Hi Tricka, It's good to catch you here again, I'm using the Symposium Rollerball " HDSE " Jr's underneath mine. Back when I owned a WTL Classic mk V I used the Marigo Labs Micro Suspension System underneath it sitting atop a Signal Guard II to great affect. As I pride myself on very very much being into Isolation Devices and am quite taken with Ebony Wood devices from both Shun Mook and Yamamoto Sound Craft - as this was something that I picked up on while in Japan during the mid 70's, they're more into isolating each and every component within their system as a means to voice them accordingly. Something to do with " Tone Woods " before it became popular in the states during the late 80's. The Art of Refinement I'd say. Cheers, Oscar
