"hi russ69: my point is that one should not trust the senses."
I use my ears, to listen to my HI-FI. I can listen to a pair of amps and tell you which one I like better. It may not be better by measured criteria but I can decide if it sounds better to me. If the two amps under test are very close in sound, then I will have to spend some time with each one. Sometimes a long time. After a while and some evaluation, I can pick the one I like.
I trust my senses, if I have the time to test things out. After all we are using one of our senses to enjoy HI-FI. Can I be misled? Sure, but not for a long period of time. I trust my ears. I surely can tell when something sounds like crap. I don't need any supporting documentation for that.
