A Copernican View of the Turntable System

Dear Dertonarm,
No......Galileo didn't have a happy life with the Pope in Rome, but his book gave him immortality.
I saw you as the perfect candidate as Galileo in this case with your new turntable almost perfected?
And then with Raul's new tonearm, we will all only have to worry about which cartridges to play with? :-)
Cheers
Henry

DT, I was joking of course. This discourse was getting entirely too serious. For any one of us to elevate it to the level of the concepts brought forth by Copernicus or Galileo is ludicrous. Socrates, maybe....

Dear Henry, your remark above to Thuchan re the SX8000 is in contradistinction to your original theory in all its specifics, as is the SX8000 itself. The SX8000 and the lesser M-S tts in its family, all use massively heavy plinths and an iron grip (literally) between the tonearm mount/tonearm and the chassis. I agree with it. But "motor separated from plinth/platter" leaves us only with belt-drive turntables. I thought you were enjoying your Victor.

Dear Halcro, the turntable, arm and cartridge do form ONE mechanical system. Tonearm and cartridge do form another mechanic-dynamic system of their own. There are wanted and ( more common ...;-) ...) some unwanted side-effects and synergies when putting the two "systems" together to get a record player.
The "plinth" and the "platter" do contribute (or detract ...) much more to the "sound" then most designers and audiophiles believe.
A full force vector diagram of the complete tt w/tonearm and cartridge and spinning platter (and building resonance ...) will nicely illustrate the interactions.
Cheers,
D.
