Then, you need to isolate the platform from the myriad vibrations coming up through the floor, walls etc due to footfalls,washing machines, passing pedestrians and road traffic, etc, etc. The only way to isolate is with a proper spring system, calibrated for the weight of the deck and the platform. Spikes, string, sorbothane, gel stuff do not provide isolation down to the levels that matter with what Roy Gandy calls a vibration measurement instrument, eg the record player. Springs may seem an easy matter; indeed the maths is easy enough, but creating spring supports with optimum stability and sensibly applied damping is something else.
You could go round in circles for years trying to avoid buying something that works straight out of the box to satisfy the criteria outlined above, but Townshend's Seismic Platforms do work, and in the case of turntables, magnificently so. They provide near full isolation, with good inherent stability, in a very slimline and discrete package. No, they are not cheap, but My Goodness they work; and Townshend will change the pods to a different load rating if a customer needs something different down the line! Not a single person who has tried my demonstration Seismic Platform has declined to buy one.
