Anthem A series. They have a very fast and smooth personality. Destroyed the Adcom that I had. It is Much more pleasing to listen to for long periods. I also had an NAD218 that was fantastic but limited due to being a 2 channel amp. I wanted to match my front sound stage. The Anthem Gives me most of what the 218 had. A little better on top but a little shyer bass.
I have also heard Parasond, Rotel,and B&K amps in this price range. I would prefer the Anthem.
