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.

If we all followed that advice, there would be no forums on Audiogon. If only the wise did, they could only learn from the unwise :)
It would have to depend on how much positive feedback the amp has received, wouldn't it? (Sorry -- a little Audiogon sales joke there.)
I have two sets of amps that use zero feed back (Atmasphere, Electra Print), one amp that uses minimal feedback (VAC), and another amp that uses moderate feedback (Music Reference). I use and love the sound of all of them in my system.

I suppose we might also clarify whether the discussion is about global feedback, local feedback, or both. While we're on the topic, when a company markets their product as a zero feedback design what are they really referring to? It's been my understanding that this generally refers to global feedback only. I had an interesting conversation with Roger Modjeski on this once. It's a topic you don't want to get him started on unless you have the time and knowledge to keep up with him.
