Bomarc,
I've always thought as you; as long as the gauge was correct for the current what's the reason for all the rest. But the issues of Xc and Xl, capacitive and inductive reactance, as well as EMI must be considered at the level of resolution my equipment can provide. My previous system hafler, marantz and Boston Acoustics, in my opinion, did not warrant even concidering upgrading the "wires". I think I owe it to myself to check out the "high end" stuff and see if it makes a difference. If not, no biggie. The education will be worth the minimal cost. But, if so, "!@#$% A" More good tunes for me, my family and friends.
Thanks for the response.
