Turnable database with TimeLine

I verbally reported some results I got with my SP10 Mk3, using a Timeline borrowed from my neighbor up the street. (Yes, there are two audio nut jobs living on ONE short block in Bethesda, MD, USA. What are the odds of that?) He was using the Timeline to prove to himself and to me how very unstable was his very high end very expensive belt drive turntable, with a massive platter, I might add. The manufacturer told him there was a fault in his new motor controller to account for his disappointing observations. And now recently the new motor controller and a new kind of belt have been acquired. I don't know what these two upgrades (?) have done to improve his situation. The laser beam was riding around his room so fast I thought we were in a Disco night club.

I've mentioned this before; one problem with the Timeline is that it seems to have been designed for the narrowest of the 3 possible spindle diameters. I found it will not fit on the spindles of my Lenco or my Kenwood L07D (or perhaps it was the Denon DP80). Has anyone else had this issue? Following on the heels of Dertonearm's clever protractor, it would seem that Sutherland could solve this problem by incorporating interchangeable spindle holes, that could screw on to the bottom of the device. Thus, even more vinylphiles could be driven mad.

Ok.., what is the music this time?
Nice

I missed your report on the MK3 with the Timeline. Are you able to repeat them here?
Thanks

Nothing to say except it was bang on accurate, with the laser beam hitting a wall 8 feet away. I did not try a wide variety of music, and I did not persevere for very long once I felt the point was made. Perhaps in 10 minutes of observation there might have been some deviation; I can't say either way. I think I watched the blinking light for 2-3 minutes at most. Then I fell into a "deep sleep" and did whatever my wife told me to do for a week. Eventually, I snapped out of it.

If you're asking whether I can post a video, the answer is that I lacked such a capability at the time, not to mention that I had no such idea, either. I can probably re-borrow the Timeline if inquiring minds want to know.

The real question is are these very, very small speed changes AUDIBLE!

I seriously doubt it!

Tape recorders and cutting equipment does not have perfect speed in the first place.

Many audiophiles like to split hairs with theory that makes no difference in real life. This is just golden ear BS!

8 feet to the wall, that is a tough test.

I understand your skepticism, but would argue that these micro speed changes are indeed audible.
Sure we have tape machine speed instability along with eccentricity problems. That said, speed changes due to stylus drag, which is where this thread has kinda coalesced, are fundamentally different in nature. This because the music itself causes it. This results in a subtle smearing and bending of the notes. A general softening of the soundscape. The effect can be " nice " but it is not what was laid down on the record.
