I found that using a PS Audio power cord instead of the stock cord on the I5 resulted in a huge improvement - more than any interconnect change has yielded for me to this point. I was quite surprised, as I wasn't convinced that the power cord would make a noticeable difference.
Given that the I5 will be drawing far more power from the wall than the Equinox, I'd start with the I5 power cord first of all, but would be inclined to change both cords. Don't know the cost of the various models available, but would presume that Cardas must be a good choice too since Sim has bundled Cardas cables with their "LE" models in the past.
I would presume that you're in for some good listening with your setup - that should be a great combo.
