A Copernican View of the Turntable System


Once again this site rejects my long posting so I need to post it via this link to my 'Systems' page

Halcro,

Thanks for the kind words. Regarding the plinths tried, I tried a birch, aluminium and acrylic composite plinth. I also tried various directly coupled arm boards. These included ones made of birch/aluminium, ash and MDF.

Of the armboards, the ash was the best performer (in view of the achievements and criteria that I have used for the nude approach). The bespoke plinth is of my and my artisan brother-in-law's design. It performed well but the experiment with the nude and stand-alone approach has meant that we're back to the drawing board and trying to see if we can incorporate some of the apparent lessons into a new design.

This is only an exercise to see what is really possible (plinth wise) for those who MUST have a more traditional arrangement. However, given financial and time constraints at present, it might be quite some time before any advances are made on this front. When they are and assuming that the results are worth noting, I'll definitely feed back.

In truth and thanks largely to your and Raul's initial suggestions, the nude and stand alone approach are (as I've sought to explain) all that I could wish to achieve.
Halcro,

Sorry, I should have also said that I have also based my comments on the nude approach in the light of my experience with the various other TT's that I have owned, which I have referenced before.
Dear Dgob: Which tonearms do you already try/test on the naked TT?

Regards and enjoy the music,
Raul.
Dgob, You might try a laser-type device for assuring that the table and arm mount are plane parallel. I believe such things are now commercially available. I would not completely trust a small spirit level; a large long carpenter's level would be better. That's what I use to make sure that platters and plinths are perpendicular to the force of gravity and parallel to each other.
