Bill, you are telling me that what I can do on a regular basis is impossible.
You're not the first to tell me such & such is impossible. I have had industry insiders including designers, manufacturers, repair technitians all tell me at one time that differences in sound pertaining to cables was not possible, or that it was negligible. To a person I demonstrated to them in my room that they were wrong - politely, of course. I am not naming names because if I were in their shoes I likely would not want my name associated with such a situation publicly.
In one case it was in regards to power supplies, as the other party said power cords cannot influence the sound of a power supply for an electrostatic speaker. Well... when in my room he heard differently he admitted that yes, power cords could influence some types of power supplies.
BTW, prior to the demonstration for him others taking his logical tack threw their derision my way, but amazingly after he posted that I had been right they changed their mind based solely on his testimony.
Another manufacturer proudly stated that he used cheapie cabling because they didn't matter that much. Well... after a demo in my system that manufacturer bought new cables for his audio show system.
You can feel free to doubt, but as they say, "While some are saying, 'It can't be done,' others are out doing it."
As for you, Rok2id, I recall you stating that you can't get your hands on the majority of equipment by which such things would be tested. I believe you have previously admitted that you are arguing your points from logic, not experience. I used to do that, and I was wrong much of the time. It takes only one or two experiences to show how far off base your logic is from the reality. Occasionally you will see in the threads a theme to the effect, "I just tried different cables," or "There IS a difference in cables..." IOW, they finally tried and found out how easily heard such things can be.
Similar the differences between a 1M and 2M interconnect.
I am not suggesting that hearing the difference would be as easy as falling over, or that even the average audiophile with a moderately capable rig would be able to discern it. In general terms you would need an extremely fine rig, perhaps in the $80-100K range and up. It has to have truly exceptional definition and clarity. If not you likely will not hear the difference. Now, simply because most people don't experience it does not mean it's not possible. Is it a more elitist excercise? Yes, because it pertains to a level of peformance most people will never achieve. But if an audiophile with good hearing were to compare they would hear it.
