I just purchased the Polk RTi70 tower speakers and will soon be buying a receiver to go along with them. I was thinking of the Kenwood VR-6050 for right now, but I'm not sure. I would like to know what gauge cables would be best suited for these speakers? Someone told me 12 or 16, so I'm wondering if anyone can confirm it. Would I need some sort of special plugs? I've been recommended banana plugs. Can anyone explain how these work? I also have some pretty cheap rear bookshelf speakers, and I would probably need 18-26 ft wires for those. Any suggestion of what gauge? No center channel for right now (and I'm selling the free subwoofer that I got when buying the speakers... PSW 202 won't do it for me) And finally, I do not want to buy these online as I want to get this set up as soon as possible. What are some stores where I can get medium grade or so wires WITHOUT getting totally ripped off? I don't want anything high grade, just something that will fit into my budget and still provide decent quality. Many thanks for anyone that can help me out here.
