Speaker cable recommendation

Hello all.
looking for some recommendations for a speaker cable. I know they are very system dependent. So here we go.
my system is as follows:
plinius 8100 integrated amplifier 
musical fidelity cd player
rega planar 25 turntable
B&W P6 speakers
my interconnects are Kimber kcag, cardas neutral reference, and audioquest lapis
im considering Kimber 8tc, Cardas cross, signal cable, etc.
im looking for a bi wire setup.
thanks all,
best regards,
Shawn
