I don't think you can make the generalization that all vacuum tables need an additional clamp,to dampen resonances.I doubt that the Walker does!
My friend,who owns my exact analog rig(Cosmos/Transfig./2.2)tried my little "cork mod",which I mailed to him.Although he confirmed a really nice improvement in sound(and promised me a nice bottle of wine),it is the Sota Reflex clamp,that seems to be the culprit(this has has stayed unchanged for about 15 years,while the tables have morphed into greater designs).This seems to be reflecting feedback,which the cart. is picking up.The clamp is actually quite resonant,and rings when struck with a finger nail( at least mine does).By placing some kind of dampening material underneath,this effect was greatly reduced,and made a really nice improvement to the sound.However it did make sense,to me,that one could re-voice the vta/downforce/fluid(combo),to a bit of a higher degree,once this slight "clamp induced signature" was reduced.I cannot say completely eliminated,as I only spent one listening session with the improved results.
Best to all,and hope all is well!
Also,Larry,hope the new super tweets are working out.I read the web-site,and according to Townsend these models apparently expose a real weekness in the Tannoy "super tweeter" designs.
