Review: Brilliant Sound, Superb Value - Bought this is on review recommendations. Just had an 1990s DAT player refurbished, brought back from the dead after it had spent thirty years in the garage, now it plays perfectly but it had a somewhat compressed sound. This DAC has one of the very latest/best chip sets usually found in units at ten times the price, the DAC in the DAT is thirty years old so could benefit from the latest tech to give it a boost. Some people think all DACs are the same but they are clearly not, a listening test shows this very clearly, just as all headphones don’t sound alike. I have six DACs, some are good, some are not so good and it does not always relate to cost. A have a Fosi which is ok as a headphone DAC and pre amp which is ok, warm sounding but lacking clarity, a Beyerdynamic slightly better but not enough for the additional cost, a Chord Mojo which is very good used between an ipad and twin rca cables to an amp, a Prozor for 5.1 sound from a modern tv to ancient analogue cinema amp which was very cheap but sounds great and now this which sounds brilliant, better than the Chord but at about a fifth of the price. A good DAC puts air and soundstage into the music, separates the instruments and gives clarity to bass and treble. This one has opened up the sound of this DAT player, giving a clearer sound, very pleased with the result for such a low cost item. Also as the DAT is optical cable and the CD player, also from the 90s, is coaxial digital, this unit can take both items and you can switch between them using the button on the front.
Review: Progress - Like most people, my interest in sound devices and recordings is simply about getting as close as possible to the sound of a great performance of the music to which I listen. Bach, Bacharach, Basie, whatever. And this super little sound device constitutes very siginificant progress in that quest. Connected by USB to my PC it takes PCM and DSD files, converts them and sends an analogue signal to my desktop amp (Douk Audio T6). I listen to the output on Sony MDR 1 headphones. Like everyone with good new equipment I hear things differently and more clearly on recordings I have loved for years. Dynamics, attack and decay of notes, balance within ensembles, tonal nuance and so on. The S.M.S.L. SU-1 makes it all possible. Set up and operation are simplicity itself and the Roon music library/player connected immediately. (The only advisory I offer is to ensure you download and install the relevant driver to facilitate ASIO again easily done from the SMSL website) All this for a derisory price compared to regular hifi equipment. The only regret I have is that I now won't be trying out anything else for some time to come.

## 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.
