Need help. I just purchased the Anthem avm20 v2, and my speakers are all Klipsch Ref 7 series, fronts, center, and two set for back and surround sounds. My dilemma is that I don't know which 7 channel amp will match well with my system. I will be using it 50/50 HT/Music. Some Amps that I had in mind, not in any particular order are: 1)new B&K Ref 200.7, 2)new Sherbourn 7/2100, 3)Adcom 7700, 4)Aragon 2007 amp, 5)Krell Showcase7 6)Anthem pva7 7)or any other recommendations of other Amps. Thanks to all.
