FWIW, a looong time ago, I owned a couple of different Carver amps. The little 400 watt cube and the really cool looking 500 watt amp with the big analog meters. I don't remember the model numbers. Anyway, I bought a Rotel 980 bx for $600, the Rotel was better top to bottom, in every way, shape and form.
I have not heard any of the Sunfire amps.
