About to purchase some wire for my HT, and came across a slight dilemma. I was wondering what is the difference between the following groups of wire, and which is recommended for my application (from cheapest to expensive): 1) Partsexpress.com - 12gauge Sound King Speaker Wire, zip cord. Part #100-155 3) Ramexlectronics.com - Liberty THX certified Speaker cable, 1 pair of 12 AWG wire. Part #12-1P-WHT-100 2) Ramelectronics.com - Canare Star Quad speaker cable, 4x14AWG cable (11 AWG paired). Would be used in a paired situation (to create 11AWG). Part #4S11-100 I will be running the wire through the attic and then down interior walls for a short distance. The mains/center will each have a run of approx 30-40ft, and the rears will be 15ft and 25-30ft. Not interested in a Bi-wire sitaution at this time. Also, what disadvantage is their to running zip code through walls instead of "in-wall" rated cable? Besides any local fire codes, are there any negatives on the sound quality to account for the higher cost of the bunlded wire?
