I use the amp in conjunction with the AS-301 Dynavox satellite speakers and am very satisfied.
Sonically the middle listen to something tinny, but I did write to the LS, as this was also criticized by users.
On the other boxes I have not tested it.
The max. Volume is enough for my application fully komen, it is operated by me using Ni-MH batteries.
I can not say anything more precise, because I had him only about 4-5 hours in operation over the period.
