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.

Performance is TOP quality both in USB and Optical I have not tried the coaxial output... I bought this for home use to my Harmon Kardon amp it is amazing quality don`t buy the over priced DAC`s this will make the difference you are looking for. This is pure and simple less chance of noise from LCD screens and other knobs or buttons. When using optical you need to power the DAC from the USB C port. Not sure about Coaxial port. USB C port works in Windows 11 just plug into your computer and it gets power and plays your audio all from that port. The web site stating it works with android, they should state Tablets only as it will not work with cellphones unless you have external power supply using USB C Splitter, Dual USB C Headphone and Charger Adapter,2-in-1 The single end to the dac, Then you will need the Fosi Audio DS1 supplied USB C cable to connect the splitter to your cell I've tried other quality 6inch usbc cable but it will not connect to cellphone only works with shorter cable that came with fosi ds1 dac. I even tried a smaller adapter with no cable just USB C males ends and still it will not work only the Fosi Audio DS1 cable will work... Another warning is you have no volume control when using your cellphone so you need to have it playing through something with volume control.... I know this as I used a RCA to AUX cable to use it with headphones so only full volume that way !!! I contacted SMSL customer support on Facebook requesting firmware to be updated but they are not helpful at all very ignorant. I just found the actual link for customer service on there web site and requested a firmware update.. Without the splitter and external power supply your cell will state what is below. The SMSL web site states it works with android but when I plug the USB C from my Galaxy A52 without external power supply the screen states very clearly quote : Android system High Power USB device connected Cannot access to this device. Connected device needs external power supply. I also bought the Fosi Audio DS1 USB-C DAC for my cellphone it is also very high quality don`t waste your money on more expensive portable DAC`s both DAC`s will impress.
