Thanks for the courteous reply Shahrose. I'll look for future opportunities to compare cables and will probably get around to making one myself one of these days - having already assembled a mogami/neutrik extension cable I use with a fair degree of regularity. But the problem with buying or building first, and listening second, unless you're doing it blind, is the post-purchase rationalization phenomena that inevitably comes into play. For now, I imagine I'm more of an agnostic than a true disbeliever as to the merits of replacement cables.
I believe I'm familiar with the simple science. In fact, I'm in the process of reading through Morgan Jones' definitive tome on Valve Amplifiers right now. I simply have yet to see a single scientific article/test/or study that agrees with what you're suggesting regarding power cables. Even assuming, for the sake of argument, that electrons have the potential to flow "better" in an expensive power cable, how is it possible that an end user benefits from this in any way when that pricey cable is being plugged into a dirt cheap socket, and thereby connected to the basic electrical wiring that permeates the rest of your domicile? Let's look at the other end of the connection as well. If you have ever done a DIY project or looked at the hook-up wire used throughout the power supply of even the priciest amps, we are talking about some pretty basic wire here (even on the high end) that then typically runs through the tiny leads of a diode bridge to become DC. Your amp's wiring is not even close to the stuff vendors are charging $30/yard (on the low end) to you-don't-wanna-know/yard (on the high end) for to serve as fancy A/C cables. If I'm missing some simple aspect of the science here that gives rise to an audible difference when using high end AC cables, please fill me in... I will happily eat humble pie as the price of an otherwise free education on the subject if I'm wrong /shrug
