Best isolation device for a tube pre-amp

Use a good,solid stand.For tubes get Black Diamond Racing Cones #4's For S.S. try the #3'sI tried Vibra-Pods,stock feet and J.A.Mitchell cones.The best by far were the B.D.R. cones.They opened up the soundstage,deepened and tightened bass and just sounded nicer overall.You can pick up 3 here on AudiogoN for $45 used.. $60 new.....dave99

An empty box Of Montecrosto #4 works well.Put the cigars in the Humidor and fill the box with silica sand.Place it on top of the pre amp.Works great.

Aurios MIB by a long shot. And while you're at it bypass any crappy mdf shelf with a maple cutting board or block of maple.
