Bright Star vs. Symposium

Has anyone compared the Bright Star air mass isolation system to the Symposium super platform? I'm looking to isolate a transport, DAC and tube preamp.
I had the Bright Star and sold it to purchase the Symposium. They are both exceptional units however, I feel the Symposium is a better design and more simplified compared to the Bright Star. Quite honestly the Symposium just looks better. Either way I highly recommend some type of isolation base for your digital really does make a difference.
I just purchased 1 Ultra, 2 Super, and two Svelts. They are great. The most improvment was when I used them under the Sonci Frontiers Transport 3. Not much difference in performance between the Ulta and the Super. Go for the Super.
