The Kimber 4 and 8TC cables are some of my long-time favorites.

I would run the 8TC to your 802s and save the 4TC for another stereo. Or try just the 4TC as you'll cut the capacitance in half.

I can see how it would be tempting to biwire. Hell, try it out! It might not sound too bad. If you do, keep the jumper on the negative posts connected. It's a tweek I read on the Cable Asylum that I found beneficial.
