If you are going to use it for 5 channel, the Carver 705x THX is an excellent amp was $1300 retail and can be had for about $600 used. If you want any better go to the Rotel 1095, B&K 7250, or Parasound 2205. These are all 5 channel amps and a slight improvement over the 705.
Best amp match for Paradigm Studio 100s
Thinking of the following: Anthem MCA-2 - good reviews, inexpensive Bryston 4B-ST - good reviews, a lot more expensive than the Anthem, Is there that much of a difference between these two?? Any other suggestions are welcome. Not too concerned about the cost, but don't want to spend if I don't have to. Thanks
