I bought an SMSL dac off ebay late 2108, abut £100, can't remember the name (M8?), it's tiny, silver. Partly I was swayed by audiosecincerevew saying how riubbsih the Shchiit Bifrost I'd had for years was (modified from Uber to Multibit), yet the SMSL exhibited a lot of annoying clicks through USB (which was supposed to the worst part of the implementaion in the Bifrost), especially with occasional 24-bit material (I don't pay more for that, e.g. Sunn0))) White 1 same price for 24/88.2). So annoying I bought a different dac. Also it wouldn't put out two channels through old interconnects that other sources had no troouble with.
I have never, ever heard such clicks before. And these thing according to ASR are supposed to be technically as good as it gets...
