Bi Wire cables for B W 805N

I am looking for suggestions on a Bi-Wire cable for my 805's
My Amp is a Linn Klout and pre-amp is a BAT VK 30 SE. The 805's run full range with a Velodyne HGS-12.
For a reasonable priced cable,I don't think you can beat the DH Labs Q-10. I'm using them bi-wired with B&W CDM 7NT. After about a 50-75 hour break-in, they really open up.
I would definitely go with the Valhalla. It is unbelievably open, fast and controlled while still being extremely musical.
I also run my 805's full range, with a REL strata III sub, and am very happy with my Harmonic Technology Pro9 Plus bi-wire cables. Their is enough controversy and plenty of hype in the cable business, but the overwhelmingly positive reviews (Stereophile, Absolute Sound, etc.) of Harmonic Tech's line is on the money in my experience. Maybe starting with a better quality ("single crystal") material makes the real difference, I wouldn't know. They are still reasonably priced, and do show up at Audiogon for about 60% of their retail price. DH Labs do make a good quality product for the money. I use their cable for my sub, but they are not in the same league as H.T. The 805's deserve the best you can afford.Haven't heard the Valhalla. Good luck.
