MI Terminator 2 Bi-Wire upgrade

[parthadutta]

I have these excellent stereo MI Terminator 2 Bi-Wire speaker cables. My system comprises of Audio Note DAC, Quad Pre 77, Quad Power 707, Quad 12L2. I'm very happy with the MIT, but would like to upgrade. Can you suggest appropriate speaker cable upgrades for me? Thanks

Nice setup Mr. Dutta
Sorry for a novice question, but what does the box have in it through which the cable is passing?

Coupler input module. The input module is designed to minimize the extent to which the cables reflect energy back to the source component. This results in increasing the number of articulation poles available for the biwire speaker cable.
