I agree that higher end MIT speaker cables sound great with Thiels, but I have found the opposite to be true of their less expensive speaker cables with my 3.6's. Anything from the AVt1 on up should be okay, though. However, I am using Cardas Neutral Ref. speaker cables in my system, and I am very happy with them. For interconnects, I am using a mix of Cardas Neutral Ref. and Quadlink 5C for source to pre/pro, and MIT MI-330 Series 2 interconnects from pre/pro to amps (Theta), and again, I am happy with this setup.
