All the comments remind me of the endless discussion of speaker drivers and the material science that relates to it. As many have suggested, whatever sounds best to you, is the best. That goes for all the links in the chain. In the meantime, the cat will keep chasing its tail.
Direct drive/rim drive/idler drive vs. belt drive?
O.K. here is one for all the physics majors and engineers.
Does a high mass platter being belt driven offer the same steady inertia/speed as a direct drive or idler drive?
Is the lack of torque in the belt drive motor compensated for by the high mass platter. Object in motion stays in motion etc. Or are there other factors to take into consideration?
I am considering building up a Garrard 301 or Technics SP10, but is it all nonsense about the advantage of torque.
I am aware that the plinths on these tables can make a huge difference, I've got that covered.
My other options would be SME20 or Basis 2500 of Kuzma Stogi Reference etc.
If I have misstated some technical word, please avert your eyes. I don't want a lecture on semantics, I think everyone knows what I mean.
Thanks in advance.

08-02-09: AxelwahlFor a long time the SMEs were the only belt drives I'd heard that don't mute transients and artificially "relax" the musc. Fortunately, now the Ayre/DPS turntable creates the same sensation for significantly less money. I'm not saying it's as "good" as a $30K SME, but if that's the sound you like and can't spring for a SME, look into the Ayre. |
How long is the initial transient of a piano note, a string pluck, a drum or cymbal hit? I suspect the initial dynamic jump is well under 1 ms. How large, physically on average, is such a transient "bump" in a record groove that is 1400' long for a 20-minute side? If belt drive flex lengthened that transient by 10-20%, it seems to me we would be talking about parts per million from one standpoint, but possibly a quite audible 15% variation from another. |
Johnny B You don't seem to understand the function of a low pass filter. It is not possible for the belt drive flex per se to affect anything by more than a few parts per million for the reasons given. A change in belt tension will however create belt creep and this effect will be around 1000 times larger. That was my point. Mark Kelly |
