Why will no other turntable beat the EMT 927?

And yet the TD124, when compared to even the top level of pedestrian idler drives, like the Garrard 301 and the Lenco L75, comes in third in terms of sonics. to my ears in my system.  Moreover, I have liked many other belt-drive and DD turntables over the TD124, as well. So, either your numbers are questionable, or speed stability is not the paramount determinant of SQ, or we just hear differently. (This says nothing about the EMT 927, which I have not heard.)

Vintage turntables did have heavy platters, vacuum suction, air or magnetic bearings, and high torque motors, although no single one of them had all those supposed virtues (all of which come with some trade-offs.)

Well said, @lewm .

Dear @brunorivademar  : Speed stability is only one TT characteristic for a good quality performance but exist other parameters that have in between an intrinsecal realtionship.

You took an untrust information as one of your premises for your statements because in this Agon Analog forum the M.Fremer measurements are not what we all imagine. It's not a trust tool as he showed in the reviews and at the end in that discusiion where he participated he told us that he did those measurements " just for fun " and nothing more.

This is what MF posted:

" I am careful to state that these Platterspeed measurements are for “entertainment purposes only”. All test records are faulty as are all records to one degree or another...""

in that same thread you posted:

With regards to speed stability only 3 tables I believe take the crown.

Yes, speed stability is critical in any TT.

@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
