Just realized I posted this on the wrong discussion yesterday...
That's a long interconnect you need. Will be pricey. If you are a little handy I'd suggest contacting Michael Percy Audio and buy what you need of his insulated Wonder Wire $2.25 a foot, and do the three braid like Kimber KCAG. Buy some Neutrik XLRs. Michaels a great guy to deal with. I've made many cables out of this wire and it's hard to beat. Put in a great movie and start braiding two 15ft pairs. Don't try to braid it all from one direction; braid it half way then start back up at the other end. Don't do the braid too tight or too loose... study the Kimber's. If you want to dress it up wrap it in TechFlex. Don't use a shield and you'll have a very open sounding cable. The braid will cancel any EMI or RFI you'll pick up with such a long cable. Just need a little soldering skills or find a friend and a meter to get the 3 pins wired correctly. Add more cable then you need as the braid will end up shorter than you think. Michael Percy can probably tell you what you'll need. It's work but well worth it. Just take your time.
Ok, here's where everyone starts the tweaking bashing. The cable is directional; Percy will tell you the same and I have used it and have experimented with it. So keep all the single stands running the same direction. Make sense?
