For sale 

Symposium Precision Couplers. Can be used on there own as feet or attach them to rollerblocks or platforms. see my other listing

I have 6 sets available

I tried various feet & isolation over the years and in my honest opinion Symposium are right up there. Absolutely no colouration to the sound whatsoever. Something I can’t say about other similarly prices products out there.
