I'm aware of all these facts. I've heard first hand cables that make a difference in sound. Was the difference enough to make me want them? Ehh the Nordost Valhalla at $8,000 for a 3m run was not, but there was a noticeable difference over the $600 Blue Heaven line.
Anyone who says cables do not make any difference either doesn't have a system capable of prducing sound quality good enough to hear it, or their ears aren't that good.
I use Nordost cable in my audio setup, but I don't want to spend that much and don't think the difference would even be that noticeable with Home Theater.
Basically I was asking if anyone here was running any biwire setup and what they were using. Sorry to open the can of worms heh.
