I'd like to ask for some opinions on how Adcom rates in the world of amplifiers? ...and in particular, as compared to Rotels. I'm considering either the Adcom GFA-5006 or Rotel RMB-1066 ... frankly, I'm leaning towards the former, because of a store credit situation. But if the Rotel's really in a different class, I'd have to rethink. Thanks!
