Looking for the right interconnect

Ha! I'm building an entry-level system for a good friend from the new NAD C541i to the same Audio Refinement Complete, to baby Spendors. I just bought him Blue Heaven, and maybe a Kimber Silver Streak to start (tuner to amp too).
Hope our results are better than Philjolet's!
I suspect that resolution won't be a problem, but that open-highway leanness might be. Any suggestions for a sub-$100 used detailed but WARMER cable if we need one?
Harm Tech Truthlink is my favorite rounded cable for FM birdies, etc., but at $150 used it's a stretch....
Thanks.

Why do recording pros use Canare at $0.34/ft to make GREAT mic and IC cables? I just finished rigging up 25' mic runs with this stuff into a Grace class A ultraflat, ultradetailed pre, and then to my Alesis Masterlink. Then came the decision as to how to connect the ML to the Aleph P pre? I made 1/2 m Canare XLRs, sold my Red Dawns, and just bought some Blue Heavens. Which will work best? Why do pros LOVE this cheap quadlink Canare? You can even get 1/2m wired sets from Markertek for $12.95! Does anyone know how these sound in the audiophile continuum? I must say that my Steinway actually sounds BETTER in some ways than when played live! I know this is heresy, and that it's due to careful nearfield mic placement, but you can't convince me that these Canares don't do it right. Jeckyl & Hyde again....
