Review: Dac seems to built well. It feels like a quality item in hand. The recent reviews on desertcart are spectacular. For me it didn’t work. No sound. When I tried to download the drivers for my device listed on the SMSL page they would not install? There is no customer service no. Thank goodness for desertcarts easy return policy. As a footnote when adding a third party dac into an existing audio environment a lot can go wrong. From wiring to software conflicts and so forth. When searching online for other buyers with similar problems I found very few posts as SMSLs products seem to work pretty well out of the box.
Review: Trochę nie wierzyłem, że tak tanie urządzenie może coś poprawić. U mnie jakość dźwięku z podstawowego streamera (TagaHarmony) zdecydowanie się poprawiła - dzięki głębszym basom i większej selektywności.

## 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.

### ⭐⭐⭐⭐⭐ Review
*by P***E on 31 May 2025*

Très bon. Bons timbres, très dynamique et clair. Bonne profondeur de scène sonore. Il a remplacé un Topping E30 et est nettement meilleur. L'avantage est qu'il n'y a pas de filtres, ni de suréchantillonnage avec une lecture CD. Comme on dit en anglais, "Less is More". Il a de bonnes basses, bien tenues, mais pas extra profondes. Il manque un peu de medium. J'ai essayé ensuite le D6s qui avait un son dur dans les aigues et artificiel sur mon installation. Donc, je garde le SU-1, qui est imbattable en rapport qualité prix. Il faut lui associer une bonne alimentation linéaire et de bons câbles pour en tirer le maximum. La puce AK produit des sons très naturels. Je n'ai pas du tout aimé le son de la puce ESS sur le D6s.
