Well I am talking out of my ass here, because I've not heard this amp or the one I'm recommending. However, for this kind of monetary layout I'd have to give some consideration to some more established names. The NAD M2 comes to mind. It has garnered stellar reviews. Above your price ceiling, but possibly well worth the extra greenbacks.
