Cables for B&W and Rotel system.

For sure try to find a warmer sounding cable to tame down
the tweeters on those speakers. MIT cables usually work
well with those speakers.

Synergistic Research Alpha Active are good if you are on a budget. The Signature 10 active are where I would go for the next step up.

When I was a B&W owner, I tried hard, very hard to get B&W to answer this question for me. No real luck. I asked the question in many ways including what equip. B&W used @ shows.
Thru some painful digging of info, I found that B&W had/has a soft corner for Kimber. I *think* that there is collaboration between Kimber & B&W in England (maybe even Europe).
I personally used TARA Labs Master Gen II with great success. I still own these cables & use them with my present speakers. FWIW. IMHO.

kimber speaker cables works very well with B&w. I've tried audioquest slate, acoustic zen hologram ii, synergistic 10x, bifocal xl is the best. detailed, smooth, lots of texture.

I second the Tara Labs recommendation. I too own B&W speakers and Rotel equipment. I've used Tara Labs, Monster Cable, and Acoustic Zen. The Tara's gave me a bigger soundstage, and much better bass response and fullness than anything else I've tried. They also tamed any kind of harshness to be said about the metal B&W tweeter, without rolling off the top end or ruining the the 'air' or openness in the treble region.
