Speaker Cable for Cary CAD-808/Proac Response 2

Please help me with this. I am changing my system due to space considerations. I just purchased a pair of Proac Response 2 (to replace my Spendor 9/1) and the Cary 808. I will be using an Aragon preamp with the Cary until I can change to a tube preamp. You can look at my virtual system for more details.

Thanks for your help.
