I know I know... everyone has their own opinion... but I need some advice. I am going to have to buy some speaker cable soon. If my choices are Radio Shack, Best Buy, or Circuit City, what should I buy and where should I buy it at? I know I need 12gauge, thats all I know. I think i will just buy a spool of 100' just to make sure I have enough. Also, I have Athena F2's, and the center channel. Do I need banana plugs to connect these to my speakers? PS - I have read the faqs on this site.
