SMSL DO100 PRO HiFi Balanced DAC with 2X ES9039Q2M & XMOS XU316, 768kHz/DSD512 USB Audio MQA Decoder Preamp, Bluetooth 5.1/Opt/Coax/HDMI ARC Input, RCA/XLR Digital-Analog Converter for PS5/Amp

I did a lot of research before I bought this and came to the conclusion that this DAC has amazing features for the price and is meant to sound brilliant so I took the plunge. Totally satisfied. I bought it especially for the LDAC bluetooth (HDMI ARC is a massive plus though), and I'm just amazed and delighted how good it sounds. I'm playing lossless Spotify which is hi resolution audio, via LDAC, with a NAD amp and Mordaunt Short floorstanders. The resolution is just so good. It's precise, punchy, full, there's space between everything. Basically it doesn't sound anything like the bluetooth of old. Sounds like a CD, or better. I haven't even tried out the HDMI ARC yet I'll edit this later. Great purchase though. Really impressive piece of kit.

Why did you choose this product over others?: Previous positive experience with SMSL products. I have a D6s DAC. This is essentially the same excepthat it has an additional HDMI input port for TV sound. Value for money: The price was reduced to £167 from the usual £209-£219 price range; I pounced on it!!! Sound quality: Its A-D conversion is good enough for all but the most forensic of audiophiles. It's clear and noise-free to my hearing. I use it with QAcoustic M20 active speakers and it plays LDAC over Bluetooth from my phone (OnePlus13) or music player (TempoTech V6) for good quality wireless audio. I read an online review that said the D6s was all most people would need as a DAC. I agree with that and as the DO100 Pro is an Aoshida spec'd D6s with an HDMI addition and wave style display at the front; that review still applies, from my experience. I do prefer the D6s styling but if you want a DAC to handle your TV's HDMI audio, this will handle it along with other types of input. The styling of the front panel isn't bad but I just prefer the look of the D6s. Just buy one or the other of these two DACs. I haven't regretted either. The value to performance ratio can't be beaten in my experience. As with all SMSL products, the DO100 Pro

Good sound quality for the price but turning up the volume with remote doesn't work unless you are directly in front of it and switching source can be annoying.

The USB socket fell out of my SMSL Sanskrit MKII, so had to use a very basic DAC for a few weeks. The SMSL D0100 Pro arrived day after ordering, fired it up with one of my favourite CD's The Beautiful South Solid Bronze Special Edition, a meticulously remastered CD. Am using an old Cambridge D500 SE as a transport and it sounded amazingly clean over my Sennheiser HD650 headphones and MF V90 balanced headphone amp.. Switching to my 2 Musical Fidelity P180 power amps, 3B Pre, Tannoy DC2000 speakers and sub the sound was powerful and refined, silent parts are just that. Only downside I have found is the DAC has left me feeling my headphones needed upgrading, another £500 spent this morning. High praise indeed for such a well priced and well performing DAC.

Very good sound

Unit display and functionality seems ok but there is no sound output through the RCA connection. Tried both usb and blue tooth, no joy. Returning for refund.

Splendid device, decent sound quality & easy to use/setup.

high price performance unit. remote is not very sensitive, you should face the unit to control otherwise it is unresponsive.

下らん長いレビューと、 セーフティーを張っときます..... σ( ⸝⸝⸝-∀-) 始めに、 製造国特有の不具合に 出くわす事は置いといての話です..... (ﾉ≧ڡ≦) ˉ̞̭ ˄̻ ̊ 私はREVEAL402にXLR接続、 テレビとはARC接続で楽しんでいます。 ARCのトラブルも有る様ですが、 今のところ大丈夫みたいです..... ただ時折(かなり稀)、 音がTVスピーカーに戻る事もありますが、 再起動で直るので問題無しです。 素性の良いアクティブスピーカーには、 うってつけなのではないでしょうか！ 今まで3.5のステレオプラグで 鳴らしてましたが、 (左右は3.5ステレオケーブルでのリンク) 音のクリアさに驚きです！ BS4Kで音物がある時に聴くと、 見たくも無い番組に、 没入してしまう程です！ ('▽`) '`,、'`,、 気を付けて欲しいのは、 電源プラグが 3極のアース付きと言う事ですね〜..... こだわる方はアースをきっちり、 こだわらない方は3極受けのタップ (アースには多分繋がってない)で、 問題無いと思います。 因みに私は、 3極受けのタップでも ノイズ等は乗ってません。 漏電遮断器があるお宅なら、 感電も心配は無いかと〜..... (ご自身の判断で.....) こんな安価なシステム構築で、 昭和の時代の高級システムを凌駕する 音が出せるのは驚きです！ アクティブスピーカーも合わせて、 音の出せるトータルで ¥60000以下なんて、 昭和の時代じゃ プリメインアンプの入門機に 手が届くか届かないかの価格..... もちろんアクティブスピーカーのみで、 音は出せるのですが、 特にTVの3.5ステレオミニジャックからの 出力に頼るよりは、断然良いですよ！ 画像に対しての音声のシンクロずれは、 TV側の調整なので、 気を付けて下さい！(●︎>Д<)ﾉ

Ich bin mit dem Produkt sehr zufrieden. Die Klangqualität ist sehr gut – angenehm, eher neutral und ausreichend detailliert. Auch die Verarbeitung der Tasten und das haptische Gefühl sind sehr hochwertig. Die Anschlussmöglichkeiten sind ebenfalls interessant und vielseitig. Ein kleiner Nachteil: Wenn ich das Gerät über den ARC-Anschluss mit dem Fernseher verbinde, ist der Ton zwar hervorragend, aber der automatische Wechsel zwischen dem optischen Eingang und ARC funktioniert nicht immer zuverlässig. Wenn mein Streamer am optischen Eingang angeschlossen ist, muss ich das Gerät manchmal aus- und wieder einschalten und manuell auf den ARC-Ausgang umstellen, damit der Fernsehton korrekt wiedergegeben wird.

Recently I’ve gotten into resurrecting some vintage HiFi systems (starting with my dad’s Revox). The issue is that they obviously don’t have an internal Digital to Analog Converter to run streaming services. I’ve been using S.M.S.L. AO300 by Aoshida for the last few weeks as a general compact HiFi for streaming and to power some external speakers for the TV. I was so impressed by this little powerhouse that I wanted to try one of their DAC units. As it happened, Aoshida just released the DO100Pro, an upgrade from their previous high resolution DAC. I was lucky enough to buy one of the first units, so figured I’d give a quick rundown. As with the previous S.M.S.L. AO300, it comes very well packaged with a manual, computer style power cord, USB A to C adapter cable, Bluetooth antenna and a nice little compact remote (you do need to add batteries). The case is all metal, with a CNC front fascia and formed metal main section. It has the updated fascia style with the wave design over a plain box design of the previous DO100. There is a good sized display screen with large font and next to it a concave selector knob/dial for volume and menu selection. On the I/O back panel there is a pair of balanced XLR and a set of single ended RCA outputs. As far as inputs, there is a wide array: Optical, Coaxial, USB-C 2.0 and 1.1(for game consoles), Bluetooth 5.1, and HDMI ARC, which is new on the Pro. Internally there are upgraded components over the previous model. The new dual ESS DAC chips have better dynamic range and ultra-low distortion, and there is a new 3rd generation controller chip with two additional Op-Amp chips, for a total of 6. There is also decoding for MQA in the Pro model. I don’t dabble in that, so can’t say too much about it. This is a DAC only, so it does need an external power amp. I used it directly on powered desktop speakers, and a few different passive speakers via vintage and semi-vintage amplifiers. I do not have any XLR gear, so I did not have a chance to test that. Sound wise this DAC is exactly what I’d hoped for. Just as with the AO300, there is an extremely low noise floor (non-existent basically). The tiniest of details can be clearly heard on decent speakers. Obviously speakers make a big difference in how good things sound, so the better the speaker, the better the sound quality. That is probably my only gripe with this and the newer high resolution audio equipment - you really notice the difference between good and bad recordings. No matter which input I used, all worked flawlessly. The Bluetooth 5.1 connected with my phones immediately, and stayed connected throughout my listening area, which is pretty much the whole house. I use an older phone as my streaming device hooked up via USB-C. This allows me to bypass the phone’s internal DAC and lets the DO100Pro do its thing. Usually I use this while sitting in the listening sweet spot running a playlist and use the remote for volume. My current phone is connected via Bluetooth, so I can change music if I’m walking around. The interface is streamlined and simple to use. Pressing the dial center enters the program menu, starting with input. It cycles through USB, Bluetooth, Coax, and HDMI ARC. Another press puts it into the PCM filter selection, of with there are 7 levels. Next are the 9 DPLL settings, which is for clock jitter. The default of 1 for both of these worked just fine for me. Lastly is the brightness control of the screen. For me, the DO100Pro is a homerun for Aoshida. Though it’s an entry level model, it doesn’t compromise on sound quality, and that is the most important part of course. The higher models have more features such as sound modes, more complex screens, and internal headphone out amps, but those all come with a price increase. If you’re looking for a quality high resolution DAC that doesn’t require a crash course on settings or break the bank, the DO100Pro should be on the short list.

Le DAC SMSL DO100 Pro tient toutes ses promesses: 1- Très belle finition, connectique très complète, bien documenté et facule d'installation 2- Son précis et neutre, avec de la profondeur, un bon aigu et un grave bien tendu 3- Possibilité de plus ou moins "colorer" le son à son goût via des configurations pré-determinées. Moi qui suis habitué à des systèmes HIFI de taille plus imposante et des prix supérieurs, je suis sous le charme de ce DAC qui présente de très belles performances. Je recommande.

I have owned many DACs and AMPs over the years, but recently purchased the DO100 Pro to use with my SMSL A300 in a new bookshelf speaker setup. I am absolutely blown away by the sound at this price point. The ESS chips are revealing and detailed without sounding overly bright or harsh to my ears. The XMOS USB chip works flawlessly. I did have to install a driver (when using in the USB 2 mode) on my PC, but this was no trouble at all. I feel like the same product would have cost 2 or 3 thousand dollars from the likes of Audiolab, Naim, etc... whose products I all enjoy. But this costs $250 CAD and fits comfortably next to my PC on my desk. Unreal. The remote is not the best, but with a DAC you're probably going to set it and forget it, so I consider this to be a non-issue. Build quality is great. No cons that I can think of. Paired with the A300 (which has a high pass filter and sub out), SMSL's latest offerings make this kind of setup possible without breaking the bank and with exceptional sound to boot. The features, performance, and price speak for themselves. It's worth noting I ordered the AO300 thinking it would be better to have everything in one unit, but the DO100 Pro sounds a lot better to my ears paired with the amp-only A300. This way you also don't lose the ability to high pass your mains and can get bigger sound, which I enjoy.
