I agree that there is a difference between 10$ cables and 100$ cables. I did many many tests with cables form 100 to 1000$ and more (A-B Blind test) and I can not ear any difference. Sorry, I can't.
All my Rotel components are connect with Monster Cable THX 1000. Got them on ebay for 25$ each.
If you want to really improve your system, put money on room enhencement, not in cables.
Anyway, it's always funny to read about cables...
