xStream speaker cables and B&W 804s

I was wondering if anyone has experience with a combo like this? I have heard the B&Ws described as bright (I love them as they are) and I have heard the Xstream bi-wires described as warm. I am thinking the combo might be a good balance. My other thought is a set of Wireworld Equinox 5s, but not bi-wire. I have a Parasound preamp and amp with Wireworld Polaris 5 interconnects.

Any comments appreciated.
