Bomarc ... I'm pretty much in agreement that so far I haven't heard of any audio phenomena that could not be explained scientifically, including the science of the perception of sound. I must have miunderstood your previous post because I think we're in close agreement.
There have been many times when I've managed to improve the sound of my system by making a change that I was convinced would have no effect, and then afterwards I have been able to think through why it has worked. For example adding an external DAC to my mid-fi CD player made almost no difference, even though the DACs, power supplies and output stages were much better in the external DAC. Then I added a monarchy DIP and suddenly the external DAC sounds much much better. I then did some reading on timing jitter and it's pretty clear what happened. Same with interconnects, speaker cables etc etc.
