The SU-8s is the refreshingly straightforward new DAC from SMSL. Who’s it for? The research-weary. The comparison-chart-chafed. The do-I-look-like-I-know-what-a-PCM-filter-is. It’s a DAC that remembers what a DAC should do: decode the highest song files on the planet, and do it well (really, really well). And that’s it. Oh, and it’s got a nice remote.
