In other words, those that use global negative feedback to "correct" events that have already passed. TIM, anyone? Especially bad when the output filter/transformer is in the loop.
Honestly how could that even be proposed as an improvement in fidelity to the original signal when all it can possibly do is change it?

"correcting" and re-correcting on each cycle. These newly-created errors eventually reach audio time scales and are heard as TIM distortion.
Such errors are perfectly acceptable when using feedback theory to control a potato chip fryer or an airliner autopilot system, as the steady state operation is what counts. Enough ears can testify, however, that the same theory may not be optimal for reproducing transient musical signals in the most pleasing manner.
I can't argue with your subjective impressions so we can agree to disagree...
