Thanks everyone for your advice. I wish I were able to take advantage of the Cable Company's trial programs; unfortunately, I'm in Canada, and they don't offer it to anyone out of country. I have to admit I'm reluctant to try any silver cables ever since my first experience with the QED Silver Spirals; these cables were so bright in my system that I swore I'd never use silver cables again. However, I was drawn to the very upper most 'fragile' treble frequencies that they did offer....that copper cables, thus far, have not been able to produce...Thus, my search for silver cables with bass response...
