Don't be afraid to play with front to back tilt. I have the X5's and I have a pair of Herbies Audio Lab isolaters under the front feet and Gaia's in the rear. Gives me about an inch more down angle tilt. Its perfect for my listening chair and my height. If you haven't already, play with speaker placement from back wall, and inward tilt angle also. Adjustment of that first reflection off the rear wall with dipole speakers is very important.
