I don't recall the specific associated electronics, but the system had Avantgarde Duos and tube electronics. The Ultras and roller balls worked well under everything, except the CDP. It's not that the system sounded bad, just leaned out the sound a touch too much. I think results are system specific and a matter of "tuning" the sound. It is BECAUSE these things are so effective and they do substantially alter the sound that results will vary substantially.
I personally use Ultra platforms and rollerballs under my amp and linestage. I also use Svelte Shelves under my speakers. With my current CDP (Naim CDS3), these devices help a little, but I actually cannot practically use them because there is not enough room in my rack (the player is a top loader).
I have seen the Symposium demonstration at a dealer and at CES. It is quite impressive.
