Advice needed for an USB DAC

[romain]

Have a look at Topping and S.M.S.L USB devices. They seem to be pretty popular and are generally available on Amazon. Best to buy from a source that offers unconditional return in case you don't like the product.

I just got an SMSL SU-1 currently about $90.  According to ASR measurements it's equal to many DACs in the $500 category.  It supports MQA but you're under no obligation to play any music that supports it.    It has the more or less standard USB, Toslink, and SPDIF inputs and RCA out.  It's tiny, not much bigger than a Rasperry Pi.  My subjective impression, FWIW, is that it's not there.  It just passes the signal to an amplifier as a DAC should.

Thanks for the suggestion.
