Why will no other turntable beat the EMT 927?

@rauliruegas "

Techdas Airforce Zero speed inaccuracy -0.34% + 0.45%

0.79% speed inaccuracy

Oma k3 +-0.34% 0.68% innacuracy.

Much worse results.

Got it?

Can you see the measurements right in from of your eyes?

This are the true facts, not illusions

@dover You said the weakness of the 124 is the belt. I agree. In fact I was just wondering if I could build some kind of kevlar belt for it. Something more stable. Belts are definitely a problem.

Also interesting point you mentioned regarding the self correction of AC motors vs DC motors. 

@rauliruegas I've read Fremer's reviews. I can't speak for measurements using a vinyl disc but I do believe gyroscopes give pretty accurate readings and I stand by what I said.

The 3 turntables I mentioned are all direct drive but they use some kind of wizardy technology that I don't understant. They are the exception. And that's why they are the only ones to have those numbers published.

Hi @thuchan .

Do you happen to have a speed deviation measurement device like a shaknspin?

I believe the magic number lies in the speed deviation %. That which Idlers rule above other drives with their high revving motors. Yes DD drives are also high torque and so can overcome stylus drag but they fail at that measurement also.

Not only is the 927 an idler drive (the best idler drive) but it also happens to have a 16" platter which gives it even more superior stability.

I may be wrong but I believe i’m answering the question you presented in this thread.

Think about it. Modern turntables of today come with tighter bearing tolerances. Much heavier platters. Vacuum suction. Air bearings. Magnetic bearings. High torque motors etc etc. Yet all fail at that test. Take a look at the measurements of all the last uber decks including Airforce Zero, Oma K3 and SAT in stereophile. Constant speed deviations of 0.25% / 0.30% / 0.35%. 

I would bet your 927 is going to show you a deviation of 1/10th of those numbers. My humble TD 124 shows me 0.04%. Timing is everything!

@lewm Hi, keep in mind i’m only speaking in terms of measurements, not at all claiming my Thorens is better sounding or anything. I’m also well aware that the Garrards and Lencos are considered superior to the 124. All i’m saying is that with regards to that particular measurement idlers seem to have an advantage because of higher revving motors and thus less motor cogging. I would challenge any direct drive or belt drive turntable owner to share speed deviations and not many would be below +-0.20% Does it make any difference? I have no clue.

@rauliruegas I can assure you the gyroscope inside the Shaknspin Fremmer has been using for his reviews is pretty accurate. I believe he is being cautious because the numbers don’t look pretty.

Speed stability is not the only factor to sound quality, there are other important things too, we can all agree on that. But the only thing I can think the 927 has in favor besides the high torque is the much lower deviation from a perfect 33.33 at ALL times. We are talking micro second to microsecond timing. The bearings are nothing special. No vacuum hold down, exotic materials, airbearings. Nothing! :p

@mijostyn Idler drives don’t rumble if you know how to make a few modifications. Btw did I ever say antique turntables are superior? Don’t put words in my mouth. Anyway you are being too passive agressive and I have no interest in engaging with you. Go get your self a cup of tea.
