Amp / speaker cable for 10T

Bi wiring is worth it.
MIT cables would be a great match.

The combo you are using now are a good match.

I also strongly recommend bi-wiring your 10T's. I have heard them both ways and the difference is astonishing. My 10T's are now part of our home theater setup, but when I was using them in my 2-channel audio system, I ran them with Straight Wire Black Silk runs, which were recommended by the dealer when I purchased my 10T's in '98. Expensive, but it was well worth it for me. I am confident you will hear a substantial improvement with bi-wiring, but only you can decide if the difference is worth the added expense.
