Homedesign: It is too bad that you didn't apply as much logic or research as you did passion to your post.
Not all components are load stable, nor do all cables present the same feedpoint impedance, even when terminated with identical electrical characteristics from identical components. As such, cable changes can and are component / system dependent. On top of that, some of these differences can both be audible and measurable.
If you doubt this, try talking to Frank Van Alstine* about this subject. Frank is both a designer / manufacturer and one of the most out-spoken individuals in audio when it comes to cables and "snake oil". Ask him if components from various manufacturers all respond identically to cable changes. I'm talking about cable changes that result in variations in the feedpoint & load impedances that they see. Since i already know his answer and the truth about the subject at hand, i'll be waiting for your enlightened response once you delve further into the subject and re-educate yourself. Sean

PS... Since you seem to be a fan of his, try emailing Siegfried Linkwitz and see what he has to say about the subject. If he's ever done any REAL testing on the subject with a variety of components from various manufacturers, he'll share the same thoughts on the subject that Mr Van Alstine and i do. That is, cables should NOT affect system performance but most circuits aren't designed / built well enough to achieve this goal. Therefore, their performance is altered to one degree or another when cables are changed.
* I know that Frank knows all about this, as he took the time to educate Julian Hirsch about the subject.
