B&W 801 speaker cable suggestions

I recently purchased a used pair of B&W N 801 speakers and wish to upgrade my speaker cables to something that would complement these speakers. I am currently running MIT Terminator 2 single wire cables at this time. I am using a Sunfire Ultimate receiver as my main power source and using an Arcom Apha 8 CD player with cardas Quadlink 5C IC. Some of the cables I am considering are 1) Tranparent Music Link 2) XLO Ultra 12 3)Cardas Cross.I am thinking of going bi-wire with the above cables.

Any thoughts or suggestions.

Thanks, Mike
