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

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 there,

Oke I didn't listen to this amp myzelf(jet) but I hear great things about this amp.

The Crown Audio K2 it's 500w 8 ohm and goes all the way down

I'ts price is about 1300/1400 dollars on internet and damping factor is < 3000 Stereo Times had a great review on this amp. I'm gonna use it on the low of my IRS Beta's

It has a better slam than the Krell kma 200 ect...
This of a friend of mine that sold the Krell after listening to the K2

let me know what you gonna do.

I purchased a Pereaux 5150b, and suposibly in shipping it was damaged. I hooked every thing up and just got a buzz niose from the speakers. If I turn the pre-amp up to just about full volume the buzz would stay the same but I could just hear the music, maybe only a couple of watts of out put. So I have taken it to a shop and hope they can find the problem. I will let you guys know how things turn out.
A friend runs his RS1b's with a pair of older Krell monoblocks on the bass towers, sorry I don't remember the model, and an ARC D250 on the panels. He dispensed with the trouble prone Infinity crossover and uses a Dahlquist active crossover.

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!!
