Hi Mikey,
I currently use Cardas interconnects, clear, golden reference, neutral reference with the matrix 60. Years ago I had an all MIT cabling setup, but for some reason I was not satisfied with the sound. I found that Cardas or Wireworld was more sonically accurate as interconnects. I don't know whether that is true now. At a later time I will try the new MIT interconnects to see if they are better. Right now I am using Magnepan 3.7s for speakers.
