Currently I am using cheap RCA brand 16 awg speaker cables. My receiver is rated at 60w @ 8 ohms (Denon AVR1601) but my speakers are a nominal 6 minimum 4 ohm load, so I am pushing 90-120w through them. For purposes of this discussion, I'm talking about my fronts and center only - they are Image 2Bs and Image 8c, respectively. For a bit under $40 I can get Pro series oxygen free cable from AR in a 50 ft spool. While I do not believe in paying $3/foot for cable, I had a hard time believing that speaker wire has absolutely no effect on sound, as some people suggest. Will going from this 16 gauge to 12 gauge give me a noticable improvement?
