What is the best speaker cable for Wilson Sabrina X?

I use Morrow Audio MA7's with my Sabrina X's. They seem to work well with them, although I have heard good things about the Transparent Audio wires.  I listened to the Sabrina X's with some Transparent cables that supposedly cost $65K, so that is   a stupid comparison, and. stupid waste of money.  Not to foray into the cable price/performance argument, but intuitively, it seems pretty dubious that 65K speaker wires sound appreciably better than less silly-priced cables in the $5-10K range.

Since my post above, I have switched from the Morrow SP7 (which was a good cable) to the Shunyata Alpha speaker cables.  There is a noticeable and very positive difference with my Sabrina X's.  I highly recommend that combo!
