Negative feedback Amp=more faithful reproduction?

Negative feedback (NFB) vs zero negative feedback (ZNFB). There seems to be unsubstantiated contention that ZNFB amps sound more realistic. I know this is an age old debate favoring the ZNFB design, but I think most audiophiles have never bothered to look into this matter and believe the advertisements and proponents of zero NFB design. I have been in that camp until recently. My own experience and research into articles on this matter leads to me believe NFB is needed for faithful reproduction of music. I'm not saying NFB design is more "musical", which is a highly subjective term and usually means more euphonic or colored. I've posted a similar question awhile back, but I was hoping we can have a more evidence based discussion on this matter. Perhaps, we need clarification of descriptive terms we use to describe sound. My contention is, in general, NFB designs produces a more accurate or faithful reproduction of music than ZNFB designs. Here is a very good article on feedback and distortion:

This has been discussed many times with same division of opinions. The accuracy position has no absolute definition, nor does musicality and natural camp proponents.In the end we all choose components based on how they sound (our ears). Those who prefer the presentation of NFB designs should obviously buy them just as others who prefer ZNFB components should buy those. It's subjective and there's no avoiding that point.Trying to determine which side is right is fruitless. Buy what sounds best to you, you'll be happier.What does it matter if someone has different listening preferences. I'm glad there're multiple topology alternatives avaliable. There is no objective standard that is going to solve any thing.

Technically faithful reproduction can be measured, no? You compared the input signal to the output signal.

Charles1dad and Viridian, did you read the entire article in the link? I think he raises valid points about nature of distortion and feedback in amplifiers. We can't all be complete subjectivists here. Afterall, it's mostly hard science and technology have produced these wonderful high end products we enjoy, with a little bit of snake oil sprinkled in of course :)
