Audio-gd has a large following on the headphone-related audio forum Head-fi, both for its headphone amps and its DACs. Supposedly Audio-gd provides very good customer support, even though they are based in Asia (Hong Kong?). The only downside has been that their headphone amps tend to run very hot and some feel they have inadequate heat sinks.
I have read nothing about their preamps or power amps, either on this forum or anywhere else, except for your comment. That means resale value will suffer. My experience is that this is the case with all China-branded equipment (Eastsound, for example). It seems inexpensive relative to other new components but you can pretty much forget about ever selling it used.
