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.

Halcro, nice job with the timeline video. I doubt it will shout up the audio Nazis but who cares. Anyone with a brain can see past the internet bully thing.

Certainly any one overstating what the Timeline "proves" discredits themselves.

Tony, your input to the speed stability threads has been very helpful. Its a nice contrast to some of the pseudoscience b/s that some throw around in this forum.
Lew, the Kuzma was (or is) too fast anyway, be it with needle in the groove or not...and Halcro, well he is a guy who ignores everything he does not want to hear and when you read 2 sentences from him which makes sense, you can bet your car he got it from former member Dertonarm. and this "I don't like Raven nonsense..."...not my problem when he (and others from the Fanboy section) is not able to analyze the own stuff properly. And his Seiki nonsense, compared to that is any Raven a time jump back to stone age...
Wouldn't it be a better idea to spend $400 for a Timeline, and choose a turntable which passes the speed test or is it better to keep the own mediocre unit because it can't be sold properly?
I would buy a better table, but this is of course my opinion :-)

Tony, According to others, the laser flashes 6 times per revolution. That means you can get a read-out every 0.3 seconds. So you are indeed "averaging" the speed, but it is over a very small increment of time....

Another example, the new Airforce One Turntable from TechDas has 1x contact per revolution with the own motor controller. This seems to be enough to hold the platter speed no matter what is going on. I never checked it but I read from an owner who did the Sutherline Test and it was ok. Personally I believe it because when the Japanese do something serious, they don't make a fault like this.
When timeline has 6 flashes per revolution, it isn't that bad, or?
I am not a fan of servo controlled speed. The speed is wrong a lot of the time!

A properly designed turntable should run at a constant speed!

If there is stylus drag (that audibly effects sonics) , then increase the speed slightly.

I like the VPI SDS - regenerated AC - a variable Quartz crystal controlled frequency in steps of 0.01 Hz - after startup reduces voltage for lower noise - modified sine wave for smoother motor rotation.

It made a "huge" sonic difference on my TNT III, when the speed was set with strobe disc.

All the VPI Classic turntables need the SDS, even though it was originally made for the TNT line.

wow, you are not critical of the AF1 ? As far as speed control, it helps when you use a built in tachometer that monitors and speed adjusts based on record drag. Record drag can vary record to record as I am sure you know...
