Need more info on the Electron Kinetics Eagle-7A

Hi all!
First let me explain that I am currently using a Perreaux 3150B amp in my system to power the woofer columns in my RS 1-B speaker system. I previously had a Perreaux 2150B amp and before that a Bryston 4B. With the help of you all and especially Sean (thanks Sean) I decided to get the Perreaux 3150B. I bought it used. When I hooked it up I got a hum (not audible when music is playing) through the right column. I was also, however, getting a funny noise (sounding like sneakers of a gym floor?)every once in a while and when I powered it up. I brought it in to AnalogiQue for repair but they found nothing wrong. By the way...with my Perreaux 2150B back in place I get dead silence. So I'm thinking the amp most go (maybe).

Someone has an Eagle 7-A amp for sale....I tried looking up reviews but could not. Anyone here have experience with it.

I would also welcome comments on the following amps I am considering:
Bryston 7B
Threshold Statis 500
Krell KRS 250
Rotel 1090

Thanks again all for your help and support!!!

It's been a long time since I owned the RS-1Bs, but I remember the crossover having a servo control function. This may be creating a feedback problem with the Perreaux. Have you tried floating the A/C ground on the Perreaux?

The Eagle 7A is a great bass amp, but who's going to fix it
if it breaks? Nothing beats a Bryston for performance and reliability.

Another amp to check out is the CarverPro digital ZR1600. 300 watt/channels for $1k.

Finally, those tall woofer columns in RS 1-Bs can be improved with some Blackhole 5 applied to the inside long
walls.

Sean- I don't understand why you want to put down an amp you haven't heard. Yes, it didn't test well, but even Mr.Cheney feels it sounds really good. For those who are interested, here's part of his comments(the rest can be found on Audiocircle.com):

Brian Cheney-subject: ZR 1600 comparitive listening tests:

"I'm not going to keep you in suspense: this amplifier has a sensational sound and is all the web buzz cracks it up to be, and more."

Carver Professional is a division of Phoenix Gold International, they have never claimed to have anything do with Bob Carver. They bought the name just like Superscope did when they bought the Marantz name in 1964, and just like Philips did in 1980, when Superscope sold them its shares of Marantz Japan.

Rick- when I owned the RS-1 B, I had a ARC D79B on the panels and Electron Kinetic Eagle 7A on the bass towers and there was no hum.

After reading your post again, I suggest that with the power off, you gently push on the center each woofer in the right tower and see if you hear any scrapping noise. You may have a woofer(s) with the voice coil out of aliment, which could be making the "sneakers of a gym floor" noise when the servo control powers up. Aloha, Kana.

Rick- one final thought- if you have a multimeter, check the DC offset in the right channel of the 3150, If it's off(should be as close to 0 vdc as possible) or not stable(compare it to the left channel), it could be interacting with servo crossover to cause the your problem.

Sean- I haven't heard the Perreaux 2150B/3150, I'm sure
they are excellent amps.
