EDIT2: I upgraded the X-FI card that I'm using as an optical S/PDIF source to a PCIE SB0880 . I'm guessing that this his one seems to have a more stable internal clock source.EDIT: I have added results through optical S/PDIF inputI have only tested in USB mode so far and found no specific issues other than its performance, in my setup at least, being strongly dependent on how it is connected.IMPORTANT note : I used RightMark Audio Analyzer (RMAA) and a MOTU M2 to record and measure the DS100's line-out performance, so the values shown are limited by the MOTU M2's line-in performance and ARE NOT directly comparable to other RMAA tests except possibly if the recording device used was also a MOTU M2.- Volume was set to max on the DS100 and its line-out was used.- Volume was set to max on the Apple A2049 and its headphone out was used.- Gain on the MOTU M2 was adjusted for level to be at -3.1dB for the DS100 tests- Gain on the MOTU M2 was adjusted for level to be at -3.1dB for the Apple A2049 dongle tests- The Apple A2049 needed 6dB more gain than the DS100 for level to be matched on the MOTU M2- The manufacturer provided driver was used through ASIO for the DS100- The default Windows 10 UAC audio driver was used through ASIO4ALL for the Apple A2049- The first column in the first image shows DS100 results through a Plugable USB2-HUB-AG7 USB 2.0 powered hub- The second column in the first image shows DS100 results through a Plugable USB2-HUB-AG7 USB 2.0 without power external power connected- The third column in the first image shows DS100 results directly connected to a motherboard USB 3.1 port- The first column in the second image shows A2049 results through a Plugable USB2-HUB-AG7 USB 2.0 powered hub- The second column in the second image shows A2049 results through a Plugable USB2-HUB-AG7 USB 2.0 without power external power connected- The third column in the second image shows A2049 results directly connected to a motherboard USB 3.1 port- the MOTU M2's performance is unaffected by the USB or not of a USB hub (powered or unpowered)- I also tried some unpowered USB 3.0 hub which, AFAICR, were actually worse than a direct connection for the A2049). Again, the MOTU M2's performance was unaffected by these.- The computer's PSU is a Corsair RM750x- The motherboard is a Gigabyte B550 Gaming X V2 on which I used the Q-Flash Plus Port (I summarily tested other ports before and saw no notable differences)Conclusion : IMHO, the SMSL DS100 is worth it to me. A decent DAC with powerful output (and a headphone amp), S/PDIF input, physical volume control and good specs, at this price is very nice.

同軸、光、USBを主に各均一に聴いてます。現在とても満足してきます。USB入力機器がもっともチープな機器のためか、2万円クラスのDACから本機とした際の向上は素晴らしいものでした。クロックの効果と推定しています。ただしUSB入力は、当初かなりキツイ音でした。前述のような3入力使用を合計で　一日6時間✖️14日　ほどで、安定しました。操作面のトラブルは、私の購入品は、USB使用のあと、一度電源OFFとしないと、他入力は認識しているが音がでない症状があります。対応わかれば問題ないので、このまま愛用します。

Je voudrai un mode d'emploie en Français et surtout en savoir plus sur l'alimentation électrique de l'appareille

It is a pretty good DAC. Simple to set up, functions well, good sound quality, and overall a very pleasant piece of equipment.One thing to note (definitely on me and not on the company at all), you would need to buy an adapter as well to use it with 3.5mm headphones/IEMs. Kind of wish they threw one in the box so it is compatible with some more standards.I only had one pair to test out the 1/4in jack, and it sounds good, but it is a pair that I don't intend to use with the DAC. Got an adapter so I can plug in my IEMs and got to use it to it's full capabilities after setting it up. Absolutely solid for someone who wanted a simple setup for simply good sound in a much more simple spot on my desk and closer to my head. All through one cable from my PC.Highly recommended for those who want their DAC placement to be a lot more flexible and even be some stylish desk candy to look at. The good sound quality is also a decent bonus on top as well.

Sorprendente! Appena arrivato questo mini amplificatore mi ha sorpreso per dimensioni, resa audio e versatilità delle connessioni. In pratica lavora con le HD 650 (300 ohm) con le HD 660S (150 ohm) e KLH (32 ohm). Le rese audio sono chiaramente diverse a seconda della personalità della singola cuffia. Mentre scrivo sono con le HD 650 (acquistate 18 anni fa!) connesse in bilanciato, bene senza burning, suonano alla grande. In confronto con amplificatori dal costo dieci volte superiore ci sono notevoli differenze, ma la Portabilità il Prezzo e la Versatilità ne fanno un ottimo acquisto per chi si sposta con il PC. Unica osservazione è la modulabilità del volume che presenta una progressione non troppo lineare e una certa latenza (ritardo nella risposta); forse un mini telecomando anche solo per il volume migliorerebbe un prodotto di qualità/ prezzo già notevole.
