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, I agree the test record has an eccentric hole, as do most music records, so the variation in speed from the effects of warps or eccentricity is there on all records to some degree, do you think this makes a mockery of perfect rotational speed? Perhaps Nakamichi was onto something with their record centring mechanism. I have posted screen shots of the Feickert test on the TS 700 with and without centring, and it makes a considerable difference! I suspect the variations detected by the test tone +- 2 Hz at 3150Hz, would be undetectable with the time line. Did Nakamichi make the "best" TT of all time?:)
Dover, My apologies. I probably sounded more indignant than I actually am or was. Perhaps lifting the paragraphs word for word (I knew they sounded familiar) with no attribution is not.... something. But this is the internet, all junk food all the time.
Dover,
yet you have not posted a single video of your 'famous' Final Parthenon performing with the Timeline in any fashion whatsoever?
You really need to work on your comprehension skills.
Your 'speed reading' abilities are flawed.....
Again you ignore the vital word....TIMELINE....?
Halcro - Did you miss the knuckle test I posted.
No...I got that one.
It's about as useful as demonstrating a turntable being able to perform under water?
It demonstrates a serious lack of appreciation for the actual forces involved on the stylus due to groove modulation and friction which are responsible for 'stylus drag'.

But FYI....the TT-101 passes this nebulous knuckletest.....not for the three paltry seconds on your video....but for the full 3 minutes with the TIMELINE....not the inaccurate strobe which you continue to use.
Dinster,
I have a good friend who owned a mint Nakamichi TX-1000 among his EMT927, Micro SX-5000 and SX-8000 as well as Continuum Criterion collection.
After a year or two....he became disillusioned with the sound of the TX-1000 in comparison to his other decks and sold it.
Centring the hole of the Lp does not guarantee consistent speed control of a particular turntable?
It simply removes one possible cause of distortion when playing an eccentric record on a turntable WITH perfect speed consistency.....
Lewm, thanks for your kind words. I agree there is a lot of "junk food" on the net.
