Why do turntables sound different?


Let's consider higher-end tables that all sound excellent. Same arm/cartridge and the rest of the chain. Turntable is a seemingly simple device but apparently not quite or not at all.
What do members of the 'scientific community' think?

Would love to hear the differences on the above 3 turntables you liked.  You have direct drive and a heavy platter with 3 motors and lighter platter with 1 papst motor.

I would like to hear about the tone, body, decay, attack, pitch, and separation of instruments.
I'm not sure I would characterize it quite that way...

Its important to understand that I've not heard all these side by side. At least all the 'tables mentioned had the same arm installed- the 12" Triplanar.

The best so far has been the Technics SP-10 MkIII. It came the closest to tape in the regard that there was absolutely no shimmer in the sound stage- something that is hard to describe until you hear it.

The SL-1200GAE was really similar. I've not heard it with the stock arm.

The model 208 is next- it is less speed stable, but does have a good solid plinth that is pretty dead and a very dead platter. The Kuzma was very similar but its plinth is not as dead. In addition if I had to guess I would say its drive simply is not as robust- it takes longer to get up to speed and the speed drifts more with stylus drag (but to be clear, not by much at all- its an excellent machine).

We've had tape in our room at shows. I've heard the 'tables above outperform the tape on the same titles; since some of those were analog sources, its led me to believe that we are in a period where lots of titles are showing up on half track 15ips 10.5" reels that don't have the provenance they need to actually outperform the LP- IOW, the LP is significantly closer to the master than the tape.
You guys run and sell your Comtinuums, Walkers, TechDases, Kronoses etc. real quick. They are not as good as Technics. And don’t argue, just do while you can still get a good price. Yeah, Rockport too.
I am not talking about 100th generation copy of the master on junk tape. There are much more advantages than soundstage. But it should be top deck in top condition.
I'll take the new Continuum Obsidian, you know, the one with the mag lev isolated platter with huge, and I mean huge bearing. Also vibration isolation system for the tonearm. You guys can fight over the rest of them. And I would definitely use the Audio Technica wet playing system.
