Yes, can be used as DAC only, has a line out. You need cable with 3.5mm on Xduoo side and then check the Atom inputs to see what cable end is needed for the Atom. Is decent DAC, no distortion.

Hi thanks. i just bought a topping l50 amp, which on paper has way more power. However, with my Dt770 250 ohm, I am able to get more volume (albeit with more distortion) out of the xduoo xd diretcly compared to plugging it into topping l50 with xduoo as dac. there is not distortion, but i was hoping for more volume considering the stats. Could it be that the xduoo xd 05 is not outputting enough voltage out the back?

Hello.

i just bought a topping l50 amp, which on paper has way more power.

Says 2800mW at 32ohm.

However, with my Dt770 250 ohm, I am able to get more volume (albeit with more distortion) out of the xduoo xd diretcly compared to plugging it into topping l50 with xduoo as dac.

Which should not be happening. Are you sure you connect the Topping to the line out jack of the Xduoo ? The far left jack here on the image - AUX In/Out.

there is not distortion, but i was hoping for more volume considering the stats.

I mean you are right, if this Topping is 2800mW, it will be louder than any portable Xduoo anyway, even if the line out voltage of the Xduoo is not a lot. I was thinking you maybe have the Xduoo XD05 the basic model, not the Plus model. And for the headphone out it is 500mW the basic vs 1000mW for the Plus (no official details for the line out voltage when used as DAC, i think is somewhere between 1.5 and 1.8v). In any case the Topping is much more than any of them, so what you experience is very strange. I don't know what to advice other than to check if the volume on your software player, which you have the Xduoo connected to use as DAC (PC, Tablet, Phone or so, check the volume settings on it).

You could check the Topping amplifier, how behave when you connect it to some other device you have. Just for the test, does it get very loud with these same headphones if you try connect it to PC, Phone, Tablet or something like that.

Also the Topping might have a lot power only with balanced type connection and not single ended. They make them so these days. But i saw it says 2800 single ended, not balanced. Very strange the whole thing man. But check the software player and if you are using the line out jack at the back of the Xduoo for connecting to the Topping (and not the front jack for the headphones).

Hi Thanks for the reply.

I have it connected to line out. I have the xduoo xd-05 original, which is now the basic one. I mean with the xduoo, anything past 3 o clock the music just turns to noise on my dt 770 ohms. With the topping L50 I can push it to max no distortion, I guess i was expecting my eardrums to be blown and inability to push the knob past 3 on high gain. Topping does provide clean power all throughougout, however the volume at max is the same as xduoo at 3 o clock albeit with much more distortion. I think it is the line out voltage for sure, its probably 1.5v. I am gonna try plugging into my laptop or playstation 5 controller using aux to rca cables.

Atleast, I can now tell that the xduoo is in adequate for my dt 770s. They bring out so much detail and clarity and soundstage with the L50, with the xduoo xd 05 everything was mushed together.

I ordered a topping e50 dac now... damn and balanced cables for the interconnect. This hobby is expensive.


edit: I think the amp has "opened up" with use, getting more juice now & when I plug it in directly to he laptop using aux out, I get even more volume although more hiss and distortion.

Hi everybody. I m going to buy Xd05 bal today. Im going to use it with iems ( my best iems are Solaris Og and Mest Mk2) and on headphones ( waiting Hifiman XS). I like detailed sound. Could you show me a little description of opamps ? V5, Muse02 and AD827SQ thanks. And if someone use Ifi Gryphon, what do you prefer, XD05 bal or Gryphon? Thankssss

 

[Gustavo1976]

Hello everyone! It's been awhile since I've posted an opamp review here, but I finally got my hands on another opamp that pairs well with the XD-05+ and wanted to share. Some time ago I ran subjective tests on 43 different opamps in the XD-05+ (42 at once, and another later on). Since that point I've been happily enjoying the XD-05+ with an AD827SQ as my favorite, but I've always been curious about some of the other higher end op amps out there. The two I've been most curious about are the Burson V6 Classic & V6 Vivid. I didn't try them before as I knew they wouldn't fit in the XD-05+ case, but it never stopped me from being curious. Well, fast forward to now and I finally have my hands on a V6 Vivid (no V6 Classic just yet).

V6 Vivid with an extension lead. The capacitor next to the opamp slot blocks the V6 from being able to sit flush. Only options are to either relocate the capacitor, use multiple adapters to raise opamp slot, or use an extension:


Below are comparisons to some of the other top performers in the XD-05+:

Burson V5i
The V5i is a top contender for being one of the best opamps in the XD-05+. If you read the entire thread you'll find it's the thread favorite, being almost universally praised for improving the sound over the stock op amp. Compared to the V6, The V6 is significantly clearer than the V5i. I wouldn't consider the V5i to be dark or muffled, it's closer to clear than dark, but it does end up sounding more congested and muted compared to the V6. Clearer doesn't mean brighter here, as the V6 also has more fullness on each note. On the V5i that fullness is replaced with a little sharpness. The V6 also has a minor amount more stage width, similar depth, clearer separation, more note impact, additional detail, and improved bass control. Basically it's an upgrade across the board.If you like the overall V5i sound and want further improvements and fixes, then the V6 is a definite upgrade. Of course, if you don't want to modify your XD-05 in any way, the V5i is still in the top tier for the XD-05+.

AD827SQ:
The AD827SQ has been my favorite op amp for quite some time, and has been my top recommendation for a neutral op amp in the XD-05+. Comparisons here get more complex and are more subtle than other tests so I'm listing them out below:

• V6 is moderately clearer sounding vs the AD827SQ. In direct comparisons the 827SQ has a warmer sound. The V6 doesn't sound brighter, just clearer with the same overall note timbre.
• Both the V6 and 827SQ have the same bass quantity, but the slam is slightly improved on the V6 due to the clearer presentation.
• The 827SQ is more airy, but the V6 has improved note placement and each note is fuller sounding. This leads to an interesting situation where the 827SQ gets more micro detail due to hearing each sound expanded in a diffused way, but at the same time the V6 has more micro detail due to how precise & full each note sounds. All things considered, the V6 has more perceived detail.
• V6 has a slightly wider sound stage
• V6 has better instrument separation despite not being as airy.
• 827SQ has a bit more treble extension. The V6 isn't soft in treble, but it doesn't have as much of an edge on each note.
• V6 has significantly more impact on each note, wheras the 827SQ is more laid back.

In an overall comparison the 827SQ and V6 are quite close in overall sound quality, but the V6 is more refined. The AD827 sounds wonderful, but I do prefer the V6 due to the increased dynamics, clearer presentation (which I typically prefer over added warmth), and improved stage.

Muses02:
The Muses02 is similar in tonality to the V6, both having a clear presentation with great note impact. Instrument separation is also similar, with the V6 having a little clearer separation. Where the Muses02 falters is a moderate amount of compression compared to the V6. This leads to a reduction in sound stage width, squishes notes a little, and reduces overall detail. Despite this the Muses02 still retains a mostly holographic sound. The Muses02 is also leaner, with less fullness on each note and a slightly elevated treble. This combination pushes the op amp a little closer to a U shaped sound. With this leaner sound the Muses02 ends up with slightly more impact on each note compared to the V6. Overall the V6 shares a similar clear tone but with much less compression, more stage, and a generally fuller more neutral sound all around.

Muses03:
The Muses03 has a much more up front presentation when compared to the more holographic sounding V6. It's about the same overall sound as a Muses02 with stage depth reduced, less compression, fullness is increased, and the tonality is lowered to lower than neutral. Stage depth on the Muses03 is small, but the width is excellent. The V6 has more depth, and is very similar in width. In prior testing I found that the Muses03 had the largest stage width of all the opamps I tried on the XD-05+, so the V6 shares the top spot there. Details are similar, but the Muses03 has a little less partly due to a subtle softness on each note. The V6 also once again has more fullness in each note, which further improves detail over the Muses03. The V6 has a correct clear presentation to it, wheras the Muses03 has a rolled treble response that pushes it a little lower than neutral. The Muses03 still sounds great with it's great stage width and details, but the V6 ends up besting it.


Summary:
TL;DR is that in my opinion the V6 vivid is the most complete sounding op amp of all the 44 op amps I've tried. It's typically the top performer in each sound category, and in cases where another op amp is better in some aspect the V6 is still a top contender. The V6 Vivid takes the clear tonality of the Muses02, sound stage width of the Muses03, depth of the V5i, bass quality from the 827SQ, and note timbre from the 827SQ. Take that package and add in the best detail, note placement, separation, and holographic sound of all the op amps I've compared. Finally sprinkle in great dynamics on every note. Overall the V6 has the best qualities from the top performing op amps in the XD-05+ without including their drawbacks.

The Elephant in the Room:
The V6 is big, too big for the XD-05+. I looked around in the case to see if I could relocate any capacitors to make it fit somewhere, but I'm not seeing any immediate solutions. The only good options I can see are to either keep the case open (like in my screenshot above) for desktop only use, or cut a square above the opamp portion of the case and cover the opamp with something sturdy and non-conductive. One such creative setup was posted here by Vannak. I'm personally thinking of cutting the case then attaching a top plastic piece from a vending machine toy (you know.. those rounded clear plastic bubble containers that have a toy inside). In the end my XD-05+ would look like a Jetsons car, but the sound would be worth it

Could I put two opamps like Burson V5i and Muse 02? Im waiting for Xduoo and opamps. I bought Burson V5i, Muse 02, Muse 8920, Ad827AQ.

The XD-05+ supports installing one dual op amp (Muses02, 8920, 827AQ), or two single op amps. Some op amps have both single and dual versions, like the Burson V5i. I don't know for sure what would happen if you tried to install two duals, but I assume it would fry the op amps immediately. I also wouldn't recommend putting two different single op amps into the XD-05+ as that's probably just asking for trouble.

Stock opamp are two single on Xd duoo xd05 bal. I bought one dual Channel Burson V5i. I have to quit two stock and put the burson v5i. Ok??

I received a Burson V5iD from John, to try with my Xduoo XD-05 Plus in exchange for an honest opinion.

I think he sent it to me between late October and early November.

Since we are in late January, I thought the package had been lost and I no longer hoped for it, but surprisingly just last week it was delivered to me.

Short cut and I immediately say that with the Sennheiser HD 600 it is by far the best match.

With the opamp stock the sound is too dark and with little resolution, with the AD827SQ the resolution increases significantly but there is something wrong with the mids, mids-treble that in the HD 600 are already forward, carried further forward. The result is not very pleasant and rather tiring to listen.

With the Burson V5iD I get an absolutely good and balanced sound to my ears, slightly warm, smooth, with the right weight and a much better resolution than the stock.

My main concern after reading reviews here on the thread was about the bass, I was afraid they might be a little boomy and out of control, but luckily I can say I have no problem with the bass.

They're a bit more than neutral in quantity, but absolutely adorable and with the HD 600s he felt was missing something right on the bass they work perfectly.

I have been listening to XD-05 Plus with Burson V5iD for only 4-5 days, with further "critical" and attentive listening I might also notice some small flaws, but at the moment I am 100% satisfied with this new pairing.

I will update with more impressions and some photos.

Thanks. Waiting for V5i. You put two opamps obviously.

Been listening to the xd05 plus for a few weeks now. Paired with the DCA Aeon open x. I really enjoy the sound stock. However I received a Burson v5i D yesterday. Just installed it and can say that it sends this already good sounding amp to another level. Way more open, airy and detailed with a much better soundstage. I bought directly from Burson for $64 total. I ordered it on Monday and received on Thursday. Money well spent.

 

[sebek]

I'm listening to a Sennheiser HD 6XX with XD-05 Plus and Burson V5i-D, really nice sound. Full, detailed, musical, with a nice soundstage and good punch.

The Burson V5i-D is indeed a huge upgrade for the Xduoo XD-05 Plus over the stock, and at least with my headphones it sounds better and more convincing than the AD827SQ.

Chord Mojo I think is more refined overall and with a more relaxed sound, but that can get a little too lazy at times.

Thanks again to @John Burson for giving me the chance to try the Burson V5i-D.

One question: with high impedance headphones, 300 ohms and above, do you activate the Boost?

It makes the sound a little smoother and fuller and less dry to my ears.

 

[sebek]

The weak point of the stock opamp is definitely the resolution, and I don't think I would recommend it in its stock format, there are probably alternatives with less driving power but better sound quality in the price range.

It is a pitch black sound, with a very vague image and little detail.

With Burson - but also with AD827SQ - the improvement is evident. It turns into a really great device, which depending on the combination can compete with more expensive products.

Bass boost with HD6XX was not so great for me as it changed the sound signature and made already warm and thick sound even more warmer and thicker. If you prefer that kind of signature, you are going to like it. If not, you better keep it off.

I liked the bass boost with Ananda than with HD6XX and LCD2C. It made Ananda sound just the way I wanted.

The Xbass II on xCan is better than the bass boost on XD-05+ IMO as it doesn't change the sound signature.
