NAD C320BEE Rotel RA-01 Cambridge 640A

The C320BEE is perhaps the best value I've ever heard. I currently have one in my system and have no plans to replace it anytime soon. It does have both preouts and amp inputs, so you could conceivably get more life out of it than the Cambridge.

now ehat you think is better amp for acoustic energy evo one's? c320bee or ra-01?

the nad is a steal.i use with gma europas and nad541i and it has probable 85% of my other sys. which costs 10 times more.if i knew what i know now,i would have saved a lot of money.you dont have to spend big to have good sound.
