A Copernican View of the Turntable System

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!

Dgob,
As Lew and Ralph intimate, I believe both turntable and arm pods should be 'coupled' in the same way ie all spikes.
I don't believe you should have spikes on the arm pods and pliable footers on the turntable OR vice versa.
Assuming you are conforming to this, I still have some doubts about the weight of the aluminium Acoustic Signature arm pod being 'effective' enough on spikes?
As Dertonarm and Atmasphere stated, the greater weight applied to the spikes the better?
Regardless of all this, it may be that the spikes on the arm pod is giving you a 'better' isolation/coupling and just requires you to become used to the better flow of information.
Perhaps a recalibration of the loadings on those familiar cartridges may help?
Good luck and please keep us informed of the experiments?
