stylus drag is not that much depending on VTF .....
Turntable speed accuracy
There is another thread (about the NVS table) which has a subordinate discussion about turntable speed accuracy and different methods of checking. Some suggest using the Timeline laser, others use a strobe disk.
I assume everyone agrees that speed accuracy is of utmost importance. What is the best way to verify results? What is the most speed-accurate drive method? And is speed accuracy really the most important consideration for proper turntable design or are there some compromises with certain drive types that make others still viable?

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. |
Speed Accuracy done right at Monterrey / California via thread Drive. We have a small black hole in the wall, right behind the turntable. We guess it is a Laser burned one :-) The Return of The Jedi 5....Kings at work |
Dear Syntax: Well Halcro has a wider black hole in the wall, right behind the TT. This TT is a DD 400.00 Victor TT. So not big deal what you are showing against the humble Victor or my Denon one. It is not here at speed accuracy/stability where belongs the " secret " for a top quality level that you till today can't even imagine could exist. Have fun. Regards and enjoy the music, R. |
