Turnable database with TimeLine


Here is a database showing various turntables being tested for speed accuracy and speed consistency using the Sutherland TimeLine strobe device. Members are invited to add their own videos showing their turntables.

"The Beat [like every other direct-drive turntable] has only one moving part, the bearing." The ad copy is correct; however the inference that this quality is exclusive to the Beat is exaggerated, to say the least. But I really really like the Beat. I think it may be the best buy in high end turntables, if $24K is a "buy", but I can live without the hype.

I think I mentioned this above; the Denon DP80 and other models use a genuine 3-phase AC synch motor. But they also built in quartz-referenced servo control. The servo can be defeated on the front panel. It would be interesting to compare its performance with vs without the servo engaged, but you might fairly say that the platter is not massive enough to give the momentum needed for the a non-servo dd to perform really well, even with an AC synch motor.

But isn't the argument that a massive platter and no servo is superior to a lower inertia platter WITH servo just an analog of an old argument among belt-drive aficionados, where the two sides argue over massive platter/weak motor vs lighter platter/torque-y motor? The more things change, the more they stay the same. Massive platters tend to "spread out" any speed error over time. Those who like them say that this is good. Those who don't don't.

And now we have "Mag-drive", because the buying public have been taught for 30 years that direct-drive is a dirty word.

Regarding the eddy current brake as used in the Beat TT
Please quote the authority to substantiate your assertion that the Beat uses an eddy brake ?

Go to teresaudio.com and follow the link...micro precise speed technology.
The Certus motor.
As I said earlier, this is an elegant design.
You have incorrectly claimed that the Beat uses phase lag to pre load the motor.

The Beat appears to uses electromagnetic drag to "pre load" the motor. Moving the rotor back in phase relative to the rotating field.
The Certus does not preload the motor using phase lag as you incorrectly claimed in your post re the Beat TT.
The white paper you refer to confirms my comments that the motor is preloaded from additional drag provided by the eddy brake, not the phase lag as you have claimed.
Motivated from Peter I tried to make my first Video ever :-)
The first one I made in the evening, the Laser was seen very good but it was too dull overall, so I started a new one in daylight.The file is compressed from optical quality but I think it is ok. The Laser is seen in reality below 2 letters (the "CK") in the name Fruhbeck. I stopped after 2 minutes, I wanted to avoid the make the file too huge but the Laser was still below these 2 letters after 5 minutes. That's ok I think :-)
The most other turntables I checked with that unit were out of specs after 5 seconds

I thought this thread was to be a database of timeline checked turntables - not a guessing session.
So did I……..
There are many other Threads where you can proclaim the ‘superiority’ of your choice of turntable…….
Instead of the subjective, emotive and mostly unproven claims often made in those ‘Mine is Bigger than Yours’ contests……this Thread was begun purely to demonstrate objectively (via the Timeline)…..the actual performance of turntables ‘under load’.

Videos and comments/observations about those videos are most welcome.

We have heard continually over the years….the claims of ‘superiority’ for the heavy-mass belt-drive turntables like the Micro Seikis and Dover’s Final Parthenon and I have no reason to doubt these….
We know also that both Dover and Syntax have access to a Timeline and we have seen evidence of Syntax’s abilities with photography and computer up-loads…..so it puzzles me slightly that neither of these individuals appears brave enough to simply post his turntable's performances with the Timeline on this Thread?
