What's weird is that I personally swear by the Monster CI-PRO in-wall speaker cable. I've used about half a dozen other brands including Belkin and some other major brands, and I've never had anything touch CI-PRO.
I mean, everything else from Monster is pretty ridiculous, but looking online I could pick up 500 feet of their 14/2 cable for under $150 and the cabling itself not only uses a very high strand count to maintain flexibility, but the jacket flows easily through holes, is extremely flexible, but is tough enough to not easily tear - yet whe you strip the cable and wiring, it does so cleanly.
This is within 10% pricing of almost all other brands out there, and less than some of the underperforming options.
The audio quality? Identical to everything else! So, I'm not talking about everything else, just the cable itself and the design of that cable - and just the CI-PRO cable.
I should point out, that despite their high price, at least most people do get a decently made cable. Sure, they could have saved a fair bit of money with Monoprice or BlueJeansCable - but at least they aren't getting hurt on both product quality and price... just price. Unlike, say... Bose - where it is most definitely a lose-lose.
