What's up RGA?

Probably not the space saver you need, ATI make No Feedback multichannel amps. If you go 3k series or up the sound quality is beyond it's range. They also require a 20v outlet which may or may not be an issue where you live.

Parasound will have a new higher power 5-channel amp soon but I doubt zero feedback.

My only audition of Wyred4Sound I thought they were neutral, not quite what you describe looking for, however, multichannel, Class D is worth exploring.

I still like the Marantz processors as a sweet spot, you get full featured as with mass market, yet better than mass market performance, IMO.

HT reviewers like Anthem but using a computer and software to set room EQ is a turn off to me, although it's said to be one of the best EQ's going.

Then you have your higher dollar less featured units like Bryston, with great sound, I should add.

I see Lexicon introduced some gear at CEDIA but I haven't had a chance to see what any of it is about.

ATI make No Feedback multichannel amps.

Which model(s) are you thinking of? Certainly not the AT6000 or Ncore based AT52XX series.

  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.

I figured my request would be difficult - I looked up the Bryston pre/processor but it doesn't have a bypass for 2 channel. Bryston amps don't sound particularly good with Audio Note speakers - high negative feedback is not a match.
ATI from what I read are all feedback amplifiers.
I have yet to like Class D but I will keep an open mind as I have not heard a lot of class D amplifiers so as they say - it just could be the implementations that I have heard have not been too my taste.
Thanks for trying - it seems like this could be difficult.

  "bypass for 2 channel"
  
  Yuuk! I doubt your going to like that.
