Sound.

Crappy connectors

150W per channel monoblocks. It's unbelievable what a beautiful sound those small boxes can produce ! The best sounding amp in the pricerange.
The only annoying thing is crappy binding posts.
Shame on you, AVI ! This amp deserves better connectors. Bi-wiring is painful.
I rate it 5 for the sound, 4 for the building.
