Ray, until the VK-52SE burns in, you cannot really compare cables and interconnects. As to a $9,000 jump, I refer back to my post #27, which said go with Kimber 8TC speaker wires and Kimber Hero interconnects for now and upgrade later. The Kimbers are great bang for the buck and will re-sell easily, making this a low cost interim step.
BTW, a HUGE congrats on the new preamp!!
