Actually, you should upgrade all the way to the Transparent Reference for those speakers. Look for a good deal on a used pair. The ultra would be fine to but the Reference is better.
I have B&W speakers but I use Reference cables for every connection in my system and it is absolutely worth every penny.
I thought $1000 was too much for a pair of cables as a matter of principle--before I tried the better Transparent stuff. You have to think of every cable in your system as a component in front of your speakers--especially the digital cable if you use one. It will probably be a major improvement.
