I had a Symposium Ultra with Stillpoint Ultra's under my DÁgostino Stereo amp for quite a while. the Ultra platform used to be under my turntable, but my $100 granite platform and compression springs had superior results. the Ultra platform sounded nice and was better than the Dag amp sitting directly on the floor.
I then read about Auralex Gramma Amp or Loudspeaker Isolation Platform and @ $69 they were worth a try.
My expectations were low to be honest. The bass was tighter, vocals clearer as well as the mid range and top end more open. Overall a lot better than the much more expensive Ultra platform.
After living with this for the last 6 months, I decided to go back to the Ultra Platform. After 2 tracks I comparison the Symposium was less detailed and overall seemed a homogenised musical presentation.
My wife was helping me here and we put the amps back onto the Gamma and even my wife said the music was so much better sounding now. These $69 Auralex Gramma Amp or Loudspeaker Isolation Platform are going nowhere.
they might be cheap, but give the Auralex Gramma Amp or Loudspeaker Isolation Platform a try and you may save 1000's
