This is kind of like the debate that some reviewers had with EE's when digital first came out. The reviewers claimed that there were very audible differences between digital signals. Of course, the EE's stated "digital is digital", etc... because it all basically measured the same. Or so they thought.
Of course, J. Peter Moncrieff was one of the "golden ears" that said that he could hear "darker background, greater dynamic range, sharper detail, etc".... when comparing one CD player to another. Even though the frequency response was linear and every form of distortion was low, there were OBVIOUS differences in how they sounded. The funny thing is that he went on to document via electrical measurements that what he was saying and hearing WAS true. While one player had deeper nulls and higher peaks, faster rise and fall times, sharper images with less distortion, etc... the other was clearly not as fast or clean. Moncrieff even went so far as to publish photographs of waveforms taken via his o'scope for direct comparison to demonstrate that "not so subtle" and "audible differences" DID exist and ARE verifiable. That is, IF you knew how to do the proper tests AND interpret the data that you collected.
There is an analogy that i use on a daily basis that seems to fit here: Just because you have a hammer and a saw, that doesn't make you a carpenter. The same can be said for EE's, ME's, technicians, etc... Just because you have a piece of paper called a degree or a license, years of experience, etc... does NOT mean that you know or have seen it all. As such, the best people in ANY field are the ones that think they know very little and are always looking for explanations of how & why. NOT the people that say "that's impossible".
Like i said before, just because we can't "measure it" today doesn't mean that the differences didn't exist yesterday. I can think what i want, but that doesn't make it "fact" or mean that others are wrong for not agreeing with me. It just means that it is my opinion and only worth the value of what others put in it. As such, neither Abe nor John Dunlavy nor i are "right". We simply have our opinions. Put your faith in what your ears, eyes and heart tell you. God didn't give us all of these senses and the amount of intelligence that he did for us to throw it away because we don't know exactly how something works. Sean
