What isolation feet to use??

Funny how many approaches there are to coupling/decoupling/damping/etc. I personally hate sorbothane and firmly believe in Mapleshade's brass cone/maple platform (not butcher block)/Isoblock approach, but then I watched Pierre Sprey demonstrated the whole process before my very eyes (and ears) in my own system, so I know how well it works. Along the way I've also tried sand boxes, inflatable innertubes, bubble wrap (!), and dead balls (not bad at all), not to mention sorbothane (ugh). So, in all particulars, YMMV. Dave

Cruz128, good advice. And not just wood furniture. I used some Vibrapods on top of an amp once and they etched permanent circles into the metal surface. Never again.
