Well, I would recommend that you consider replacing your preamp too, as Zd542 also noticed, this is a weak link. A Krell KAV-300i or Plinius 9100 integrated amp would be a nice upgrade over your Adcom seperates.
If stuck on your Adcom preamp, and only looking for an amp, I'd recommend looking for an Classe, Aragon or Forte amp.
