A Copernican View of the Turntable System

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?

Dear Henry, We agree on something! That's exactly what I was trying to imply to Dgob without being annoying.

Halcro,

I have experimented with weights on the arm columns and with vtf variations. So far, not adequate. However, the fun continues...

Atmasphere, do take my suggestion seriously.

Lewm,

I don't think there was anything annoying about your opinion. Honestly! The key issue here is one of decoupling and if you review this thread you should see why the experimentation.

Hi Henry- you stated and I agree with this concept based on what I am hearing so far.
"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."

Both my sp10 and ET armboard are on spikes. However.

I am also thinking if you are able to isolate the Platter/motor and armboard "properly" then this should not matter "as much" ?
If someones specific combination works in their system/kit it should be evident in what you hear - which is what matters not the concept.

This project has provided me with very neutral,distortion free sound - meaning to me no pronounced highs or lows, followed by what I have found to be a very strong desire to... and be able to - turn up the db as Dgob stated in an earlier post and enjoy the music immensely. Isn't this last sentence the PROOF "for me anyway" if certain projects are heading oneself closer toward "shangri la" in this hobby ?

My listening since implementation has been at a higher db. I'd like to go higher still but my family doesnt allow it. I need to spend more $$ first isolating my sound rooom better :).

Curiosity killed the cat - I put a wanted ad out for those AT616's and someone from Denmark replied and well I now have a set coming to me to try out this theory different feet on TT and armpod/board. I want to hear how it changes things up. Will let u know.

Hi Dgob

How heavy is the Acoustic Signature arm board that you are using and I am curious what type of center clamp you are using on your sp10 ?

My ET 2.5 armboard weighs more than the sp10 itself.

The next one will be made of brass and I will ensure it weighs more still. I feel the weight on the spikes is critical for isolation.

Dear Thuchan - thank you very much for your cartridge recommendations for my ET 2.5 arm.

Cheers Chris
