Negative Feedback a deal killer?


If an amp employees negative feedback is that a deal killer to you. I have had both zero negative feedback and 5db nfb amps and I much prefer the Zero's. I am looking at a Unison 845 amp and it has over 10db nfb. Or should one just listen and shut up.
Your thoughts are appreciated.

Unsound, My bad and sorry I forgot that I'm not well known as Ralph of Atmasphere or Charles Hansen of Ayre or Nelson of Pass Labs, and I would never dare to even compare to these exceptional designers. I'm just a rookie. So I thought by my moniker it is known that I'm a manufacturer. I believe I registered as manufacturer and not private user. First Let me say that I don't usually post much in any forum. If you check, I might have less than 5 posts through the years in Agon, and when I actually post, never have I bragging and/or pushing my own product. At any rate, You're absolutely right. Rules are rules and we need to follow. As for negative feedback or not, all I can say is negative feedback doesn't make it automatically BAD, and conversely, NNFB does not automatically makes it GOOD. It all depends what load and more importantly system as a whole. and even more important, listener's preference. Of course I can go on.

Unsound, the way you described THAT GUY sounded like it is me though I'm not sure. I have designed conventional class A for many years. In fact I still have a 100watts pairs of monoblocks and an 85 watts stereo class A. The link show my 85 watts stereo class A which I used to drive the Scintillas for years.

Dob, Thanks very much for the understanding and again I did not mean to offend you in anyway.

Brml, if you have an inefficiency and/or tough load speakers, NNFB may not works too well. Then again, It is all up to your ears.

H2O, no apologies necessary. We might be new to you, but you're not new to us. Don't underestimate yourself, we don't. Again, welcome!
Hello Unsound,

You wrote:

"As I understand it great deals of negative feedback are often used in Class D amplifiers. One poster has already commented that since it is done at much greater speeds, the lag is inconsequential "

- which I understood that you generalize all negative feedbacks in class D amlifier. However, since you said that you do not believe that then my sincere apologies for misunderstanding.

Cheers
I haven't read every post in this thread, but has anyone mentioned GLOBAL vs single stage feedback?
global, from output to input while other designs apply feedback at a single stage or a stage-at-a-time.
I can understand the time dependent nature of feedback, but can't that be helped by more....limited applications?
