A Copernican View of the Turntable System

Dear Dgob: I assume that in both tonearm quality performance is first rate as you posted, thank's.

Very nice review Dgob – kinda makes use wish you had your sp10 back Banquo ?

I have been using the AT-616’s for a couple of weeks. I was able to make my ET 2.5 arm fit by raising it to its highest point and using higher spikes.

The 616’s adjustability makes leveling of the sp10 platter very easy. For those familiar with the ET 2.5 ensuring the air bearing arm is level is even easier – laser guided or regular level not required.

I still believe the key to the improvement was and this is gut feel only 75% isolated armboard and 25% getting the sp10 out of its plinth. Isolating and mass loading the armboard I feel was key.

Dear Dgob – you listened to your setup with the armboard attached to the naked sp10 first – it improved the sound sure – but wasn’t the bigger jump in quality getting the armboard isolated and mass loaded ?

Any thoughts on this.

Cheers Chris

Dear Ct0517: I think that you could be right about that " isolated " subject. As you I can't be sure.

I have the same gut feel.
The isolated and heavy arm boards I believe, are a revelation.

Chris,

Sorry but just a quick follow up. Did you try the arm tower on your fourth AT616 and, if so, what was the outcome?

Thanks
