I have been doing a little experimenting with my system lately and I would like your opinions or more specifically what material combo works best for you. I.e. do you use copper, silver, or other throughout your system (interconnects, speaker cables, jumper cables/plates), or do you mix them up? I have had the opportunity to mix and match quite a few cables/interconnects/jumpers and I have arrived at a combination that I really like. Copper interconnects, copper speaker cables, solid core silver jumpers. I am not looking for brand specific cables, just what material combination works for you and why. Greg
