Review: 初めてDACというものをアンプに付けて使った。CDプレーヤーと中華アンプの間に挟むだけ。 DACと中華アンプを合わせても、DVDのケースくらいの大きさだ。 かつての重厚長大なアンプとは大違い。 しかも値段が数千円から数万円だ。お財布にとてもやさしい。 早速、名機ダイヤトーンで視聴。 あら不思議！通常CDがSACD以上の音質で出て来るじゃない。しかも音が澄んでいる。迫力があり、音が美しい。 もうSACDは要らないな。早く買うんだった。 DACを付けるのが面倒なら、DAC内臓のアンプもあるよ。 我々庶民にもハイエンドオーディオ並みの音質で音楽が楽しめるようになった。 名機オールドダイヤトーンをよみがえさせたDACに大拍手！！！ ブランドにこだわらないなら、音楽を楽しむのにはこれで十二分です。
Review: 本体はタバコ2箱くらいの大きさ wiimproの外部DACで使用してますが、音質がとても良く気に入りました（値段も安価なので）

## Features

- USB is compatible with MQA: 1. Cleans up recordings, when converting analog audio to digital signals, time jitter occurs, causing transient signals to blur over time As a result, our ears can no longer tell where a certain signal is located By comparing recorded music and live performances, a single sound is created The performance of "playing" is not noticeable MQA eliminates this distortion and creates a true 3D sound field that is different from previous sounds
- 2. Enclosing sound: In MQA, after removing recording jitter, something called "musical jitter" is used Origami Mprocess, this clever device manages large resolution files easily and is compatible with all services and playback devices
- MQA CD Support: Compatible with CD player + MQA compatible DAC, the digital output (optical or coaxial) of the CD player can be supplied to the MQA compatible DAC It is a coder The MQA decoder can restore and play back the original high-resolution audio signal SMSL SU-1 is compatible with MQA CD
- AKM AK4493S: The SU-1 adopts the latest AKM DAC chip, AK4493S, achieving distortion of 0.00013% or less USB In: Compatible with Windows7/8/8.1/10/11(driver required), Mac 0S X10.6+, Linux (driverless), Android, i0s

## Questions & Answers

**Q: When I hook it up to play there is music for a second or two and then no music for a second or two. This repeats itself over and over again. Ideas?**
A: I do not have that problem with this device, HOWEVER, I do have that very same problem with another SMSL dac ( M500 MKII), and I have not been able to figure out why this happens. I do not use Windows, and I only play wav files with Linux based software, and Linux operating system. Make your own conclusions.

**Q: how come the output voltage is so low when I connect it to the optical on my TV?  I thought the output was suppose to be 2 Vrms.**
A: only tried whit coaxial in rca out

**Q: Without a separate power input, how much faster does the battery drain on the cell phone?**
A: It consumes very low energy. I don't use it via USB. I haven't tested it.

**Q: I'd like to listen to one of those new MQA-encoded CDs. Will the optical output of my legacy CD player pass the MQA-encoded signal to this SMSL?**
A: Yes, because the SMSL is reading, converting the signal and your legacy CD player is functioning as a transport only.

*by チ***ル on January 23, 2026*

ｐｃのアナログ出力から、ヘッドホン用のプリアンプ（オーディオテクニカ製品）経由で、スピーカー（アンプ内蔵wavio）へ、今まで接続してた。 プリアンプの代わりに、このＵＳＢ経由のＤＡＣにしたところ、非常に素直な音になったと思う。でも、JAZZとかには。向いてないも。 プラグ＆プレイで接続できますが、ドライバは、メーカーサイトで落とせるので、それを使ったほうが安定すると思います。 windowsのストアでいろいろ味付けできるソフトもありますが、使わないほうがいいかな？
