (Sound Pressure level) the sound has a warmth and texture to it that is slightly lacking on the Play. It’s like you dialed the presence knob up when going between the Play to the ES9038P. To those who don’t play guitar, presence means how “close” the sound seems to you. Neither setups are really lacking, but we are doing a comparison here, which is far from easy with how strong each of the setups are.

    I flip to the cover, “I Can’t Make You Love Me” and from the first note you feel like you are standing there watching her. The sweetness of her voice shines through on this track while maintaining pitch across her unbelievable vocal range. Only a few artist before her could even compete with her capacity and vocal stamina, such as Aretha Franklin or Whitney Houston. The overall realism of this album is up there with some of the best, from the echo of her voice around the hall to the crowd singing on the track “One and Only”. The dynamic range could be glass shattering, yet I don’t feel my ears getting tired/fatigued (when played at a reasonable level). Now we go back to the Play and cue up the song “I’ll Be Waiting”, as if on cue the chills go down my spine. It’s very hard to describe these changes in sound quality. It’s almost the way it “feels” vs. how it sounds, people use the word “musicality” to describe this sensation. The Play seems to have slightly more body to the sound, the small details seem more focused or just come out with less effort.

    [​IMG]


    I noticed when I was playing the album over DTS-MA 5.1 (into LPCM 2.0) I kept hearing what sounded like sibilant distortion, but when I flipped to Dolby 2.0 it stopped instantly. This tells me that this issue has to do with down-sampling 5.1 into stereo using PowerDVD 17 Ultra. For whatever reason, this issue doesn’t seem to bother the ES9038P combo as prominently. Once I had that issue figured out I was left with a hard decision to make, deciding which DAC wins this section. There is a small downside for the Play, it lacks the complete blackness of the ES9038P’s background, even in between notes you can hear this difference. However, this is not a detail that you’d notice right off the bat, maybe not even the first few times playing the album. Still, for this reason I have to give this section to the ES9038P. If not for this little difference I would have called it a tie.

    Tedeschi Trucks Band Live from the Fox, Oakland (96kHz/24-bit FLAC)

    [​IMG]

    I have seen Derek Trucks in both of his former groups, The Derek Trucks Band (twice live) and The Allman Brothers (four times live). I am going to see Tedeschi Trucks Band for the first time in July (in the town of my old engineering school, Raleigh, NC!) and I am excited to hear this duo finally in person! Basically, I know how Trucks sounds when he plays live and I have listened to his studio work for hundreds of hours, maybe thousands (car trips add up fast). Without further ado, these are my thoughts on the performance of these components during this excellent live high res album.



    We begin with the ES9038P + FUN01 going into a SMSL sAp-10 balanced headphone amplifier, although we are using RCA for fairness sake. I have considered comparing balanced (the hardware interface) out of the sAp-10 once I have the “Blue Dragon” cable and EL-8 connectors from Moon Audio to a 4-pin XLR from Neutrik. This is the balanced output from the sAp-10 that is offered alongside the ¼” jack.


    [​IMG]

    Back to the music at hand, this is one of the most lively and upbeat live albums I have had the pleasure of listening to in a while. This will be my first opportunity to listen to this album, for the sake of the review! From the start of the first track we hear the crowd noise tumble into our sound field, the drum rolls left to right, everything seems just how you want it. Flat curve with complete neutrality throughout the frequency spectrum and even though they jam out hard at The Fox, it’s not fatiguing. I know that my EL-8s definitely help in that area, though, also having the Kenwood C-2 really is a life saver and worth every penny. The C-2 comes alive further when we take the time to mod it for modern discrete op-amps! Giving the tone control the V5i-Ds from Burson Audio was an easy call, these tone controls are a crucial part of my rig. Each album has its own EQ and I have an EQ that I want to create for my system, so a pre-amp caters to this need. At least if you get one with decent tone controls like we have on the C-2. All final impressions are done with the tone neutrality (tone controls disabled/off).


    The guitar is placed right in the center of the sound stage, the crowd seems to encircle the guitar during the track “Keep on Growing”. If you listen, close your eyes and really listen, the crowd is all around you and the instruments come from dead center, if the stage was a 360 sphere in front of your face. We get to the bluesy, slower “Bird on a Wire” piano opening, which I love. Growing up with Aretha Franklin and Led Zeppelin, creates an eclectic ear. An ear that loved Zeppelin’s “Trampled Underfoot” because of the keyboard solo! This album hits so many genres without having to try, it transplants you. Then in comes Susan Tedeschi, who delivers all the vocal sweetness and texture like the great ones from the past. Ever since I heard her sing “Midnight in Harlem” at Eric Clapton’s 2010 Crossroads on Blu-Ray, I was sold. The fact she married one of the top touring guitarist in the world, was definitely a plus! “Bird on a Wire” is such a powerful track, Tedeschi gives a soulful and church hymn inspired tune a modern feel, with her own special touches at every chance she gets. The sound of Tedeschi coming in the EL-8s compared to the piano, drums and backup singers, almost seems to be coming from “above” you, like an angel singing down

    [​IMG]


    It’s time to switch over to the Burson Play after I have a good sense of the ES9038P and its performance on coaxial. I can’t deny it, I listened to “Within You, Without You” twice, once with the ES9038P + FUN01 and once with the Play (both setups were using the SMSL sAp-10 headphone amp into the EL-8 open-backs). I put the Play on and closed my eyes, in order to imagine this sound field and pick up on the details I noticed a change with. The first thing was the jump in decibel (which I had to correct obviously), but it is worth noting that the Burson Play overall has so much more gain than my ES9038P, maybe 4x. The Play is loud enough to easily damage your hearing, especially when you are using things like a pre-amp with a power amplifier. Be safe with your gain levels and protect your hearing!

    What I noticed first was the goose bumps on my arms when using the Play, honestly. The first time I played the first track, it was like I was actually there (when I closed my eyes and focused on the sound). I’m doing it now with the track “These Walls”. The guitar seems to originate from some ancient stone cave due to the sound of the instrument and the echo captured, but there is a large crowd of people around too. This strange instrument being played, not one I can name (sorry guys/gals), it seems to grab your attention and sort of tickles your brain with a melody almost hypnotic in its timing. Derek Trucks starts to play along with them, sounds like he is using a slide guitar on this track. The drum comes in, slowly at first, with a jazz type sound and all of a sudden we have Susan singing again. This is a song I absolutely love, titled “These Walls”. It’s so easy to pick out each instrument when you open your ears and just sit and focus on the track. The Play has so many strengths and I’m not just saying that for the purpose of this review, I plan to prove it actually. We will eventually put the Play and the ES9038P + FUN01 into RightMark and my oscilloscope to see what is going on!


    [​IMG]
    This will probably be the longest listening test of this review because this band means a lot to me and I hope this review will help to expose this album as one of the few great modern releases by a real rock band. They always say, write about things that are meaningful to you, well here you go! Susan Tedeschi is able to build up the momentum of the track so well, but then we transition to a slower paced slide guitar and what sounds to be an acoustic slide of some sort. Then Derek Trucks is just playing normally, he just sounds like that on a normal guitar. The man is a genius when it comes to playing, you can quote me on that.

    The Play comes away here really cementing the way I feel about how it stacks up. I only hope this continues once the ES9038P is running on I2S also! That will be something that should interest people who may not be interested in the overall review topic! Is I2S that important where a DAC/Amp combo can compete against using all discrete components? The placement and dynamics that the Play is able to achieve, really creates an impressive sound field to get lost into. The track returns to what it opened up with and then it closes out as smoothly as it came in. I’d probably have to give the Burson Play the win (while the album was playing through coax on the ES9038P setup).

    [​IMG]

    A Short Note on Converting PCM to DSD with Foobar2000:


    I tried playing the Tedeschi Trucks album with DSD64 using SDM Type D (best of the available Foobar2000 DSD converters) from its native 96 kHz PCM and I ended up hearing what sounded like clicking coming from random locations. I tried both DSD128/48 and DSD128, I didn’t experience this artifact using these settings and the overall sound signature seemed livelier. I am listening to more of the same Tedeschi Trucks album in DSD128 and it truly sounds remarkable. “Don’t Drift Away” in particular draws emotion out of you like Otis Redding can in songs such as “Cigarettes and Coffee” or even “Chain Gang”. Perhaps you are more into Aretha doing “The House that Jack Built”? Anyone who enjoys those tracks will enjoy this live Tedeschi Trucks album in my opinion, it’s definitely worth checking out. The jam out track “Ali” brings in a lot of brass instruments that really help to open this album up to a huge audience, between the excellent trumpet work and the always groovy playing of Trucks, you are in for a treat!


    [​IMG]

    Just for the sake of pointing it out, I switched back to DSD64 on a track that was clear during DSD128 and sure enough, the clicking had returned. As soon as I switched over to DSD128, before even hitting apply, the clicking was gone! So there must be a limitation of DSD64 with this up conversion that still needs to be ironed out with foobar2000. For now if you are going to convert PCM into DSD on foobar2000, stick to DSD128 or DSD128/48.


    Balanced vs. Unbalanced: Understanding the ES9038’s Performance

    [​IMG]

    I think the huge difference in unbalanced vs. balanced sound quality needs to be pointed out. This is an advantage that stacks up in favor of the ES9038Pro for the no-holds bar patrons of HiFi HW (large budgets). Sadly it is true, in order to get an amplifier with XLR in will cost a pretty penny. There are a few exceptions to this rule, especially if you go with used equipment (I do this, see Pioneer VSX-919AH) or DIY.


    When using my XLR/balanced setup the sound stage seems to expand by at least 2 fold, it’s immediately noticeable if sitting near the sAp-10 with both RCA and XLR hooked up from the ES9038P (switching between the 2 inputs because the ES9038P can output both). It’s not only sound stage size that changes, the texture of the highs and lows have more detail. The dynamic range seems to be better too, the XLR input from the ES9038P seems louder on the sAp-10 by a few decibels, nothing crazy. Just the change in the details you can pick up on, like someone hitting a mic stand or the pianist foot tapping against the ground while playing brings an old album alive again.


    [​IMG]


    When we are comparing brass instruments you might as well lay down the cards on balanced audio, it’s not even close, especially on the high frequency side. The RCA output of the ES9038P is a tad darker, even when running through the C-2 with V6-OPA-D “Vivid” op-amps for the flat amp. Perhaps this is why I kept hearing a high frequency shift with the Burson Play for most of the review (because of the darker RCA signature).


    [​IMG]

    Perhaps the ES9038P has a darker signature on the RCA outputs than the XLR or, it could also be how the sAp-10 handles the two input types. Sadly I only have one amp that can take XLR in, so I can’t confirm this observation. I do have another XLR DAC on the work bench (see DSC1 article). Over the days following the release of this review I will be making measurements trying to get all of these audible claims to show up on an oscilloscope or in RightMark, so keep an eye out for the update.

    Adding I2S Input To ES9038 DAC:

    [​IMG]

    [​IMG]

    The job of putting I2S into the ES9038P DAC enclosure is no small feat. The mod takes someone who can use both soldering irons and power tools! Most decent CAT6 jacks will require a 6/7” to 1″ hole in the back of the DAC to fit the jack. Then you need to remove the stock pin header from the DAC PCB so you can hard-wire the I2S line (in my case, using Belden Catsnake™ CAT6A) between the I2S header location and the punch down/keystone jack found on the Neutrik plug. Using a keystone jack makes it easy to change the order of the wires, if ever needed in the future.


    Not all XMOS/Amanero units have the same I2S output order, even just leaving a pin out can wreak havoc on your Hi-Fi experience (if you don’t adjust the order to match)! Once you punch down the CAT5/CAT6 you can hook up your CAT6 cable between your XMOS/Amanero module and the DAC’s CAT6 jack you just installed. Congrats, you now have a custom DAC (takes just one mod to qualify for the word “custom”)! If anyone has questions about why I did something or how to apply this information and the info found in the I2S Catsnake™ article, please email me at keith@hallmanlabs.com for more info.

    I2S opened a huge door for the ES9038P across the board (RCA or XLR). The highs are better, more transparent signature, less fatigue on an already low fatiguing setup. Then of course the ability to now play DSD256 or 32-bit FLAC at 352.8 kHz+ adds to our High-Res options!


    Before, running the ES9038 on coax was a little unfair, but not by a stupid amount. I apologize as the majority of this review was written with the ES9038 setup running on coax, but I will be including listening tests where the ES9038 is also on I2S (like the Play is by default). I hope this little “change in our program” will go to showing the strengths of XLR + I2S vs. RCA + Coax. This will give us a sub-review in the main review; as I will distinguish Coax tests from those made on I2S and see what differences or similarities exist.

    DAC Audio Performance Measurements


    Frequency Response: White & Pink Noise Testing

    There are a handful of different types of “colored” noise, white noise has equal dB across the entire frequency spectrum (limited in how high the range is in frequency by the track/album used). While “pink” noise has a perfectly flat line in the audible range with a -20dB drop (at varying slopes/shapes) after 20 kHz.


    A perfectly flat line (on the FFT) is what we want to see on this first test (white noise is up first), and both DACs come very close using this method to “flat”. Pink noise is what you see below the first two photographs. Sadly I don’t have equal quality digital files (such as DSD256 as I do for each frequency vs. a sweep or colored noise that I only have in CD quality).

    Now let’s look at how a 96kHz 24-bit FLAC pink noise and how this shows us the high frequency roll off.

    ES9038Pro:


    [​IMG]

    Now, with the ES9038Pro, you can change the behavior/shape of the high frequency roll-off using FIR filters found in the menus. Each of the 10 or so filters have a noticeable impact on the shape of the FFT. This is one of the examples that show the flexibility of the ES9038P. We can see just from the last two scope captures that the Burson Play does indeed have a higher dBV value at parts of the higher frequency end of the FFT than the ES9038P (this matches what I noticed listening).

    Note: I am working on doing frequency response using discrete frequencies as I have them in DSD256. However, I have run into some difficulties getting a fair score on both DACs. I am also working on THD, SNR, Jitter, etc.

    Thanks for being patient!

    Closing Remarks: Burson Play Comes In First In Its Weight Class:

    These two setups turned out to be much closer in fidelity than I would have ever guessed from the start of the review. We were able to gauge how much of a difference I2S has over Coax and then I compared balanced outputs to unbalanced outputs. Most reviewers would never change something so dramatic during a review, but I found it insightful to do so. Without switching to I2S or balanced outputs, I would have probably rated the Burson Play slightly too high. The Play is definitely an excellent choice for those who want your DAC/Amp together in a mobile package, but still want the option of rolling op-amps. The Play is a unique piece of equipment that shows us that size can be deceiving and is an excellent value for the money. The sAp-10 amplifier alone is larger than the entire Play, much less if we take into account the DAC and XMOS unit that make up the other combo.

    Overall I have been thoroughly impressed by the performance and fidelity of the Burson Play, both from a DAC standpoint and as a separate amplifier. When you think about how the Play is laid out, the single-DIP op-amps each power one channel (L/R) of the headphones amp and the pre-amp out (that can be run at the same time as the headphone ¼” out). Throwing in a decent quality mic input powered by an ES9018K2M, gives the gamers everything they need in one enclosure. This is a solid rig all around and with just a little tweaking it can be a great rig! I can easily recommend this for anyone who admires simplicity and quality for a budget conscious price, wrapped up in a compact package. Burson Audio has really found something special here with the Play and 5x V6-OPA Classics!

    Hallman Labs Award Winner for Best DAC/Amp in 5.75″ form factor!


    Pros:

    • Ability to upgrade at a later time to a higher end rig.
    • High mobility/portability due to a very compact design.
    • Entire chassis acts as a heat sink and entire chassis is grounded.
    • Excellent quality audio for the cost. The Play is able to compete with ES9038PRO DAC and even win a few of the tests.
    • Plenty of power using the internal amp, powered by two single-DIP op-amps.
    • Ability to slide the Play right into a PC 5.75″ drive bay.
    • Ability to listen to RCA and headphones outputs simultaneously.
    • Uses I2S to communicate with XMOS.
    • Can be powered a variety of ways.
    • Has a remote and a few other included accessories, sounds small, but an important detail.


    Cons:

    • Can get fairly warm, but these are the realities of a Class A amplifier and the components can handle it.
    • Not as good at rejecting noise as the ES9038PRO DAC can. The FUN01 also plays a role in the cleaner signal. (Note: this opinion is after fixing the USB ground issue.)
    • Unable to get a Play that uses the Amanero, although you can easily get one that fits if you want one, just not stock.
    • The Play’s display could give us more info and the inclusion of a simple menu would be nice. Just give us a few filter selections and a few other basics menu options (as seen on the ES9038P’s screen).
    • There can be a digital noise issue because of the fact there are two paths to ground in the Play if you leave the USB cable’s GND connected. I disconnected mine as advised on Head-Fi and the digital noise stopped. Still have to list this as a con though, the average consumer might not want to cut into a USB cable or de-solder something.


    Thanks for reading the 3rd review at Hallman Labs! On deck is Part 2 of my Discrete Op-Amp Showdown and I will be adding technical aspects to this article as time goes on, such as performance measurements.

    Burson Play - Desktop Power
    Written by Dobrescu George
    Published Jul 31, 2018
    5.0/5,
    Pros - - Price/Performance Ratio exceedes most products in the 300USD Price Range
    - Textures Quality is impressive
    - Soundstage is both deep and wide, very holographic, but doesn't spread unnaturally, basically an excellent presentation of a large soundstage
    - Tonality is Spot-On, without any coloration, or any kind of tilting, it is neutral, natural, energetic and vivid
    - Dynamics are top notch
    - Excellent amounts of control over the sound, even at very high volumes, with both easy to drive and very-hard-to-drive headphones
    - The overall sound is quick, textured, punchy, indicating both a really impressive impulse response, and a really nice power delivery solution
    - Detail and resolution are also very impressive, some of the best there can be at this price range, outdoing most 300 USD competition with ease
    - Full Metal, Trustworthy build quality
    - Firmware is as stable as it can be, no crashes, no random disconnects, it simply works
    Cons - - The unit gets warm while in usage, meaning that if it is used inside a desktop PC build, it needs some cooling around it, not an issue if it is used on a desk
    - High output impedance leads to hiss with very sensitive In-Ears, especially with IEMs lower than 16 OHM in impedance
    - High output impedance also indicates that it will perform slightly different across certain IEMs, especially relevant for IEMs which have their impedance lower than 16 OHM, or those which are sensitive to output impedance
    Burson Play - Desktop Power

    Burson is a large company working in high-end Desktop Audio components, including those which can be incorporated in a Desktop PC build. Burson Play is one of their highest-rated DAC/AMPs which can do way more than the price tag or the name implies, and we're going to also put it against much more expensive portable products, to tempting you to go desktop soon.

    Introduction

    Burson Audio is an excellent example of a high-end audio company. They have a 5-year warranty for their products, which by itself is amazing, but they also note on their homepage a lifetime-warranty for their OP-AMPs, so you know you're in for a treat working with a company which trusts their products this much. Their public relations people are also native in English and will provide you with utmost care in service along with good advice in picking the product best suited for you from their offer. They will also be taking care of you with their warranty, and make the process as easy and hassle-free as possible, for five years after purchasing their products, but having seen the quality of their products, we don't feel you'll be needing warranty any time soon.


    It should be noted that I have absolutely no affiliation with Burson Audio, I am not receiving any incentive for this review or to sweeten things out. This review is not sponsored nor has been paid for by Burson Audio or anyone else. I'd like to thank Burson Audio for providing the sample for the review. The sample was provided along with Burson Audio's request for an honest and unbiased review. This review will be as objective as it is humanly possible, and it reflects my personal experience with Burson Play. Every opinion expressed is mine and I stand by it, the purpose of this review is to help those interested in Burson Play find their next music companion. This review is part of a mini-tour organized by Burson Play and this unit will also be reviewed by other reviewers during this tour.

    Packaging

    First things first, let's get the packaging out of the way:

    Burson packaging is not quite as fancy as some might expect, in the sense that the outer box is a simple black cardboard box, thing which may seem a little disappointing at first, but we'd like to remind everyone that Hard Disks come in plastic bags, and as Burson Play is marketed as, and can be treated as a Desktop computer component, this rather simple presentation isn't quite that unusual.

    After you open the initial package, you see the mastery of Burson products, as everything has its own compartiment, and the Burson Play unit itself is seated quite nicely in its own cutout. In the lateral compartments you can find all the accessories you'll be using to enjoy and have fun with Burson Play.

    The unit comes with a plethora of accessories, including cables, Power adapters, and other miscellaneous which you will surely find handy when along the way.


    Here's a full list of those accessories:

    Burson Play Unit
    PC Connection Cable Set
    Remote Control (optional)
    6.5mm to 3.5mm Socket Adaptor
    RCA Cable
    2.5mm hex key
    Power Supply
    100-240V AC


    There's not much we could have wished for to be included in the package really, they really thought of everything, and there are even small silicone feet to attach to your unit if you plan on having it sit on your desk and such.

    Technical Specifications

    [​IMG]



    Build Quality/Aesthetics/UI/Firmware

    The build quality of Burson Play is as good as it gets, which is like a tank. We're talking about a medium-sized device which is mostly a heavy metallic unibody. There is no flex if you press on the unit from any direction, the whole thing feels like it can withstand a serious amount of stress and pain, although, being a desktop device, this probably won't be the case.

    There is a volume wheel on the front, which is a digital controller for the volume, which works great. You can even press on the button to mute to unit, and you don't need to be too careful with it, as it is made really well.

    [​IMG]

    [​IMG]

    [​IMG]

    There is a 6.3mm plug on the front, which is just lovely, as it will be quite helpful in using some serious Desktop Headphones, and since you have a 6.3mm to 3.5mm adapter included in the package, you really can fit any headphone with Burson Play. There is a Microphone jack as well with the unit, so you don't need to worry about plugging in your favorite mic at the back of your computer.

    There's a lovely display on the front of the unit, which displays the current volume in a deep blue, made of small LED lights. This gradual volume is in perfect sync with the volume wheel, as the volume wheel does not rotate freely, but has small dents which let you know when you increased or decreased the volume with a unit. This volume goes from 1 to 99, but for most headphones, IEMs and even if you connect a Speaker with RCA cables from the back of the unit, you're most probably going to stay within the first 42 steps of volume, unless you have some really power hungry headphones.

    The aesthetics of the unit are pretty cool, our review unit being black, with a stylised Burson logo on the front, and with most of the unit being made out of a matte metal.

    At the back of the unit you can find a USB plug for connecting Burson Play to your computer, a Molex Power Adapter, to feed power from your PSU to your Burson Play, a On/OFF Switch, and a Power Plug for connecting the outer power adapter to your Burson Play, which is used if you use Burson Play on your desk rather than in a desktop computer build. On this note, Burson included even a cable to route Burson Play from a USB Header from your Motherboard, so you really have all the bases covered, provided the case is a normal or larger sized desktop case.

    Now, a few notes about the build, Burson Play was thought to also be used as part of your dream multimedia PC, so it is constructed in such a way that it would fit in most computer cases just fine, providing an even better ergonomic and comfort than if it was constructed as a standalone desktop unit only. Even so, at Audiophile Heaven we mostly rely on iTX cases, which simply do not have the space necessary to install Burson Play inside, but we feel that it is a beautiful device to have on your desk while working or listening to music.

    [​IMG]

    The firmware and UI are very simple, or rather, not needed. Burson Play works natively with multiple desktop computers we have in our office, and it simply doesn't mind what kind of signal it is being fed. The drivers install easily on windows, and you can just enjoy listening to music as soon as you plug it in. It is capable of decoding PCM signals up to 384kHz / 32Bit (Highest there is), and DSD up to DSD 256, including Native and DoP. Basically, it covers anything you're likely to have around. The best part is that it even works on Android and iOS, and also MAC, so you have one device you can use with any other devices you have, from a Tablet, to the most powerful desktop setup.

    The output impedance is rated at around 8 Ohm, which means that some lower impedance IEMs will have some hiss, and that some very efficient, low impedance IEMs might also sound a little different on Burson Play than they do on most other sources. This means it is more of a Headphone AMP than of a IEM AMP. There are iFi products on the market, like iEMatch, which can help alleviate this.


    Other than that, Burson Play hasn't made any kind of issue for us, over the course of a few weeks of serious testing, it hasn't restarted or disconnected once, so we can say it is as stable as a device can be.

    At the end of the day, the build quality, the aesthetics and the Firmware are all within what we consider a Golden Level.



    Sound Quality

    The sonic signature in this review is measured with the default OP-AMPs, and we also measure the sonic performance of Burson Play's DAC, as we had the chance to connect it to our speakers, as the main DAC unit in our main listening setup in our office.

    [​IMG]

    There are a few other setups with different OP-AMPs, and we are going to look into those in a follow-up review as well, but right now we'll be talking about the least expensive, base configuration.

    The main way to describe its sound neutral. So dear neutral that it makes slightly warm sources like Opus #1s or Cayin N5ii sound quite warm in direct comparison. Other things that can be said about the sound of Burson Play is that it is powerful. The control and authority it has over sound is absolutely incredible, and we heard the flagships in terms of portable audio before, so we are accustomed to a really well-controlled sound, but Burson Play is totally incredible, especially when we consider the fact that it costs about 300 USD, which is roughtly the same price you pay for an entry-level to midrange Digital Audio Player.

    Bass


    The bass of Burson Play is very deep, and very revealing, but most important, very controlled. There is no real trace of warmth or coloration in the bass, being absolutely neutral, but that is pretty much desirable from a source, especially from a desktop DAC/AMP, being one of the more important things when you own a larger collection of headphones and IEMs and you want to have something to drive them all without coloring their signatures. The bass goes as deep as you can imagine, but most importantly, it is very controlled, quick, can explode extremely quickly and recover just as quickly. Without much coloration to talk about, the bass can come off as very agile and able to bring the best your headphones and IEMs can do, especially for a DAC/AMP at this price point. When it comes to a desktop DAC/AMP, there are characteristics like the slew rate of the amplifier which may be quite a bit better than a similarly priced counterpart, but that is mainly because the physics of a desktop component allow it to be physically larger, thus allowing for higher quality components.

    Midrange

    The midange of Burson Play makes itself remarked once again by how transparent and colorless it is. The textures are fairly good, and everything feels right into its place, although, if we were to name something that really stands out, that is the amount of detail Burson Play has. The fact is, most high-end Portables reach this level of raw detail in general, and not most midrange devices, and since the most prominent two Players from the midrange price bracket we reviewed have been Opus #1s and FiiO X5-3, and we liked both of them, this is saying quite a bit about Burson Play. You can hear details, micro-details, textures and micro-textures if your Earphone, Headphone or IEM is able to reveal them. Burson hides nothing and acts exactly like an ideal source should, it colors nothing, hides nothing, simply presenting the listener with an accurate representation of the music that is being played.

    Treble

    Now, the treble, is a story which we love, but which we understand will change with other OP-AMPs from Burson. The treble is really well-extended, energetic and neutral, a touch bright and cold, akin to how most ESS-family devices were described to sound in the past. This means that the sparkle in the cymbals of most songs will be very alive and lively, there is a stunning clarity all-around, and there is no smoothing or toning down of the treble. This doesn't say very much on its own, when we consider that most sources are supposed to sound this way, but it does say a bit about how universally match-able Burson Play is. Since it is so neutral, it won't color Headphones, so it provides a fun, punchy, sparkly and interesting experience with very different headphones, like Audeze LCD-MX4, Ultrasone Signature DXP, and Beyerdynamic Amiron. The treble texture is normal, it isn't very smooth nor very grainy, mostly within what we'd consider a natural treble texture, the IEM or Headphone doing most of the work to give it a tilt either way.



    Soundstage

    Now the soundstage is something that differs widely between devices, sources, DACs and AMPs. Here, Burson Play is a good performer. The soundstage has a good size and depth, a generally pleasant layering, with enough layers for instruments to each play on its own, but it doesn't expand unnaturally, so instruments which are supposed to sound closer will be closer and forward, while instruments playing in the background will stay in the background. All in all, the width and height, along with the depth of the soundstage, are what we'd consider to be amazing for 300 USD, and good for any price range.



    ADSR/PRaT

    The ADSR / PRaT are probably the other interesting part of Burson Play, since we first established that it doesn't really color sound much, and that it has a good soundstage, so the only remaining part to review (besides comparisons), is its ability to render textures. Here, we feel it does a good job. The macro textures are rendered with good clarity and expression, Masa Works Design and Mindless Self Indulgence both sounding pretty vivid and lively, while micro textures are well defined, but not brought very forward in an more revealing way. While they surely are in the sound, and you can hear them with IEMs and Headphones prone to revealing them, they aren't quite as revealed as the macro textures. We're quite curious how the other OP-AMPs will affect this part of the sound, as Burson markets the Vivid Burson Play as being able to really bring a lot more of the textures and micro-textures forward. We will acquire a set of the higher-end OP-AMPs to review them in a future article as well.



    Desktop Usage

    This is the place where we'd have our Portable Usage section, if we had one. At least for this review, it would make no sense to discuss how portable Burson Play is, as it is transportable at best. This is a full fledged Desktop Amplifier unit, so we can study other parts of it in the process.

    [​IMG]

    First thing, there is no cable or microphonic noise in Burson Play. We noticed that some users mentioned this being an issue with certain DAC/AMPs from other companies, so we did a little study to see if Burson Play has any, but there's no trace of such a thing. We're quite glad to note that we noticed it being dead silent regardless of where it was placed, including if it was placed on top of our speakers, so we can say that it is also well shielded from EMI or electromagnetic interference.

    The heat is another aspect we need to discuss about, as Burson Play gets pretty warm during usage. It won't get hot to the touch, but it gets fairly warm to the touch, close to how warm an iFi iDSD Black Label Micro can get while it is in usage, indicating that it may not be the best idea to place Burson Play within a desktop build, unless you can ensure that there is a good amount of airflow around it, or if you can point a fan towards it to make sure it stays nice and cool. This isn't a big issue while it sits on a desktop though, we can't notice that it is warm to be honest, unless we need to turn it off, thing which also needs to be mentioned. Burson Play needs to be turned off by either plugging out its power source, or using the button in the back. In a Desktop Computer build, this wouldn't be an issue, as it would turn off when the computer is turned off, but in a desktop usage, you need to flick the switch at the back to turn it off.

    You can always engage the volume button to mute the sound, by pressing on it, and this works fairly nice.

    There is a microphone 3.5mm input, although we haven't had a chance to test a lot about it, it works with our simpler microphones just fine.

    Now, we also have used Burson Play as the DAC unit in our desktop setup, and we need to note that it is doing an amazing job. It is better than other devices we had from this price point, connected in the same manner, like HIDIZS DH100, which we were using before connecting Burson Play, and once we had Burson Play in place, we realised just how great of an implementation of the DAC inside Burson has, since Burson Play manages to bring out far more detail to the ears of the listener, and to have a much better treble extension, feeling more natural and wider.

    This might also be because Burson Play also has the 2xRCA outputs which are designed for it to work as a DAC for a pair of speakers with their own AMP, while DH1000 is designed to be a DAC/AMP only, without a Line Out.


    Another thing we've noticed during our time with Burson Play is that it simply works. It doesn't matter which one of our machines it was connected to, it simply works, it never disconnects, never restarts, simply put, there is nothing to stop you from enjoying music while using Burson Play, and we consider this a true virtue for a device, and a really pleasant first experience with Burson Devices.



    Comparisons

    Most comparisons have been taken with Edifier S1000DB, Audeze LCD-MX4, Dita Truth, Hifiman RE2000, Ultrasone Signature Studio, Hifiman RE800, Sennheiser ie800, Beyerdynamic Amiron, Ultrasone Signature DXP and iBasso IT04.

    [​IMG]

    Burson Play vs FiiO Q5 (AMP5) - Here's a tricky one, as, if you've been following our articles, you probably know how much we love FiiO Q5 and its price/performance ratio, offering virtually the same sound as FiiO X7mkii, for as little as half of the cost. Starting with the build quality, both devices are fully made of metal, both devices have a volume wheel, and both devices have a build quality that can take a beating and come back for more. Both devices are shipped with all the extras you could ever require to drive them, including all the cables, connectors and accessories to take full advantage of them. The differences start to appear when you consider each of their intended usage scenarios. FiiO Q5 is a stack-able DAC/AMP which you can strap to your smartphone, to have the sound of a high-end DAP, while Burson Play is a midrange-priced DAC/AMP supposed to sit on your desk or inside your desktop computer build. This means that you can only use Burson Play while inside, while you can take Q5 on a trip on a mountain, or when biking and such. The differences in sound are smaller than you might expect, and they are in the advantage of Burson Play. By Power Rating alone, Burson Play can drive virtually anything that is on the marketing at this moment, save for that one or two headphones that need a little more push. From IEMs to most Planars, it wouldn't have an issue to drive Audeze's heavy artillery Headphones, but it can also work well with IE800 from Sennheiser. FiiO Q5, on the other hand, is also extremely potent, being able to drive almost anything, starting with IE800, up to Audeze LCD-MX4, which it drives incredibly well. Now, the largest difference between the two isn't in the detail, or in the tonality, as both are pretty neutral, and their detail levels are similar. When it comes to their textures, Burson tends to express a little more detail in the macro and in the micro textures, showing a little more of what is going on within the texturization of a musical instrument, and having a larger power source, it makes sense since it has improvements in slew rate and impulse response, which simply aren't quite as possible within a portable, battery powered-device. Of course, this also increases the noise floor a tiny bit, since batteries are a tad quieter in terms of noise floor generally speaking. There is also a difference in how controlled and in how much authority Burson Play has, thing which can be heard even with something smaller and easier to drive, like Ultrasone Signature DXP. Especially at louder volumes, Burson Play keeps a better overall punchiness and impact, along with better control especially over the lower frequencies, but then again, FiiO Q5 was already excellent in this aspect, just imagine adding a bit more topping over an already excellent thing. Since the two setups are priced similarly, with Q5 costing a bit more, we can say, that despite those facts, both are excellent value for their money. This is because Burson Play requires more to be enjoyed, as you can just strap Q5 to the cheapest smartphone on the market and go on a trip, bus ride, or a walk and enjoy its quality, while Burson Play, by nature, is a desktop device, so although sonically it can sound even better than Q5, you can't listen to it while on-the-go, which was Q5's main focus. Adding to that the fact that Q5 also has Bluetooth, and you can see that if you require a portable device, Q5 is really an excellent choice, while if you don't need it to be portable, then Burson Play is going to provide an even better experience.

    Burson Play vs iDSD Micro BL - We considered iDSD Micro BL to be one of the best DAC/AMP devices we tested back when we tested it, and we even considered it to be the pinnacle of DAC/AMP technology. At that point, the title was actually well deserved by iDSD Micro BL, there was barely anything better on the market, and even if there was, it costed more than 4 times more, so we considered it fair to give iDSD Black Label the title of the pinnacle. Now, Burson Play probably won't be the pinnacle of desktop DAC/AMP technology, and we most certainly believe that the improved OP-AMPs can get it closer to this title, but when it comes to Burson Play vs iDSD Micro BL, the fight is one of the most interesting we've seen in years. As you might expect, both devices are really well built, both feel and look astonishing, and both make excellent value. Now, iDSD BL doesn't come with all the cables one needs to enjoy it, missing the OTG cable it needs to connect to a typical smartphone. Happily, iFi makes such cables now, although you have to order them with the unit, for a little price. If you plan on enjoying Burson Play with a portable source, like a smartphone or a tablet, you should order those cables for it as well, as it doesn't come with an OTG cable either, and you need one to connect it to most Android-based devices. Now, let's split the comparison to both the DAC and the AMP parts. This is because iDSD BL and Burson Play both can be used as a standalone DAC, and as a DAC/AMP. On the DAC side, iDSD BL surely features a more complex, more recent and better overall DAC Unit on paper, but as always, the implementation is the most important aspect of a DAC unit. Here, both companies have done a great job at implementing their DAC units the best they could, both DACs having extreme amounts of detail and resolution. iDSD BL has a touch more detail, but its textures are slightly smoother, with a similar depth to the sound on the DAC side. Burson Play has a slightly wider sounding DAC with more emphasis on textures and texturization. On the Amplification side, iDSD BL has somewhat more power than Burson Play, and it is a portable unit, but in sound it comes off as quite the other way around, iDSD BL being more gentle in certain areas. iDSD BL has a deeper sound, with a more realistic soundstage, while Burson Play comes off as wider, more energetic, providing a more revealing texture, although it doesn't necessarily have a better resolution on the overall level. Both devices sound very effortless, both devices have an excellent sonic performance in every way imaginable, and both are great to listen to. Areas where iDSD does better than Burson Play are also in the fact that it can be used portably, although it still isn't quite as portable as FiiO Q5 or HIDIZS DH1000, both of which are smaller and easier to match with portable devices. The other aspect where iDSD is a clear winner is in its performance with very sensitive, very low impedance In-Ears. iDSD BL is able to keep its signature consistent across all impedances, and it is able to provide a hiss-free sound due to the fact that it has the iFi tech for hiss reduction already built-in. Now, when it comes to their price, Burson Play is almost half of the price of iDSD BL in its base configuration, so Burson Play is surely lighter on the wallet, the basic differences between the two being that Burson Play has a more energetic and more textured sound, with a similar resolution as iDSD BL, while iDSD BL provides an added portability, higher power rating, and a more consistent performance, with less hiss, with very low impedance In-Ears. The choice here depends a lot on your budget and also on your usage scenario, but if you're considering iDSD BL at this point, we also suggest reading our upcoming review on xDSD from iFi as it is much smaller physically than iDSD Micro Black Label, if you wanted it for portability. As for Burson Play, we surely recommend it at its price and sonic performance, and most importantly, if you don't require to listen to it while on-the-go.

    Burson Play vs HIDIZS DH1000 - The main factor for us including this comparison is the fact that the two devices are priced similarly, so one who has around 300 USD may have to decide between the two. The package is more complete for Burson Play, with more devices being included, especially when it comes to interconnects needed for usage with their intended host devices, Burson Play being mainly a desktop device, with most of its connectors being prompted towards a Desktop computer or laptop, while DH1000 is made for a portable usage, so it is made to connect with a smartphone or music player rather than a computer. The build quality is great on both, we don't have any complaints for either device. The firmware of DH1000 could use an upgrade which made it turn off while not receiving any signal, but the same can be said for Burson Play, as both devices stay on even without any input. For Burson Play, this doesn't make much of an issue, but for DH1000 it is something you need to look out for since if it stays on at all times, it will drain its battery and it won't be ready for your next trip in time. The sound is quite a bit different. First thing you need to take into account is that while both FiiO Q5, iDSD BL Micro, and Burson Play can act like a standalone DAC, DH1000 can not. Another thing you need to take into account is the power rating. We compared Burson Play to two more expensive devices, but since DH1000 is an excellent example of a 300 USD DAC/AMP, you need to consider that for 300 USD, Burson Play has considerably more power as a DAC/AMP than most of its direct competitors, being able to drive Headphones that are considerably more power-hungry than DH1000 or most of its direct competitors can. DH1000 has a Balanced output, which Burson Play doesn't have, and DH1000 can play music from both its balanced output and its single ended output at the same time, although we still aren't quite sure if this was intended, or if it is a bug. The tonal signature is quite different, DH1000 is smoother, more relaxed, less revealing, while Burson Play makes itself remarked with a considerably better extension in the treble, a better detail level, having more resolution and more control, authority, and sounding more vivid, wider and deeper. If there is one area where DH1000 does have an advantage, that is in how it drives easy-to-drive IEMs. Burson Play has a high output impedance of 8OHM, which doesn't work quite that well with IEMs, especially with sensitive IEMs, hiss being audible with very sensitive IEMs, while DH1000 is silent in terms of hiss. Another aspect you may want to take into account, again, for IEMs, is that DH1000 doesn't change its signature with low-impedance IEMs, while Burson Play can get a tad brighter with extremely low impedance IEMs due to its relative high output impedance. Between the two, if you're going to use any IEM with the impedance above 32 OHM, or any headphone, and if you don't need a portable device, Burson Play sure looks like a dominant thing in the market, while if you only have IEMs with the impedance below 32 OHM, and if you need something portable, then DH1000 makes an interesting choice. If you have only low-impedance IEMs, but if you don't need portability, then Burson Play may still make a better choice due to its better detail and resolution, and taking into account that hiss can be silenced with iFi products, it surely doesn't seem like a bad deal, but if you need something to take on a walk, or anywhere, DH1000 instantly becomes more appealing. DH1000 also has a 2.5mm Balanced output, which Burson Play doesn't have, but at the end of the day, the two devices are quite different and this comparison shows quite well how Burson Play is such a great buy at its price of 300 USD, if you don't require to listen to it while on a walk.



    Pairing

    [​IMG]

    Burson Play + Ultrasone Signature DXP - This is one of our favorite pairings with Burson Play, as it gives Signature DXP both an excellent width for its soundstage, but also an incredible amount of energy and impact. Signature DXP is generally quite a dynamic headphone, and with Burson Play driving it is even more dynamic and impactful, which works well with their U-shaped signature. It is hard to have this setup on your head and not start headbanging even if you were just working on writing on something.

    Burson Play + Audeze LCD-MX4 - Although LCD-MX4 is Audeze's line of very portable Headphones, they still show an interesting improvement from being powered from a strong source like Burson Play. We can describe the sound as being incredibly detailed, vivid, forward, wide, very textured and incredibly dynamic. The impact of this pairing is also quite something to see for yourself, especially since we generally recommended adding a few dB's of Sub-Bass and Treble to Audeze LCD-MX4, with the control and authority the Burson Play has over their bass, this need being smaller than with most portables, like Hiby R6, where we felt LCD-MX4 needed more bass and treble.

    Burson Play + Beyerdynamic Amiron - This is another pairing you fall in love just by hearing it. Amiron is probably one of the most gentle and comfortable headphones we heard, an excellent example of a relaxing headphone you can simply lean back with and forget about anything that was bothering you before plugging them in. The pairing provides a bit more width, to Amiron's already nice depth, and it also provides a slightly more textured sound, making Amiron feel even more dynamic.

    Burson Play + Sennheiser IE800 - Sennheiser IE800 is an interesting IEM because although it has a pretty low impedance and high efficiency, it surely isn't affected much by hiss nor by Burson Play's rather high output impedance. The sound is as interesting as IE800's sound always is, dynamic, well separated, well layered, detailed, with a strong and well-controlled bass, sparkly treble, and clear midrange. Everything feels in its place, and as a bonus, the sound is wider than IE800's sound usually is, and it also feels more dynamic than it usually does.


    Burson Play + iBasso IT04 - While our review on IT04 is still on the way, we want to give you a little peek on how it sounds like. It is a natural and well-balanced IEM, with a touch more sparkle in the treble than what would be dead neutral, it has a very quick sound with an excellent PRaT, and they sound very wide in their soundstage, especially compared to most IEMs in their price range. Although they are very open-sounding, they do isolate very well and leak very little, making them an excellent choice for on-the-go listening, or for blasting death metal while reading obscure books in a library. When it comes to their pairing, Burson Play does show some hiss with IT04, and the sound has slightly less bass than with most other source, but they also gain a very quick impulse response, an even wider soundstage than they usually have, and they also sound considerably more impactful than they usually do. Quite an excellent pairing on the overall level, if you're not bothered by hiss, although that can easily be solved by adding an iFi iEMatch to the setup.



    Value and Conclusion

    We reached the end of our review, and we have to say, Burson Play has been one heck of a device to listen to and review. We also still need to review the higher-end OP-AMP for it, as soon as we can get our hands on a pair.

    [​IMG]

    Burson Play is priced at roughly 300 USD in most places of the world, which is quite an interesting price point. Fighting is intense at this price point for most Headphones and In-Ears, but most portable players from the high-end area are priced higher, while most entry-level ones are priced lower. This doesn't mean that Burson Play doesn't have a lot of devices it needs to overcome in this price, and quite on the contrary, since it is a desktop device, it needs to bring something more than more expensive portables do, to justify its price.

    Starting with the build quality, we have a medium-sized device made entirely out of metal. It doesn't just look like a tank, it is a tank. You'd have a very hard time doing anything to it, the casing is made out of thick metal, and it is one of the best we've seen to date. Not to mention that its volume wheel is also well designed, and all jacks are tight and well fit, so you really would have a hard time not giving it a golden rating for its build quality.


    [​IMG]

    The firmware is as solid as it can be, it never crashes nor disconnects, being one of the most stable devices we've tested to date.

    If anything physical about it should be mentioned as a negative, that is that it gets quite warm physically, while in usage, especially important if you're going to be using it inside a desktop build, as you will need to have a fan pointing to it to keep it cool.

    The sound is as impressive as one would expect from a company as renowned as Burson, it is very vivid, dynamic, punchy and has an excellent resolution for 300 USD. Most important, it has a lot of power, and an excellent authority and control over anything connected to it. The only downside is that it has a bit of hiss with In-Ears, and it has a slightly high output impedance, so it doesn't match quite that linearly with In-Ears, but this isn't a big issue, and we had an excellent time using Burson Play with Sennheiser IE800 and iBasso IT04.


    [​IMG]

    All in all, if you're looking for an excellent desktop DAC/AMP, which can provide lots of enjoyment for you, both through headphones, or even acting as a desktop-grade DAC, Bursin Play makes a very compelling purchase, and not only it will drive your High-End Audeze Headphones, but it will also do it with an excellent degree of authortiy and control, providing what we consider an excellent overall experience.

    All About That Bass
    Written by Mij-Van
    Published Jun 10, 2018
    5.0/5,
    Pros - Power and muscle.
    Cons - No real line-out. Matt finish case.
    This is a review of Burson Play Basic.

    Long time lurker here, I’ve learned quite a lot from reading on HeadFi and comparing reviews with my personal impressions. Therefore I was quite delighted when the fellow HeadFier @DjBobby lent me the Play for 2 weeks to test it. I wouldn’t like to repeat the specs and technicalities which are stated and reprinted in almost every review, but focus more on my personal observances.

    Trivia
    The Burson Play doesn’t have serial number. It can be used in the PC case or on the desktop with 4 adhesive silicone rubber feet attached. It comes with high quality RCA audio cable, actually two of them. You get one mono cable for each channel of aprox. 55 cm lenghth, which is very convenient for desktop use. Connecting headphones doesn’t mute the pre-out. It get's quite warm. The case in matt-metallic finish isn’t quite ideal, being a magnet for dust and fingerprints.

    Although in the Qobuz online review it was stated that the Play doesn’t work with IOS devices - it does. You can read the review with a help of Google translate here:
    https://www.qobuz.com/be-fr/info/hi-fi/bancs-d-essai/burson-audio-dac-play-v5i-un-petit180626
    I’ve tested it with all my iDevices and it worked without any problem. Using hi-rez audio on both Onkyo HF and Dan Leer’s Flac player, the Play had absolutely no issues, so I can’t understand why didn't the Qobuz team make it. What I didn’t get was playing DSD256 files. DSD64 and DSD128 had no issues but with DSD256 it always switched to PCM352.8 Khz.

    Sound impressions
    I am late 20’s music lover with special affinity for double bass, meaning I am listening predominantly to deep but clear bass sound. Not only the bass of course, but this is very tricky area for many dacs. Quite often you get just rumbling, double bass sounding like moving the furniture around your house and it is not easy to follow the pitch. Listening to the same recordings on the vinyl gives you mostly better pitch control, more layering and better instrument separation.
    The music I was using was the album „London Double Bass Sound“ feat. Gary Karr, „From Kirk to Nat“ with Rufus Reid, Miles Davis’ „E.S.P.“ with Ron Carter and a bunch of other pop, electronic and some classical music. Listening was done mostly with the Senns HD25 and HD598.

    All About That Bass:
    Short version - this is one of the best bass performances I’ve ever heard from the dac/amp combo. It’s punchy, clear, meaty, juicy, you name it. It was a joy listening over and over again through old recordings sounding being juiced up. The timbre was there, the pitch was easy to follow and and there was an overall authority to the low bass sound. The instrument placement was very realistic and palpable with lot of spatial information. Interestingly even on Senns which are already on the dark side, the Play never sounded mudded. There was richness to the upper mid-bass with nice transition to the lower mids.

    Mids
    The lower mids were very rich sounding, almost euphonic and tube like, with nice color to the lower male voices. Going higher up it started to sound somewhat grainier and slightly rougher and there were times I was thinking about how better opamps would have contributed here.

    Treble
    Very detailed and with lot of sparkle, maybe sometimes too much sparkle. On certain bad mastered recordings the treble sounded thin and acidic, with Sabre glare coming clearly through. Again maybe different opamps would have mellowed the treble.

    Soundstage
    The soundstage is wide and moderately deep, with instruments sounding somewhat distant. It works great with big orchestral music. With some simpler acoustic music like Nora Jones, I would have wished being closer to the stage. Or the musicians closer to me.

    Conclusion:
    For $299 for the basic version, you can hardly get the cheapest Chinese no name dac/amp combo. If you find it, it still would be no comparison to Burson's excellent build quality and a 5 yr guarantee. It’s all about that bass and that bass is great. No brainer 5 stars.

    Burson Play - one extremely versatile DAC/Amp !
    Written by Wiljen
    Published May 20, 2018
    4.5/5,
    Pros - Very Versatile DAC/AMP with good power and tuning opportunities
    Cons - USB Only, no optical or coaxial inputs, AC adapter not as robust as rest of unit.
    I was loaned the Burson Play as part of the review tour and would like to extend a very heartfelt thanks to the crew at Burson Audio who really went above and beyond the call to make sure we had a working unit for the tour. I won’t elaborate here, suffice it to say other organizations might have decided to end the tour early rather than go through hoops to make it happen but Burson stuck with it and sent out another unit to finish the tour.

    The Play is an interesting critter. On the surface, it can be seen as an entry level DAC/AMP since at the heart of it, that is what it is. Beyond that, the Play is designed to fit in a PC bay normally reserved for a CD Rom drive. In PC speak, the Play fits in a standard ½ height 5 ¼ inch drive bay. The upside being, most full-sized desktop and tower configuration PCs have at least one available bay of this variety. The downside, is maybe not for much longer as direct download of software and use of USB drives have all but hammered the last nail in the coffin of the CD. Because of its design, the Play has both a connection for an AC adapter and a 4 pin Molex connector again designed for a standard CD power connector (12 and 5V DC power). I did not mount the play in my PC during the review tour but did use a 650-Watt PC power supply instead of the provided AC adapter for a good bit of the testing to simulate PC use.


    Packaging:
    The play came shipped in a well labeled black box that while subtle, conveyed the needed details. Upon opening the box, two smaller boxes surround the main unit which sits in the center. The boxes contain the power brick and connecting cables as well as adapters for use of the play inside a PC case. Overall, nothing fancy about the packaging but nothing left lacking either. Well packed for travel and a good set of accessories and tools needed to mount the unit either as a standalone or inside a PC case. The unit also sports a stick remote which comes in handy as raising or lowering the volume in large increments is easier with the remote than the dial.


    Build:
    The front of the unit has a 6.3mm jack for headphones, a 3.5mm jack for a microphone, a two-digit numeric display built into the face plate, and a large volume knob. The volume display is extremely well done with cutting the holes through the metal face rather than simply exposing the entire component. Some will complain about it being too bright for bedroom use but for most gamers who tend to adorn PCs with neon anyway, I suspect no such quarrels will be heard.

    front.jpg


    A hex head screw adorns each corner of the case front and rear and allows for near complete disassembly of the unit in very rapid fashion if desired. It should be noted that while the front and rear screws are the same thread pattern and take the same Allen wrench (provided in the accessory kit) that the heads are enough different between front and rear that they need to be kept separate when taking the cover off the unit.

    screws.jpg


    The top cover is keyed so it cannot be installed backward as shown below, and tolerances are very tight so careful alignment is needed to get the unit back together.

    rail1.jpg rail2.jpg

    The rear of the unit is a bit busier than the front with a USB input on the far left, then the AC input, the 4 pin Molex DC input, a power switch, and a pair of RCA pre-outs at the far right.

    rear.jpg

    The sides have screw holes placed at the appropriate locations for mounting the unit while the top and bottom are solid metal painted a nicely subdued flat black.
    side.jpg

    The paint job is susceptible to scratches so once used inside a PC case, the unit will likely sport a few battle scars and may need to be repainted if you later decide to use it as a stand-alone.

    The unit is designed to be opened by the end user as changing op-amps is not only possible but expected. The good news is sockets are well spaced to make replacement of op-amps very easy to do without having to worry about bumping a cap or resistor in the process.
    sockets.jpg


    A diagram on the inside of the top cover shows clearly the proper orientation of the 5 replaceable op amps (3 doubles for the DAC side and 2 singles for the headphone amp).

    PlayInternals.jpg


    This is critical as mounting an opamp backwards not only wont work, it has potential to destroy the op-amp and the unit. My advice is take photos before removing the existing op-amps the play ships with. Be certain that all photos clearly show the proper orientation of the op-amp in the socket and have enough detail of the area around the socket to clearly identify each one. Once you have the new op-amps installed, compare to the photos just to make certain all alignments are correct before powering on. This helps prevent mishaps. (As a side note, when using the V6 Burson op-amps, the three doubles should have the label facing away from the center of the unit and the two singles should have the labels pointed toward the rear of the unit. When using the V5i, you have to watch the U notch placement as label orientation is less helpful as a reference since it is on top of the unit.)

    classicfront.jpg classicback.jpg withadapter.jpg withoutadapter.jpg

    The AC Adapter is probably the weakest link in the build as it is a standard laptop style brick with a barrel connector. Some conversion has to occur inside the unit as the power supply is only capable of 12V at 5A. While I understand use of this component as a cost saving measure and it worked fine (as did the 650 Watt PC supply I used to test), it is clearly not aesthetically of the same quality as the rest of the unit and appears to have been a bit of an afterthought.

    When using inside a PC case, make sure the Power supply can handle the additional draw the Play will demand. The AC Adapter is capable of providing 60 watts so that is a realistic estimate of what needs to be available from a PC power supply in addition to the other demands placed on it. Most gaming rigs have pretty hefty power supplies and should handle the play with ease. Small desktop PCs designed for office use probably will need an upgraded power supply to handle the addition of the Play to the case.


    Sound:
    The play came with V6 Classic Opamps installed in both the DAC and pre-amp sections and a pair of V6 Vivid Singles for use in the pre-amp stage. I had previously tested the Burson V6 and V5i and found my preference to be for the V6v for rock and blues rock and the V6c to be better suited to Jazz and vocal pieces where the extra energy of the vivid was a bit over the top for me. For that reason, I did my testing first with the unit as it arrived (V6 Classics in all slots). I then went back and replaced the two single op-amps in the output stage with the V6 vivids and did my listening tests for a 2nd time.

    In order to test the sound of the DAC independently of the built in amp, I used the pre-outs to connect to my Asgard2 and a first generation Valhalla. I then listened to all the same selections using the Asgard2, the Valhalla, and the internal Amplifier of the Play using several different provided Op-amps. (I wrote up the Burson Op-amps previously here).

    File types supported natively include all the expected varieties (FLAC, ape, etc…) at up to 384kHz and 32 bit depth. DSD is supported at 64,128, and 256 both natively and as DSD over PCM if desired.

    The play has good extension on both ends with good slam and authority in the bass and sub-bass with both the Classic and Vivids. I don’t see the Play as being bass-forward but did find that use of the Burson V6 Vivid op-amps did add a bit of coloration to the bass. Mids are well rendered on both sets of op-amps but are a bit more forward on the Classic than the Vivid. Treble sparkle is a bit more pronounced on the Vivid but both have good extension and air. I cannot fault the extension on either end with either set of the op-amps but can say conclusively that both add a bit of their own color to the sound.

    The Classics deliver an intimate sound stage with great separation and really fantastic imaging that is best seen on small ensemble pieces. I can see where this would be a great choice for gaming as the imaging really is spot on. Even audience noise appears to come from the opposite direction as the instrumentation which is quite a feat. Instrument separation is good on both but better on the Vivid which handles large ensemble pieces and exceptionally busy pieces with a bit more aplomb than the Classics.

    The play also handled busy tracks without getting muddy or thick and was able to maintain realistic timbre for both bass guitar and vocals (particularly so with the Vivids) which can be difficult to do. In the overall, I found the Play to be at least as good as any other DAC I have in the house at the moment. (Mojo, Bifrost, Audio-GD). Overall, an impressive showing for a $549 setup.

    I expected to find more differences than I did between the internal amplifier of the Play and the Asgard2 or the Valhalla external amps as having read the specs for the Play I was a bit concerned that output power dropped pretty radically as impedance went up. I was particularly puzzled by the listed 8 Ohm output impedance of the headphone jack on the play which would, under accepted theory, suggest a minimum headphone impedance of 64 Ohm combined with a power output curve that was obviously geared toward headphones 50 Ohms and under. It has since been pointed out that measured values show the output impedance at <1 Ohm when using 32 Ohm headphones which makes much more sense so this is probably simply a matter of documentation needing an update on Burson's site. Again, this is not a criticism necessarily as a quick survey of headphones aimed at the Gaming market found nothing over about 32 Ohm. The Play has more than enough power to drive anything under 300 Ohm and handled Oppo and Fostex planars without any problems. I also found it odd that the advertising for the Play all shows it with a volume set to 89. I suspect this was more to highlight the display than anything as even with notoriously power-hungry cans like the Fostex T50rp a volume setting of anything over 40 is going to do hearing damage and 89 is going to rupture your eardrums and cause brain bleeds in short order. I absolutely recommend you never set the Play at any volume above 20 before putting on your headphones and adjusting once you know what the output level is.

    The 00 to 99 granularity of the Play’s volume control is nice to have but makes large adjustments a slow process as it can take several turns of the knob to dial in the desired level. The remote control is faster for doing large adjustments as one can simply hold the down arrow and not have to twist the knob repeatedly to accomplish the same adjustment.

    Comparisons:
    I currently own a Bifrost/Asgard combo and can say without doubt that I could trade both units for the play and never miss either of them.

    While the play lacks the portability of the Mojo, it has better mids and delivers more power to hungry cans. This is a tough comparison as the two form factors are so different. On sound alone, the play is better.

    When compared to the Modi 2 /Magni 2 uber I use at the office, I can say again that the Play would make an equally compact and more versatile solution with the only downfall being a slightly lower output power. Since most of us don’t use our ultra power-hungry planars at the office anyway, I’m not sure that loss would even be noticed.

    Conclusions:
    If you want a small package capable of big things, you would be hard pressed to find a better way to spend your money than the Play. The Play offers more customization options than any of the other single units available at anywhere near its price point and offers the budget conscious a way to buy in stages.

    For those on a tight budget, the $299 entry price provides a great starting point and then as funds avail themselves one can add the Classics or Vivids (or dare I say Muses, Burr-brown, or someone else’s op-amps) to alter the signature as desired. Stepping up to $399 you get the V5i throughout which offers 95% of the performance of the fully discrete op-amps at 73% of the price. It is hard to argue with the math on that and would be the configuration I purchased if in the market today. For many, it will be an end-game PC sound system with fantastic dynamics, staging, and imaging for gaming as well as audio. For those where audio is above all else, they will find either the V6 Classic or the V6 Vivid (or some of both) to be to their liking and again, for the $549 asking price, It would be tough to find a better value. For those who haven’t yet played with a Burson product, I highly recommend you take this one out for an audition. Somewhere between the base model and the V6 Classics, you are bound to find a sound you like.

      When used with 32-ohms headphones, PLAY's output impedance is <1-ohm (feel free to measure by yourself); probably when using 8-ohms cans the output impedance would be much higher! Also, don't forget there're no resistors or capacitors in signal path at the output of the output stage, there're just the output transistors and the protective relay.

      Probably just a case of Burson needs to update the verbiage as it didnt seem likely that those figures fit.
