Actually, I like using RG-6 quad shield better then standard audio cables. The shielding seems to be quite a bit better then anything on monster, etc. The only big disadvantage is that it's harder to lace,(stiffer) and doesn't look as cool. I used a 35' piece when i moved my subwoofer to the back of my theater and I don't have any hums or other interference. Best part is that it's cheaper then just about anything else and has a thicker center conductor (18awg on the stuff i used) and 2.25ghz. No problems using the f-connector to RCA either. I've made tons of RCA connections on Monster cable for custom installs, and using the f-connector converter doesn't add any more "connections" then a RCA style, it just screws onto the F-connector instead of crimping onto the wire directly. (bare copper center wire to RCA pin). I also like to use a little "no-ox" on the copper to prevent oxidizing before I put on the converter, just because I'm anal, lol.
