In my mind, it would seem that as long as your power filter is not hungry, and is getting all the amps and joules it requires, that just applying a more expensive cable of the same size would be negated by the filter. If it did make a subtle difference, then the filter would do its thing, and the same result would be present on its output. I'm sure you've heard the theories about how modifying the last 3 feet of a wire than goes back to the power company, and all over the neighborhood, is just wishful thinking. But what comes after the filter! Now you've got control over that! Keeping that clean signal you've created intact with large enough conductors to prevent any restrictions into your gear, I can fully see how quality wires can help! But, this is all supposition, I would be very interested to learn if indeed you did hear a difference by upgrading that cable. What we think is happening, and what actually happens can often times differ, there are variables we are not measuring involved, otherwise no wire could make any difference. What was that website? The Cable Company, I'm not sure if they still do, but they used to have a loaner system that allowed you to try cables in your system, and return them if they weren't right for you. I just looked and they do have a slew of power cables available. And of course I'm sure you'd get better prices here on Audiogon, and just buy and resell any that didn't please you.
I know I've heard others say and swear that their filter's power cord made noticeable differences, and I've heard just as many others say the opposite, no way to know except conduct your own experiment!
