"with cheap cable you get all the radio frequencies traveling down it, the more expensive cable is designed to avoid that. " Huh? I've been into hi fi for donkeys years and I've never heard that one. A chunkier cable is preferable, no doubt. This is because current is conducted on the surface of the conductor so chunky, multi stranded copper wire offers a bigger surface area. But it's all carrying electricity for goodness sake. Where did the "radio frequencies" spring from? If you're saying it's acting like an aerial, that may be so, but;
old fashioned AM aerials are a chunky piece of ferrite core (iron to you & me) with a coil round it. The chunky cable will pick up just the same as the thin stuff.
any such current picked up will be utterly minute compared to the tens of watts your amp is pumping out.
short of sticking electronics into the cable it's not going to filter anything!
Reminds me of the dingbat who asked if some cabling was Millennium compliant.
