I recently had a McCormack DNA-0.5 amp up-graded to Gold Revision by SMc, and during the up-grade process discussed vibration control w/ Steve McCormack. Steve recommended the "Shakti Stone" placed on top of the amp over the transformer-- or better yet placed directly on top of the transformer. I haven't tried this yet-- those things are sort of expensive-- but eventually I will. Anyone tried the Shakti Stones?
Right now I use a pair of 10 lb. lead deep sea fishing weights sitting on boards on top of the amp (to spread the weight more)-- can't actually tell if this helped sonics any but it added 20 lbs. of mass. I have the amp sitting on a 2 1/4" thick Boos Maple cutting board-- a very nice improvement. The maple board sits on cork/rubber footers by A'Gon member Rcreations. This was an excellent combo for this amp. Cheers. Craig
