Metro04, FWIW I'm severely challenged when it comes to figuring out how long a PC should be. If one assumes that adding a particular PC improves the sound, say a six ft length, would a nine foot length sound better, or worse. Why? How about a 12 ft length. Would that be better or worse? Why? Assuming the PC is the same guage as the romex in the walls and the current is not limited by the PC wouldn't it be acting as some sort of filter for RFI etc and benefit by being as long as possible. I wonder how one determines the optimum length in the first place. Oh well, lots of questions - I'm sure there are a lot of answers. I'm just a Newbee. :-)
