speaker cables for b&w

What speaker cables are good with b&w speakers? On b&w website they recommend speaker cable with 0.1 ohm impedance. Does anyone know if this is important?
Probably need to know which B&W your talking about to give a accurate answer to yuor needs.....
I've used audio quest and Transparent audio cables with much success with my B&W speakers
I used www.pothaudio.com when I had my B&W's with great success. Also try analysis plus I liked them because they were neutral.....
most of the speakers on b&w webiste required 0.1 or 0.2 impedance.
