Revel Salon 2 Owner - Bi-wire or jumpers?

I tried bi-wiring (Transparent Reference MM1) and the result is so so. Actually the single wire Transparent Reference MM1 is a bit better.

I tried Analysis Plus Big Oval Silver jumpers and the result is almost the same as the stock strap. By the way the stock strap is made by WBT. I am thinking Revel has done a good job optimizing the Salon2 with single wire configuration. What do you thnk?

If you use jumpers, what jumpers yield good results to you? Thanks.
