Direct drive vs belt vs rim vs idler arm


Is one TT type inherently better than another? I see the rim drive VPI praised in the forum as well as the old idler arm. I've only experienced a direct drive Denon and a belt driven VPI Classic.

Dover,Ct0517 IMO the timeline is really only good for testing long term speed stability at least the old one was....the Kab strobodisk will and can tell you more on the short term this is what i used in the video...no other turntable that i have used or played with could correct so fast that our/my naked eye cannot see!

for all and anyone interested in what that tt was please contact me offline as i do not want to cause a rukus and or panic..

Hello Dover i just want to clarify that the turntable is not hunting correcting etc.. the reason you see the 33rpm marker moving is because i am putting lateral force(on the side of the platter) it is dead rock solid :)

Hi Richardkrebs/Peterayer, for the record that is Lawrence's video (Lharasim). Not mine. All I did was put it into a direct link on the thread for viewing.

As in my earlier post on 12-30-12 belt creep is inversely proportional to the elastic modulus of the belt.

Creep = T/r x A/E where E = elastic modulus .... Mark Kelly

if a belt is inelastic, then E = infinity, and the creep is infinitesimally small.
Halcro, thanks for making and posting your video. I just viewed it and have a question I don't believe anyone else ask as yet.

I'm not familiar with the Timeline, never having seen one in person. In your video there appears to be an initial flash on the wall above your FR arm, prior to your BluTak marker. Is that a reflection? I understood only a single flash was produced per revolution.

Thanks.
