I've tried out its immediate predecessor, the C520..as always, NAD's build quality at this price level isn't stunning (of course, NAD products are never top of their league in that respect), but it's a lively player with decent bass and a not-too-forward sound. If the C521's anything like the 520, I'd get it over almost any new CD player at that price point (yes, I know about the AMC CD8B); that said, I'd almost certainly go bargain-hunting for a used, higher spec'd player first.
