Best speaker cables for B&W N801

B&W 801N's with McIntosh MC501 monoblocks and C2200 tube preamp.
B&W has an impedance spec of 0.1 ohms for the cabling to these speakers.
I'm thinking 8TC/4TC biwire.
Your recommendations would be appreciated.
I use two sets of Harmonic technology Pro 9+ in a bi-wired configuration with a Mac C2200 and MC2000 with excellent results. This combination provides great dynamics and detail while maintaining a full and vivid midrange that makes vocals particularly real sounding. Good luck!
