All that I have heard sound good, though relative to cost...had a $200 SMSL that sounded good and had great feature set, but for me the Schiit Bifrost at $800 and the Denafrips Ares at $900 clearly sounded better...and I would have preferred to like the SMSL more than those...currently using a Schiit Modi+ ($129) on desktop and it's awesome for the price and all I need for that use..
Is there any such thing as a bad sounding DAC these days?
I think the problem of DAC for quality audio has been pretty much universally solved. Not to say all DACs are equal, they aren’t, but do any that really matter these days not sound “good”?
