Oh geez, another thing I want to buy.
I like these gizmos Kingwa comes up with. All of the units I've bought- Compass, FUN, and now the NFB11 - work really well as stand-alone DACs, pretty good as preamps, and better-than-average as headphone amps- and they don't cost much. The build quality is really nice. They look OK, kind of utilitarian; now if Kingwa could get someone with industrial design skills on board to give his products very sleek or subtle cosmetics- that would be great.
