Don’t forget that RG6 cable uses a copper clad centre conductor made of steel. It is great for RF and other high frequency applications, but lousy for audio. Also remember that coaxial cable exposes one of the signal-bearing conductors (the “shield”) directly to interference. True high performance audio cable uses a twisted pair of signal bearing conductors protected by a layer of foil and 100% braided shield with a drain wire that is connected to chassis ground at one end only. Yes, Monster doesn’t use a dedicated shield, but their connectors and cable are still the same concept, and infinitely superior to compression connectors on RG6.
