Cones, spikes, or vibrapods for heavy sp

I use Walker Audio Valid Points under my 140 ld Genesis Vs. They come with discs that the spikes go into. These are fantastic. I also use them under my amp & preamp. Not cheap, but Pierre Sprey (Mapleshade) uses a set under his Pianos legs! Avail from www.audiotweakers.com

Vibrapods were a failure under my speakers. When I first tried them I was very impressed with a sense of ease in the treble and bass. But over time I found the midrange was somehow uninvolving. When I took them out, the music came back - very odd. Apart from this problem, the Vibrapods seemed to reduce cabinet resonances, and I think that is the point. The best solution is very rigid coupling to the floor IMHO - but the problem is that the energy still has to go somewhere. Rigid coupling seems to give the greatest level of detail, but if the speaker cabinet is not great, the downside is more intrusive cabinet resonance. I have a hard floor and use steel spikes sitting in brass cups - but I use electrostatics and so there are minimal cabimet resonance issues.

Both of the other postings are solid advice. I use Simply Physics feet under my electrostatics, and the spikes they employ are of stainless steel. The advantage of Simply Physics feet is that they are adjustable to within a few thousands of an inch, so if you have tall speakers and/or a less than level floor, you can still get perfect alignment in your placement (and imaging). I also use the Walker Audio Valid Points and the lead filled brass disks they press into. These are under my amps, preamp, and power supply. Sound Anchor has a new cup for spikes that protect the floor, I have a set, but have not tested them yet. Just as a note, I have never had good results with anything except spikes under any speaker. However, there are a lot of choices out there. It would be nice if you had friends that had some alternate products you could try for a couple of days to see what they do. That way you could hear the difference yourself. Maybe there is an audio group in your city that you could benefit from. My audio group is constantly helping each other with sharing and trying things.
