A Copernican View of the Turntable System

Dgob, any resonance in the arm tower will be a coloration. If the feet prevent the tower from coupling to the base of the platter bearing, that too will be a coloration.

How cool is this thread??

Lewm,

Yes. I'm using this as an exercise in decoupling and I've now gone back to using a combination of viscoelastic sheeting, blue tac and spikes under the arm column. Early days but so far, so good...

Atmasphere,

Thanks again. The funny thing is that the spikes do not offer the level of rigidity that I need. They do however offer grounding. The mix of methods that I am currently using is producing very interesting results but I still need time to explore the accuracy and pros and cons of this (decoupling) approach.

I'll give ffedback once I'm certain.

Atmasphere,

PS: I still hold some interest in trying the metal sandwich platter. So if you fancy pulling your finger out about designing one (that I could import to England), do give me a shout off-line;~) SAEC just wont work, financially at present!
