Why will no other turntable beat the EMT 927?

@brunorivademar  : " 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  "

Wrong again. What you posted in that thread specified: 0% speed stability and was you who posted on those 3 DD TTs you mentioned there and that I shared here.

@brunorivademar  : " 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.."

In this thread are posted the 927 specs. Look for and you will read how bad measures that EMT.

Dear @mijostyn  : I agree almost on what you posted but that BS expression because some vintage TTs, evenm today, have excellent design merits that we can't just dimished.

@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.

@mijostyn 

A turntable does not have timing or pace for that matter. 

Actually it does. Because as you said

A turntable just spins at 33.33 rpm as quietly and accurately as possible. A great turntable has no sound of it's own. 

But they don't. And there's the rub. Thats why they all sound different.

Instability in TT's will destroy the timing as recorded.
