ATI make No Feedback multichannel amps.
Which model(s) are you thinking of? Certainly not the AT6000 or Ncore based AT52XX series.
Follow Ups:
I thought the 3000 series was zero feedback, I auditioned one and was told that by the dealer who brought it over. He may have assumed that from the Theta amps though.
The 6000 series says, "2. The design uses current feedback instead of the more common voltage feedback. The reason: current feedback amplifiers are faster with virtually unlimited slew rate and are better able to reproduce today's best music and film sound. "
Isn't the voltage feedback the type called negative or global?
I hve to go now but will do some more chcking.
feedback, regardless of how you source it .
A difference component derived from source and output are mixed back into the output signal.
I didn't find a reference saying the ATI had zero feedback so I stand corrected.
Most companies who boast zero or no feedback seem to be referring to "global" or "negative" feedback. It would seem if current feedback was a negative in any way it wouldn't be listed as a positive in the feature set of ATI 6000 series.
The Dreadnaught was definitely zero feedback. So is Ayre and I believe they do have a 5-channel but I'm not sure if it's a current model. Coda is zero feedback but if they have a MC amp 'm not aware of it. It's a shame I really think RGA would like Coda.
I wish I had more time with the 3000 series amp, it had a brute force about it like no other amp I've had in my system. Not offensive, just a bass authority that really pumped the drivers.
I just reread what I wrote and I would have to change speaker cables regardless. Main speakers would be connected to the 2a3. So I would have to take the cables of the monoblocks and connect them to the SS amp. That's better than at the speaker end though.I looked up the Ayre - they claim no feedback - and modular - It's on their website so perhaps it is still in current production. Probably pretty expensive though.
Second hand might be ok as well since typically it doesn't hold value very well at all.
