the best amp to run the bass of infinity RS-1b's

I have a pair of infinity rs 1b's and am running them with a pair of bryston 4b-st's. I have a nakamichi dragon 3 piece cd setup with a nakamichi CA7A pre-amp to the brystons. I have 2 pairs of mit MH-750 CVTerminator II cables to the speakers. I am looking at a pair of Bryston 7b's at 500/ch at 8ohms, 800/ch at 4ohms. Classe Ca-400 400/ch at 8ohms, 800/ch at 4ohms. Mcintosh mc2500 500/ch at 8ohms. Perreaux 5150b at 500/ch 8ohms. I like rock,jazz country and classical. All the amps are for sale in my area and I am wondering which would give me the best punch and sound for the type of music i listen to.

Thanks for the help

P.S. On a follow-up to my original post dated 10/25/03 my original 3150B WAS not working as properly as I expected. I tried to eleminate the hum but could not. However, I was fortunate to find another on (here as a matter of fact) that runs and is running beautifully. I keep an eye out for the 5150B however!!

Hi Darin....I have the same speakers you have! Listen to Sean...he has helped me out quite a bit! I also had Bryston 4B's but went with a Perreaux 2150B because it had a warmer sound that mated well with my set up.
The desire for a more powerful amp led me to the 3150B (Sean's suggestion) and I got it. Although I am in the mist of trying to slove a few problems (hum and funny noises), the amp is quite powerful but still retains the warmth and overall synergy with my tube amps on top.

I will watch this thread closly. Good luck

Hi Brian, I have also heard some folks doing away with the Infinity crossover. It gives me a little scare to do that although I get tempted now and then. I believe if you use another crossover (bryston, Dahlquist, Merchant) it negates the servo control on the woofers. Some say it sounds better and some say it does not. The Krell amp that a friend of mine has on his woofer towers are the 150 mono's. He retains the infinity crossover.
As to an update on my newer Perreaux 3150B...now that I have had it for a few months....it is wonderful......plenty of power and control!!
