Feedback

Tony I certainly appreciate the listen and pick which switch position sounds best.... and Lord knows, my thinking on any subject evolves a bit with time but....

this is from the RM-9 owners manual, which includes RM note back to Stereophile in the review of the RM-9

” Not wanting to play “ God” over the situation, I chose to give the user a three position feedback switch so he could change the damping by a factor of approximately 4:1 “... he then mention gain, passive etc

in my system with what I consider to be a very neutral tweeter, I prefer the high gain / low feedback setting.... it sounds glorious...

And Roger’s ( RIP ) masterwork RM-9 has switched 3 levels of feedback which aids one in discerning the impact on sonics.

certainly there are amplifiers that sound good with no global feedback as well: Atmasphere, Ayre ( RIP Charlie), Vandersteen, et...

and of course we should credit Dr Matti Otala for his discovery of TIM and relationship to negative F/B. I still have an Audionics CC2 wildly inspired by Otala. It is a very musical SS amp designed and produced in the late 70’s

fatigue free listening.....

@cleo I sent you an email, need bit of help with bringing an RM-4 back to life
