    "Another hit by theBit"
    Pros - design, price, sound, UI, firmware
    Cons - wiggling volume wheel, but it's not really an issue
    Looks like theBit have decided to become a king of the hill, or at least join those who are already standing on the top. After the first successful skill test (I mean OPUS#1) they've come back with really flagship OPUS#2 model that can be considered as one of the TOTL solutions. And now, theBit strengthen their position with great OPUS#3.
    1-Main Pic.jpg

    First of all, I'd like to thank theBit for providing me a sample in exchange for my honest and unbiased opinion.

    I'll shorten my work and won't go deep into describing OPUS#3 package, accessories set and overall design. There are few stellar reviews done by fellow Head-Fiers, you've read them, and I don't have much to add to them.
    2-Box.jpg

    The package is simple and stylish; DAP looks interesting and fresh, it feels solidly built and operates smoothly. There is a little wiggling of volume wheel, but it's still doing its job flawlessly (better than one on my AK320 actually). Firmware is rock-solid, as usual for theBit products, and recently added wireless streaming applications are an excellent addendum. Well, this time looks like I was brief in sharing my impressions, so, let's move on to the sound.
    3-Accessories.jpg

    First of all, I'd like to mention that my feelings on OPUS's general representation slightly differs from other reviewers. I'm not sure what it the reason, maybe it's a subjective perception, perhaps there is some other reason, who knows. Personally, I don't found OPUS#3 sounding very neutral or bright. There is a small accent on treble, but it's not enough to call it bright. Also, there is a slight hint of added warmth on lows, so for me, OPUS#3 has a bit of "fun" sounding coloration, but without sounding colored or non-natural, because accents are subtle.
    4-Rear Side.jpg

    The bass is very, very slightly accented to create a slight effect of warmth. A speed of lows is slightly reduced to make the sound more massive, but it's done very neatly, without making sound bloaty or muddy. The player is superb in texturing and instruments separation in the low-frequency range. Sub-bass is present, but it is slightly reduced quantitatively, to avoid muddy sounding on the LF.
    5-Wild Garlic.jpg

    The mid frequencies are transparent and slightly emphasized regarding emotionality. Sometimes it seems that the player especially highlights the vocals and adds emotions in the vocal. With OPUS # 3 it is very pleasant to listen to classic bluesmen, favorite jazz singers, emotional rockers. Naturally, the player is right at the resolution, but it does not go into sharp, dry sounding, and does not try to pull out all the tiny nuances from the record. On the contrary, it can even sometimes hide some mastering/recording flaws. The imaginary stage is very wide, but without further inflation, the depth is bigger than average, but not as record-breaking as the width. The separation of layers is magnificent, especially due to the emphasis on vocals.
    6-Again Rear Side.jpg

    HF "in general" are good, detailed enough and have splendid decays. Sometimes, rarely, OPUS adds too much energy to treble attacks and can cause a bit sharper sound than intended, but with appropriate headphones, it won't be an issue. Also, this problem seems to be less pronounced in the DSP mode of XMOS, although the difference is small and can be attributed to the placebo effect.

    Few quick comparisons

    theBit OPUS#1 The first OPUS sometimes loves to "inflate" the imaginary stage, it gives a spectacular, but not always natural sound. Also, OPUS#1 sounds more neutral and has slightly drier representation. OPUS#3 does not try to exaggerate the stage, representing it as it is, and in general, the player sounds a little darker and more vigorous. Plus OPUS#3 has a darker "background."

    theBit OPUS#2 The primary task of the flagship is to sound as neutral as possible, without going too dull, and the "second OPUS" is doing that well. He's less accenting emotions (although he's flawlessly showing what is present in the recording), he has a deeper bass and better in layering. Treble is a bit better too. Although in fact, the difference between #2 and #3 is not that significant (less than between #3 and #1), but the feeling of "step forward" is present.

    iBasso DX200 Quite the opposite of OPUS #3, iBasso is neutral, not colored, with maximum resolution and detalisation. The main problem of the iBasso player is a pickiness to the quality of the recording. Opus in this respect is more tolerant, and his presentation is more emotional but slightly less resolving.

    Fiio X7 + AM2 In general, the representation of these players can with a little stretch be called similar, but in fact, there is a noticeable difference in the accents - the Fiio player is slightly less sharp on the HF and somewhat simpler in the mid range.

    Fiio X5-3 Not quite a competitor for OPUS#3, but since the model is popular, I can not ignore it. The newcomer from Fiio is just an even greater deviation in the direction that Opus only hints. X5-3 has more warmth in the sound, relaxed HF, everything that is necessary to create a "comfortable" sound.
    7-Screen.jpg

    Compatibility
    OPUS#3 isn't super-powerful, it shows very reasonable approach, allowing battery saving and background noise reduction. Player's power is more than enough for almost all IEMs and reasonably tough full-size cans. I've tried lots of IEMs, but best results I've got with Ambient Acoustics LAM7 (customs from Kiev laboratory) and Noble Kaiser Encore. Of the more affordable models, I can mention Dunu's hybrids and new Periodic Audio Beryllium IEMs.
    8-Knob.jpg

    So, to summarize — theBit made a balanced player with good sound, beautiful design, and great ergonomics. They've chosen right niche and select competitive price (best price I've seen are offered by MusicTeck). IMHO, now theBit is the strongest A&K competitor.

    P.S. As usual, I have an initial impressions video for this excellent DAP

    Sound
    The Opus#3 was burned in for over 150 hours to satisfy the burn in fans and the rest say it doesnt matter, so everyone is a winner.
    I used mostly 16/44 FLAC and also some more hi res tracks. Mostly I used shuffle mode as I like the unexpected tracks when testing as it keeps me on my toes and also means I listen to tracks I would otherwise skip over.
    I tested the Opus#3 in a variety of situations, at home, on the train, walking, cafes etc.
    Many different earphones and cables were used during the listening and testing period, some of them pictured in the various rig photos to give me a sense of the true Opus#3 sound.

    Opus#3 and Simgot EN700 Bass

    I usually write quite a bit about Daps I review but feel I can use a bit more brevity when talking about the Opus#3.

    The Opus#3 is a a Dap that fits within its asking price quite comfortably, perhaps due to its many functions.
    The sound is a clean, natural and accurate signature.

    I find I enjoy the 1ohm balanced port more than the 2ohm single ended port. Its more accurate, has more control and cleaner for my many multi driver IEMs.
    the smoothness of the extra ohm on the single end would appeal to many who intend to pair the Opus#3 with sub $500 or so earphones.

    At no time did I feel the Opus#3 to be lacking in general terms of resolution or power. Whilst not a super beast in terms of amplifying power it is more than enough for its intended portable use.

    With a UI that is easy to use, lightweight within ones hand and a sensible size i was quite taken with the Opus#3.

    Its tonality is like the eye of Sauron.

    Opus#3 and Campfire Audio Vegas


    The specs reveal the Opus#3 to be similar generally to the Opus#1 (not taking into account the added bells and whistles, wifi etc)
    .
    But is the sonic performance the same?

    I connected the Opus#1 and Opus#3 to a headphone switcher and volume tested them with a SPL app to get a near enough matching volume level to try to discern the differences.

    [​IMG]

    I found the Opus#3 to be more resolving overall.
    The Opus#1 has a vocals forward signature at ordinary volumes, whereas with the Opus#3 seems the music is up with the vocals, making the sound more engaging and richer and there is more definition.

    The sound stage on the Opus#3 is much larger than on Opus#1, on height and width. Making the Opus#3 more exciting, intimate and engaging. But its incremental and not absolute.
    The Opus#3 sound stage is increased in the width, slightly in the height whilst not much more in the depth.
    The sound stage increases when using the balanced out, as does instrument separation.
    They both retain the characteristic smoothness of the Opus brand, more so when using the 2ohm single ended out, things get a bit more apart when using the balanced out.
    Instrument separation is cleaner on the Opus#3.

    When I turn up the volume louder the Opus#3 seems to cope better with it.

    In summary, its very close to call in terms of sonics but the Opus#3 just pulls ahead on the single end, and more so on the balanced out.
    In terms of extended listening sessions I would pick the Opus#3 over the Opus#1.

    The Burr-Brown dac just adding that extra little something.

    The Opus#3 fits nicely in ones palm.

    Features
    I didn`t try out all the various features that the Opus#3 has to offer due t my stubborn luddite old school backwards attitude and way of life. Streaming?, meh more like screaming.

    I had no trouble connecting the Opus#3 to the ifi Nano iOne which is connected to my simple home mini system of Onkyo CR-N765 with D-112EXT speakers. I found connectivity better without the leather case and was able to walk around the room without loss of connectivity.
    Wifi I mainly used for updating the firmware without any hitches.
    The USB DAC certainly improved the audio output of my Macbook pro. the set up was easy and quality of audio excellent.

    [​IMG]

    Value
    The Opus#3 retails for US$899.
    This price fits in nicely between the two forerunner Opus daps.
    Opus#1 retailing at US$350 - US$599, and the Opus#2 Dap retailing at US$1,100 - US$1,599 (depending on current deals).

    Musicteck in the USA have some good deals on all the Opus daps
    https://shop.musicteck.com/collections/opus

    I reviewed the Opus#1 previously (and still use it) and have only spent brief listening sessions with the Opus#2 at audio shows.

    I have covered the similarities and differences in sound signature with the Opus#1 in the sound section.

    The value lies more in what extras do you want?
    Opus#3:
    A slightly more increase in resolution?
    Wifi?
    Streaming music?
    Apps?
    Bluetooth?
    USB DAC function?

    And:
    One Burr-Brown DAC (Opus#3) versus two Cirrus DACs in Opus#1.
    Opus#3 supports 9+1 (aac) audio codecs, Opus#1.
    Metal and plastic casing - Opus#3, versus plastic- Opus#1.
    One Micro SD card slot versus two slots on the Opus#1.

    It all depends on functions needed/wanted for each persons intended use as to the value in this case.

    Opus#3 Dap, Jomo6R and Double Helix Cable Pure OCC Silver Litz IEM cable

    Overall

    The Opus#3 is the third in the Opus series of Daps, the #3 fitting nicely in between the #1 and the #2.
    For those of you who may be confused at the numbering system:
    The first is Opus#1,
    The second is Opus#2,
    The third is Opus#3...
    Product names are Opus#1 (HA-501), Opus#2(HA-600), Opus#3(HA-530).

    I reviewed the Opus#1 earlier and the UI navigation screens are the same. Take the link for the UI photos http://headpie.blogspot.jp/2016/07/the-bit-opus1-dap-review-expatinjapan.html

    The Opus#3 delivers a clean, nearly neutral and with a dash of warmth sound.

    The UI is easy to use and responsive.
    Firmware updates are simple via wifi.
    I found the Bluetooth to be strong, wifi connectivity is easy and the USB DAC function excellent.

    The volume wheel has a generous 150 steps, and is firm enough and protected against sudden increases in volume by the leather case. The leather case can loosen the wheel a bit, but I was able to retighten it myself.

    Its quite close to its cheaper sibling the Opus#1 but does edge it out, especially in longer listening sessions or when using the balanced out.
    Much of the operating system is the same when comparing the specifications. But the devil is in the details and the proof of the pudding is in the tasting. Opus#3=Yum.

    I ended up preferring the easy sound of the Opus#3 at the end of each listening session, I would happily plug the balanced cable back into the Opus#3, then slowly change it back to the Opus#1.

    Although change from two Cirrus Dacs (Opus#1) to a single Burr brown the Opus#3 loses nothing but seems to gain in smoothness, clarity, detail, sound stage and resolution overall.

    I would have liked a bit more power under the hood - but I generally didn`t max much past 80-90 on the volume side of things. And I do like to listen louder than most. It was more than satisfactory.

    The Opus#1 is definitely no slouch and has earned a stellar reputation for its many virtues, the Opus#3 just edges it out in sound, and of course overall features.
    The different features are listed in the value section.

    The Opus#3 is a device that can meet the multi media needs of the majority of todays demanding audiophiles, who desire a variety of functions from their dap of choice.

    "Another great player from Audio Opus"
    Pros - Balanced, transparent sound, great build quality, easy to use
    Cons - Firmware still has a couple of bugs
    Firstly I would like to thank Audio Opus for selecting me to review their latest player; I always try to write honest reviews. This player has had well over 50hrs of burn-in and has been my daily player for a while before reviewing, it has been tested with multiple headphones at home and at work.

    You can purchase it here from MusicTeck

    [​IMG]

    Tech Specs:
    MSRP: $899

    [​IMG]

    Packaging, Build Quality and Accessories:

    The Opus #3 comes in a similar box to its siblings, but in dark grey this time. The outer grey sleeve has the model number on the front, and tech specs on the back, once this is removed you are greeted by a blue box made of hard cardboard. Lift the top cover off and you are greeted by the Opus #3 held tightly in a velvet intray, underneath you will find the included accessories. The packaging has a very premium feel to it, and also serves its purpose of protecting the player during shipping. My leather case came in a separate small grey box.

    [​IMG]

    The Opus #3 is well built like the rest of their players; it has an aluminium main body, which is CNC milled and expertly finished, and a plastic backplate. Now I have seen people say the plastic makes it feel cheap, but here is my opinion, the plastic used is very good quality, the texture is great and also Bluetooth connectivity is very good, where an all metal chassis could affect this. All the sockets and ports are tight with no play in them, however the volume wheel does have some play in it. It does not affect functionality, but it is something I have always disliked in the A&K players (The Opus #2 wheel has very little play).

    Accessories included are a manual, USB cable, extra screen protector (one is factory fitted) and a very nice Dignis leather case. Everything you need to get going apart from a pair of headphones (which you have if buying this player).

    [​IMG]

    Usability and Bugs:

    First off the Opus #3 has the same UI as the other players in their range, it is a stripped back version of Android made for music playback. The main difference is the Opus #3 now supports streaming, but with limited 3rd party support. The UI of the main playback app is perfect; it has playlist support and is very intuitive and easy to use. You get the usual EQ settings, multiple gain settings, settings to change the DSP Processing (Auto, 16 or 32bit), balance settings and gapless on or off.

    You can toggle Line-out to use with external amps, this is not a true line out and the gain settings affect the gain on the line-out, but at middle gain it is set at 2.1vrms, and the quality of the amp stage is excellent so the line-out quality is perfectly acceptable. The 3.5mm jack can also be used as an optical output. You get aprox 8-10hrs playback out of this player, which to me is not an issue.

    This player has a touch screen which is good quality for a music player, with good viewing angles, and also has a couple of hardware buttons on the side for skipping tracks, and playing/pausing music, it can also be used as an external DAC/Amp via USB.

    [​IMG]

    Now to some issues:

    Firstly to install apps, you have to sideload them and install from the APK, which is awkward and brings another problem (To install, go to settings > streaming, then you click the little plus at the top, select the app you want o install, then install. You must press close after installing, and not open the app straight away).

    I have found that because apps don’t automatically close when you go out of them back to the regular player, the player gets very hot due to processes running in the background.

    To solve this you have to long press the app, and force close it, so not great.

    The only other bug I have come across is that using a 3rd party app, Bluetooth output stopped. Again these are issues that will hopefully be fixed in firmware updates. And when using as a pure player, I have had no issues.

    [​IMG]

    Sound:

    My opinions here are in comparison to the Opus #2 which is my reference point.

    The Opus #3 sounds a little colder in comparison to the #2, it sounds a little leaner but has the perception of being more detailed upon first listen. I wouldn’t say it is harsh, or bright just very neutral, towards maybe a little cold/analytical. This works wonders with most headphones, and brings out a little added sparkle in some more boring headphones, yet it still somehow works well with slightly brighter headphones. I would have thought it would become piercing, but again these are not night and day differences.

    The differences are small, but still there, the highs are very controlled and detailed without any harshness. This means that even though it has a tiny bit more presence up top compared to the #2, it is not a fatiguing listen.

    It’s always hard comparing 2 players that are so similar, but they are both fantastic pieces of kit, the #2 still edges it out with overall refinement and effortless sound, but the #3 in some ways is more exciting and more likely to reveal unheard nuances upon first listen.

    The Opus #3 has better attack and a drier sound, the Opus #2 is overall slightly more organic sounding.

    [​IMG]

    Conclusion: Audio Opus have done it yet again, a very nice player at a very good price compared to some of the competition. It offers a very engaging sound that is balanced, detailed and works wonders with nearly all portable headphones, and some harder to drive ones too. It has plenty of features and with firmware being updated regularly the bugs will be fixed.

    Sound Perfection Rating: 8.5/10 (Superb player at a good price, firmware needs a little work)
