I have heard that you can make high quality cables by using RG6 (? I think that is its name) and F-connector to RCA male. Is the quality comparable to Monster cables? I have Component 2 video cables, and its a big difference from composite or even generic component cables. Just wanted to know if this works for any cable type: audio LR, composite, component, digital coax? Any problems/advantages with longs runs using coaxial cables?
