Review: 安価な割にはちゃんといい音がします - MQA-CDをフルデコード出来るDACを探していて、この商品を購入しました。 中国メーカーの1万円程度の安価なDACにもかかわらず、ちゃんとしたいい音が出ています。 15年ぶりに購入したDACでしたが、満足しています。
Review: 優れたコストパフォーマンスです - 値段の割に作りもしっかりしてますし音質も数万円のCDプレーヤーに匹敵 するかと思います。MQAの再生はPCでは専用のドライバーが必要なようです 、CDプレーヤーからの光、同軸は問題なく再生できました。 音質は若干高域寄りで10年前のDACに比べ情報量と解像度は少し上がってい るように感じます。（個人的な意見ですが） DACの入門機としてお勧めできる製品です、耐久性は判りませんがこの値段 でしたらコストパフォーマンスで星5つです。

## 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.

### ⭐⭐⭐⭐⭐ 優れたコストパフォーマンスです

値段の割に作りもしっかりしてますし音質も数万円のCDプレーヤーに匹敵 するかと思います。MQAの再生はPCでは専用のドライバーが必要なようです 、CDプレーヤーからの光、同軸は問題なく再生できました。 音質は若干高域寄りで10年前のDACに比べ情報量と解像度は少し上がってい るように感じます。（個人的な意見ですが） DACの入門機としてお勧めできる製品です、耐久性は判りませんがこの値段 でしたらコストパフォーマンスで星5つです。

### ⭐⭐⭐⭐ 問題はUSB給電の質
*by A***ー on December 24, 2025*

既存のDAC-SQ5Jからの乗り換えです。 DAC自体に不満はなかったのですが、些か古くなり更新に至りました。 PC音源なのでそもそも繊細な音質は分かりませんが、電源がUSB給電なのでそこがかなり気になりました。 そこでFX社のUSBノイズフィルタを経由させると音色が全く違います。 特にキラキラした音質が滑らかになります。 元々のDACにはラインフィルタを挿入していたのでノイズが気にならなかったのですが、当たり前なんでしょうがスイッチング電源の平滑回路だけでは音質への影響は無視できないと改めて感じました。
