When I had 7200's, I used Gaia 1's with Carpet Discs and they worked well. When I moved to 8000's, I used them with Gaia 1's for a few months, but then moved the Gaias to my Subs (which also worked well) and changed to Titan Theis with matching Carpet Discs for the 8000's. To my ears, they sound marginally better. The Titans do increase the height a bit more but I feel that they look better on the 8000's and they offer better stability.
