Turntable speed accuracy

Halcro - great demo, no accent.

I agree with Lewm on neutrality, different for different folks. We all know if we have a preamp with a dip at 3k say and we listen to it for a long enough, the ear/brain adjusts, and when you try something else that is neutral you think it has a peak at 3k.
I would suggest that speed and timing are far more important, as once you have lost the timing you cant recreate it in your head.
Re Wave Kinteics NVS that started this thread - did anyone notice that that original thread has disappeared. Do manufacturers get bad press/comments pulled from the forum ??

Ha Ha Ha - yes sure dialect. Its wonderful either way Henry :^)
And music is the common language here.

ACCENT vs DIALECT

NEUTRALITY vs COLORATIONS

What a great hobby

Dear Halcro: I could listen to you reading the phone book and find it gripping. You speak with a deliberateness and cadence of several philosophy professors I know. Put differently, you're the John Gielgud of the audio world.

More videos!

Dear Thuchan: I think you have a wrong concept of neutrality/accuracy on audio devices.

IMHO any audio device should let pass the LP/cartridge signal " untouched " and this means with accuracy/neutrality: IF THINGS ARE THAT THE THE TRACKS ON THAT LP ARE WARM/COLD/LIVELY/DYNAMICS/BRIGHT/DULL/DARK/ AND THE LIKE WHAT SUPPOSE THAT ANY AUDIO DEVICE/AUDIO LINK IN THE WHOLE AUDIO SYSTEM CHAIN MUST DO IS TO PASS ALL THOSE LP MUSIC RECORDED CHARACTERISTICS WITH NO ADDED DISTORTIONS/COLORATIONS BUT WITH ACCURACY/NEUTRALITY.

ALL THOSE MUSIC RECORDED CHARACTERISTICS came/comes in the LP and in theory are not part or be/bee need development by the audio links: what you hear must be what is in the recording: adding NOTHING!!!!! or do you think that your system is so good that can improve what comes in the recording?, no way my friend no system can do it!

Do you think that all those additional " stuff " in your Micro Seiki improves the sound?, NO only change and add different distortions with no real improvement.

Regards and enjoy the music,

Tony, What I meant was that in direct-drive turntables, the motor, the drive system (aka servo), and the platter together form a closed system. So indeed the mass of the platter has everything to do with it. If you don't see what I mean, try removing the platter from a direct-drive turntable. The result will be a pronounced herky-jerky motion as the servo goes searching for its proper load. If you dramatically increase the mass of the platter (yes, "m"), the servo can get similarly screwy, slow to correct for off-speed moments, but it is less easy to see. It is the servo that tells the motor "how much acceleration is enough" to get back to equilibrium.

None of this is to contradict what you say about LPs with off-center holes (i.e., most of them). That's a big, important, and separate issue.
