Cable life

Thanks for the advice. I'm powering a pair of CM4's with a MA6450 integrated amp. The system sound is good, the room acoustics are great. In the future I'd like to move to the 800 series B&W or look around, but for now I'd like to upgrade the cables. I'm currenty using $2.50 ft. Monster cables bi-wired. I heard this Mcintosh with Nordost Blue Heaven cables and Verity Tamino X2's. Sounded awesome. Not sure how Nordost would pair with B&W though. Will look at Acoustic Zen. Thanks.

Thanks Audphile1, From some of the pricing I've seen they may be a little out of my range but I'll keep looking and try to demo them.
