Bruce, Mo may have misplaced a zero, since my calculation indicates that the improvement from bi-wiring(aka "buy-wiring")is 0.0014dB.

More seriously, Blue Jeans is a very reputable no-nonsense outfit, remarkably so for a cable supplier. Their prices are a little higher on some items, but certainly aren't outrageous. The wire that you're considering is thicker and stiffer than necessary except for very long runs, but of course it does the required job.
