A few points for you to clarify, first"I have seen several measurements in Stereophile where amps exhibit crossover distortion and according to Lesurf this is not fixed with negative feedback."
which ones? Secondly crossover distortion is totally different mechanism, it is never addressed with feedback. Since you have raised the issue of crossover distortion, I will refer you back to what Earl Geddes said to you on the subject a while back.
"But I do agree that some forms of crossover distortion caould be quite audible even on "poor" colored loudspeakers and yield a fatigueing situation. But I would describe this amp as "broken" in that case. In any decent amp this would more than likely not occur. "
An amplifier with audible crossover distortion is broken, broken in terms of design.
"If the amp is stable enough and distortion low enough then none is likely the right amount. "
What is not in dispute is that the open loop linearity of any amplifier is no where near its closed loop linearity, so to a large extent you comments are academic, if objective accuracy is a goal for the amplifer designer, as the article you quote states, that are guidelines to using feedback and as long those guidelines are observed, the beneficial effects of implementing feedback in the amplifier design overshadows the disadvantages.
