According to what Ive written above it is possible that some individuals are more sensitive to certain forms of distortion than others. If this is the case, a claim that amps are good enough may make sense to one person but not to someone else.

In my opinion amps are far from being perfect and there certainly is a problem making experiments by adding a defined amount of distortion to a system in an experiment as no system is free of distortion in the first place.

It would be interesting to assess if people can distinguish some linear amps from class D ones in a blind test situation. It would be especially fun to carry out an experiment with persons who write about Hi-fi on a professional level.

Now that I'd like to see!
Human hearing isn't perfect and it's far below levels of distortion that modern day measurements can make. It varies from person to person but anybody who can hear reliably outside of any measurement is probably super-human.

It would be nice if someone would come up with an easy to set up, valid blind test.

The best one's i've "seen" are when the listener is blind (ie does not know they are a participant in a test)
