I got new speakers recently, Def Tech BP7001sc's and was thinking of bi-wiring them. This is new to me and need some help on where to start. I was at a AV store and they had some at $5 a foot. I would like to spend less than that since I need about 35-50 feet. I tried looking at partsexpress.com but couldnt find any. On the Ascend Acoustics website (I think) I believe they had some for around $3 a foot. I would like to keep the cost down just in case I dont hear any auible difference. Are there any issues invloved with bi-wiring speakers, in other words, is if different than "normal" spreaker wire except for 2 sets of conductors. Any info would be greatly appreciated.
