3 New UBER Decks - Is this Turntable's SwanSong? 🦢

Michael Fremer has recently reviewed three new turntables designed to be the 'Last Word', 'Cost no Object' STATEMENTS!!!!........Do I recall hearing this claim before??
I love Mikey and have followed (and trusted) him for decades.
He has been the longest and foremost published 'champion' of the superiority of vinyl (uber alles) in the world.
I am thus ecstatic that he has been able to listen and compare these decks in his own room, with his own equipment virtually side-by-side
It's almost a 'given' that he will be the ONLY person on earth given that privilege....

So what Mikey HEARS.....is indisputable

Given his 'character' and desire for accuracy and honesty.....years ago, Mikey started including some 'objective' measurements in his turntable reviews.
These measurements were done utilising the Dr Feikert PlatterSpeed App which has since been discontinued.
As the App only worked with the Mac iOS of many variations ago.....Mikey has kept an old iPhone which can still operate the App.
The PlatterSpeed App had a few technical limitations.....
Foremost amongst these, was its dependence on a 7" record with an embedded 3150 Hz Frequency track to produce a test-tone which the App could process through its algorithm to produce the graphs and all the corresponding numbers.
To stamp hundreds of 7" discs with perfectly 'centred' HOLES is a nigh impossibility.
It's almost impossible to do it with a 12" disc!!!

This means that ALL the figures produced in their Chart Info are dubious and mostly UNREPEATABLE!!!!
I have Chart Infos for the same turntable/arm combination but with the 7" disc moved slightly producing different figures.
I even have Chart Infos produced with the same turntable but different arms ALL with different figures (the arms are in different positions surrounding my TURNTABLE).

So what is my point......?
The GRAPH produced with the PlatterSpeed App is accurate and USEABLE when looking at the 'Green' Lowpass-Filtered Frequency.
If the hole was PERFECTLY centred.....this 'Green' line would be perfectly STRAIGHT......but only if the turntable was maintaining its speed PERFECTLY.
The wobbles in the 'Green' line are due to the hole's eccentricity as well as any speed aberrations.
So the best performing turntables are those with the most constant and even wobbles approaching as closely as possible a STRAIGHT LINE.

Now the SAT Direct Drive Motor is actually the same as Technics developed for their latest SL-1000R except with some bespoke modifications.
It appears that SAT have corrupted what is a very good DD Motor unit....🥴

Mikey says that the OMA-K3 produced the best PlatterApp figures of any turntable he has tested đź‘Ź
Does this mean that the OMA-K3 is the most accurate turntable of these three decks.....or maybe of ALL turntables?

Mikey can't (and won't) test and review products from the past which are no longer produced because that's not his job!
But wouldn't it be great if someone WOULD review products from the past against the modern equivalent?
Classic turntables with reputations....gravitas...like the legendary EMT 927 and Micro Seiki SX-5000 and SX-8000.
And what about the NOW lauded Japanese DD Turntables from the '80s...the 'Golden Age' of Analogue?
  • Technics SP-10Mk3
  • Kenwood L-07D
  • Pioneer P3
  • Victor TT-101
  • Yamaha GT-2000
Because we know that Direct Drive is now 'Flavour of the Month' for the new Uber Decks due to their superior speed accuracy....a 'Flavour' that started with the legendary Rockport Sirius III.
But what about Belt-Drive units like my 20 year-old Raven?
So much for science and technology.......

We can do things today that were only dreamt of even 10 years ago
Except learn from history, harvest experience, expertise and craftsmanship......

Here endeth the Sermon for today 🤗

Dear friends : @dover  said: "   what you want is stability..." and he is totally rigth because the most important characteristic in a TT is speed stability.

Btw, that his Final TT " slaughtered " all those DD TTs is just his opinion. It's like talk with a tube lover about SS electronics, obviously that for him tubes " slaughtered " SS alternative.

He said too:  ""  My gut feel with historical top end DD's is that error correction servos, like digital, are doing the damage. ""

Obviously that's a " feeling " and here we have to remember that all the record cutting machines motors ( Technics between them ) used servo control. So if this servo correction is the problem why is not " reflected " in our LPs during play. 
I own and owned DD/BD and I can remember to identify that  "  DD's sound thin ...."
I think that's all about the whole room/system performance and not because the DD servo. servo.

Also, to the argument about servo devices and their effect on sound quality, most upper end belt drive turntables these days employ some sort of mechanism that senses platter speed and feeds back to the motor for speed correction. Why is this harmless with belt drive turntables and yet an Achilles’ heel for direct drive turntables? Of course, I do not know whether Dover’s turntable uses such a speed correction device.

Because the belt acts as a filter of sorts and the bearing is free of an integrated motor.

@freediver who was the Linn dealer in Larkspur Landing in 1981?  Access To Music moved there from Mill Valley around 1993 or so.

OMA states on their Website:-
The design of K3's mechanicals is the work of a team led by Richard Krebs in New Zealand, the world's foremost authority on direct drive turntable technology.
Perhaps a Footnote is needed:-
Assuming all the Engineers at Technics, Victor, Pioneer, Yamaha, Kenwood et al are now deceased?


This is a good point. Personally I never heard about any Krebs product, except for his modification of Technics SP-10mkII motor on this forum. Is there anything else Richard Krebs actually made?
