Review: Le stelle sono 5 ma potrebbero essere 6😉 Il DAC è molto ben costruito, piccolo ma "pesante" , tutto in metallo di buona qualità. Riguardo il suono: suona molto bene, per il prezzo poi suona in modo eccellente. Io utilizzo dac di vario tipo, anche apparecchi pro usati solo come convertitori, e questo piccoletto non sfigura affatto. Confrontato con il mio dac" di riferimento " ( uno che avevo assemblato anni fa, con alimentazione separata ,op- amp sostituibili, e, guarda caso con un vecchio chip AKM, perde solamente qualcosa nella gamma bassa, che è meno estesa e presente. Quindi in sintesi: se non volete spendere centinaia di euro ( parecchie) questo è sicuramente la scelta giusta. Sono rimasto abbastanza sorpreso, perché non credevo suonasse così bene
Review: Ok

## 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.

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。
