Turntable speed accuracy

Davide 256, 'the average stylus pressure is 1.5 gm.,etc.' I was always wondering about this 'drag issue' more in particular because of the 'vulnerable' stylus cantilever combo. But as a non-technical guy I was not brave enough to say something although I asked the question how this 'vulnerable thing' can cause such problems? Well I was dismissed but not convinced. I still have this 'picture' of an elephant (the platter) and the mouse (the stylus) in my mind. BTW 'my elephant' is 8 kgr.

Regards,

Davide256: "Direct drives are very difficult to isolate (vibration) vs belt drives"

Really? What if there is little or close to no vibration in direct-drives to isolate to begin with? Not sure you understand how direct-drive system works...

stylus drag is not that much depending on VTF .....

Davide256, everything you write is so obvious and logical, yet wrong as regards points one and two. Point 3 does count for a lot too, I grant you.

People who don't like direct drive generally make the same point you have made re "isolation". Usually such persons do not own and have not owned a direct drive turntable. However, if you examine the workings of the best examples, you will see that the platter is part of the motor. Thus "isolation" is really a function of the quality of the bearing, which is an issue of equal significance for BD turntables as well.

A friend of mine has progressed through a series of decent tts over the past few years. He started by adding a Teres rim drive to his VPI Scout (big difference, even greater than the VPI rim drive), then through a series of DD tables from Technics, Kenwood, and Luxman. More recently he got a Micro Seiki belt drive (not sure of the model but it was not the low end). Speed was not accurate and the MS motor could not be adjusted/repaired to run the proper speed.

On an inspiration he adapted the Teres more with a proper sized pulley (and reversed the rotation direction) to drive the heavy MS platter via a string drive. This is a person who has decades of experience in this hobby and he believes he now has the best tt set up he ever owned. I have not heard every iteration he experimented with but will say with everything from a full symphony crescendo to a sustained piano chord it provides beautiful and believable playback.
