Hi Paul,
I had to go through similar cable overhaul after I switched the speakers from Thiel to KEF 207.2. I demo'd many before settling down on Nirvana SX for the speaker cable. Other good alternatives are JPS Aluminata or Nirvana Vahalla. JPS although great match is too pricey and Nirvana, although fast and detailed, doesn't give the depth/body of sound like Nirvana. I am sure there are others but for the gears you have, you do need to have good cabling to complete the system. My whole hearted recommendation will be Nirvana SX, coupled with Vahalla Norse jumper cables to get the best of both Nirvana and Nordost. (make sure you ditch the jumper cables that came with the speakers. It is critically important) ;-) I found above cabling changes brought such a life into KEF 207.2. Contrary to some, I find cables as important and you do need to move up in order to fully enjoy what KEF 207.2 can deliver in terms of sound.
