Tweakers' Asylum

Beginning about 40 years ago I started DIY isolation tweaks.

I tried marble on racquetballs with and without slits. I tried granite the floor and on sand boxes. I tried commercial ac isolation pads. I made my own pads. I tried Sims isolation pucks. I tried multi-layer platforms from VPI including one I had made for my 200 pound Final Audio, solid copper tt. I tried Townsend, Vibraplane, and various other isolation bases, including a very special isolation platform from Goldmund under my Goldmund cd player. I tried steel points, aluminum points, tungsten carbide points, brass points, delgrin points. I tried maple bases, oak bases, granite bases, butcher block bases, the Nuaance bases, etc.

Many of these one could not duplicate DIY. Many you could. With one exception that I know of, you are merely choosing among resonant frequencies the benefits are quite component specific. I think that some will prefer high resonant frequency isolation devices and others low frequency devices. Some will limit themselves to DIY and others not.

All that I would advise is that there is no one best device.

The only device that I know of that has no resonant frequency is the very expensive Halcyonic active isolation device. I cannot afford more than the two I have, but I would never consider selling either.

Hi.

It sounds you've gone a long way in such tweakings.

I got no problem with vibration & acoustical issues even on 120dB SPL peak level testing sessons, considering my basement where my audio den located gets only 7ft ceiling clearance!!

My purpose of equipment lifting is to improve the sound - namely, transparency, razor sharp imaging & lifelike soundstaging - at low cost without need to feed costly vendors. Do I ask for too much ?

With marble/granite+tip-toes+rubber-leg holding my tube/SS power amps, which costs me very little money, I think I am getting close to the sonic ideal. It was sonically a mess before the treatment.

Some may find granite solution kills the liveinless of the music. Not in my situation. It is so live, so bouncy even with a 50-year vintage power amp of mine (only after my bigtime DIY upgrade of course) that the music engagement I now get beats my SS direct current power amp !!

PS: my LP turntable get the similar idea of treatment using some 100lb
concrete blocks platform. It works fly colours.

  It was quite effective.
  
  Try a sand box under the thickest granite you can get.
