There were big problems with the item delivery, but I'd rather blame the post service for them and not the seller. The seller was very helpful, and the item works pretty well.
Pretty great sound, especially for the money. Natural sounding, no harshness in the vocal region and treble at all. Very powerful, drove my speakers without a sweat, even at high SPL levels. Noise performance is exceptional, I can turn my preamp (it has very high gain mind you) knob at max volume and can barely hear any hiss out of the tweeters of my speakers. Minor gripe is that the soundstage is rather narrow, even with R2R DACs and tube preamps. Can't ask more from a $100 amp I guess.
