Why do audiophiles shun feedback in amplifiers?


I've owned several very highly regarded tube amps. Some of them allowed adjustment of the amount of negative feedback. I've always found some degree of feedback improved the sound...more realistic with tighter bass, dynamics, better defined imaging, etc. I have found amps with less or no feedback sound loose and diffuse with less dynamics... I know you should design am amp with excellent open loop gain before applying feedback. I can see the use of no negative feedback for low level amplification (eg, preamp and gain stage of CDP or DAC). So why this myth perpetuated by audiophiles and even many manufacturers?

Well there's a couple years of intense study in electronics engineering in a nutshell! I'm looking forward to a lot more analyses geared toward practical utility. Am I asking too much? Lets keep this ball rollin guys. Nice change. Is that a lyric?
Are you suggesting that there is a correlation between the descriptive definitions of musicians and various gear designers and consequently their result? Or just the systems that musicians put together vs. the rest of us?
But at the end of the day, do we not settle for what pleases our ears? It's a given that language itself is the largest barrier to communication. So even if we were cavemen running around with clubs, grunting our needs, we would still end up with what we want. Miscommunication just makes things take longer. Our individual perceptions of terminology used here may have us completely misrepresenting our gear but not necessarily preventing us from arriving at the same destination.
Charles, in what sense is your goal a template? How and why would anyone disagree? What has the contention been so far in this thread? I seriously don't mean to be provocative but something's gone over my head here and "I don't know what it is".
Oh. I guess the entire chain of events is dependent on each link to arrive at the desired destination. I never looked at it that way. Makes a lot of sense considering the limitations of each component. But then you are limited by the recording source, aren't you? The best you can hope for is a general level of synergy. Then again, isn't that everyone's goal regardless of their point of view? Is yours a "method" or simply a different mindset? No matter one's approach, it seems in the end, we all find the light at the end of the tunnel. What's good is good, no matter how we formulate it. I can understand the stumbling block in relying solely on reviews when assembling a system. However your ears don't lie. Having to settle once money is spent is obviously the worst that can happen. Sad if we only find the light at the end of the tunnel when we can afford to. I've recognized a few heroes on this site so far. Not enough going on to single them out vs. the bs. though.
