A Copernican View of the Turntable System

Interesting thoughts Dover....
Watch this VIDEO on the Doehmann Helix 1 turntable when Mark Doehmann (who was head designer at Continuum for the Caliburn and Criterion turntables and also the Cobra and Copperhead tonearms) comes in to explain it (past the halfway mark).
Apart from the other interesting design attributes.....the aluminium that you think is the platter.....is actually a 'shield' against Air-Borne Sound Transmission and the platter sits behind it....🤗
Mark knows his 'onions'......

Thanks Shane.....
Not only 'cool'....the Herzan is a real listening experience for vinyl lovers.

I dealt with Reid Whitney directly at Herzan in the States.
He really knows his stuff.
Tim Rather then handles the production and delivery.
I paid what I had to plus 'extra' for a special larger top-plate (I didn't want to run out of room if I needed to mount some other 12" arms in the future) plus FedEx Delivery......it took 3 days from the factory for me to have it 👍

This is definitely not a cheap option Shane....
Thuchan is about to trial a cheaper version in Germany from Accurion...
Will be interesting to hear his thoughts.....

I also got me TS-150 directly from Herzan dealing with Tim -- a very easy process. 

I have posted the interference readouts from my installation as part of my system description (https://systems.audiogon.com/systems/5707#&gid=1&pid=31)

You can see from the traces that in my room I get a lot more background seismic activity than Halcro does. This is a wall shelf installation so that may explain why the main activity is in the vertical dimension. The time base for the scan is 165mS so the frequency of the activity is 10-12 Hz or so -- it strikes me that as this is close to the resonant frequency of arm/cartridge combinations it may be that eliminating this may be one of the reasons the effect of these active platforms is so profound.You can also see that in my setup I get some motor noise transmitted into the stand which the TS-150 does a good job of removing. My TT (EAR DiscMaster) is designed to prevent this noise making it into the platter (via a decoupled tension bearing and the give in the toothed belt) but it should help to also not have noise build up in the stand itself

Anyway just wanted to add my voice to back up what @halcro says about the benefits of addressing the record player as a system and working from the ground up

Dohmann may know his onions, but that "shield" would seem to offer no more isolation than is seen with the typical Denon, Victor, Technics, etc, designs that also shield the platter by sinking it down low, nearly level with the surface of the plinth. It may be that for a belt-drive, such an elevated highly visible shield is needed to accommodate the need for the belt to circumscribe the platter proper.

The Herzan has been integrated in my system for 6 months now, and not only is it the final 'piece' of the jigsaw for the 'Copernican' puzzle.....but it singularly is the most significant contributor to the elimination of 'distortions' and the elevation of sound quality that I have experienced in 40 years of audio.

That is because it is effectively acting as the plinth. The arm is now rigidly coupled to the platter, which is as it should be.
