Right. And it needs to be tuned according to both the frequency and amplitude of the vibration you’re trying to filter out, as well as the mass and fundamental resonance of the device you’re using.

That's why I say I got lucky. Without any special knowledge, out of abject desperation, I built this suspended platform. I realized just how lucky after I tried to replicate it in a different form. Footfall problems even got magnified in one attempt. Lost clarity. Once right, the platform actual will slightly swing or sway after I place record and stylus. One thing that still stuns me is how sound stage size added a quarter in size above the one I had grown accustomed to before. And I do mean, above, that is, audibly higher in the room. AND, the whole is less tube like and natural. I think my Sunfire sub HRS-10 was really blurring everything. |
Clever and effective. The best frequency is between 2 and 3 Hz. You can tune it by adding mass. If you get it right you should be able to jump up and down indiscriminately. The improvement in sound is also no surprise. If you get a SOTA , SME or Basis you can put the turntable anywhere on anything and it will do just fine. IMHO an isolated turntable is a must. |
As for mass...a 2 pound record weight rides along to keep things solid. Deer skin platter mat. Cambridge Audio phono pre amp. The analog fever on the cheap. Leveling is perfect due to easily adjustable toggles on mid weight bungees through posts. =Found out the hard way, the bungees must not touch plinth. Added Iso feet under free standing frame. |
