Noise floor is nice and low. UI isn't the sexiest, I'd badly like a frontpanel power switch, and it'd be good to have two WC inputs considering there's bidirectional SRC and also to be able to turn off the frontpanel lights, but these are very small gripes. Unit is solidly built and compact. It gets warm but not hot and uses a proper IEC not a wall-wart. Very nearly matches its RME competition at a much lower price, and from where I stand the quality is on a par too. Recommended.
