Turn table speed variation question


I've always found that tracks containing sustained piano notes (chords mainly) seem to highlight the smallest variation in platter speed.

However, I do not notice the same speed variations with sustained notes played on any other instruments.

Works well when auditioning turntables, but a PITA when you hit those older, less than stellar recordings, where the tape machine cause the issue.

Wondered if anyone else had the same experience with a different instrument, or is this specific to the piano.

Thanks

Perhaps you would like to make a video of your TW Akustics and add it to the database.
Heh heh......unfortunately the Raven AC-2 or AC-3 is unable to be adjusted to the exact 33.33rpm with its motor controller.
Some would say this is maddening oversight?
It does however seem to maintain a uniform 'loss' of speed...if that makes any sense?
I applaud you on your SME results and your attempts to encourage others to do the same.......however I somehow doubt that many will contribute as it is just so difficult for a turntable to achieve this feat under constant stylus drag....and no-one wants to have his turntable 'publicly' exposed?
Just for the 'record'....hehe....and to comply with Peterayer's request......
HERE is a video of the TT-101 playing a record (single arm and cartridge).
At the beginning and the end....where there is silence.....the arm has not been dropped...or has been raised.
Halcro, thanks for posting that new video. Love the music and the results are
most impressive.

I agree with Dover that once a certain level of speed accuracy is achieved, other
issues become much more relevant. Speed CONSISTENCY, or what happens
between TimeLine flashes, is one, as are the others mentioned above.

I've just added a video of my old DD Denon DP-45F on my WBF thread database
and results are poor. I'll shortly add a video of my friend's Technics SP10 MK2a.
The Denon is not a particularly good turntable, but it was fun to bring it out of
storage and have a listen. It spun lots of Led Zep back in my college days.
Just added the video of the Technics SP10 MK2a. The results are as impressive as with Halcro's Victor. Here is a link:

Thanks Peterayer....and thanks also for the Video of the SP10Mk2A.
It is indeed a fine result with the Timeline.
As steady as the TT-101.....
I couldn't connect with your Link to the Denon?
Any chance of posting it here?
