Best vintage DD turntables from the 70's and 80's?

What is the evidence that Micro-Seiki built the Onkyo, Yamaha, Kyocera, and "some" Luxman DD turntables? I don’t doubt it, but I am wondering about the source of the information. Does Vintage Knob, for example, endorse the idea? While we are at it, does the Kyocera DD, with which I am totally unfamiliar, play in this highest end league?

Based on my reading, personal experience, and many visits to Japan, my list of the best would include, in no particular order: Sony PSX9, Yamaha GT2000X, Technics SP10 Mk3, Kenwood L07D, Luxman PD441, Pioneer Exclusive P3, Denon DP100M and DN308, and I’d be willing to add the Onkyo PX100M on faith. What have I missed? Victor TT101/801, I guess. Honorable mention to Denon DP80/75 and a few Pioneer models below the P3. Anyone want to add to this "ultimate" list, without compromising too much?

Just checked Vintage Knob.  According to that authority, M-S did indeed build two turntables for Kyocera, and those are the only two Kyocera turntables deemed worthy of mention on VK.  However, they are both belt-driven and sport ceramic platters which some of us don't like.  Anyway, because they are belt-driven, Kyocera cannot make the list.

@lewm    in your personal list don't forget the Nakamichi TX1000, Nakamichi Dragon CT, Denon DP100M
Emt 950, 948 and 938 for example.

It’s a little more complicated than simply Micro made some of this brand or that brand’s tables/drives.
In fact some Micro drives were made by Victor albeit not the very
top models simply a matter of convience.

Its also known in the case of the GT-2000 that Victor’s speed control
engineer was brought in on the project don’t recall if the rest of
the drive was all Victor. There was the post by J. Carr way back and on a Japanese site.

So plenty of overlap all over the place more than we will ever
find documented.

I'm sure that is what we were told by the Luxman rep; that Teac manufactured the motors to Luxman's specifications. Having said that, I am not sure that it is true. For some reason the owners frowned upon sales folks disassembling expensive gear.

But it does make sense. The PD-441/444 motor does bear more than a passing resemblance to that used in the original Teac TN-400.

Serviced PD-441 this guy claimed the motor is made by Mitsubishi , here is the video. 
Before that several member of this forum claimed it could be made by Victor, Micro, or even by Teac. 

Lewm, I don't have any first hand evidence, but this is claimed on numerous forum discussions and websites, including vintageknob. I shouldn't have stated it as fact the way I did, but there is at least some circumstantial evidence. According to vintageknob the Nakamichi TX-1000 was also built by Micro to Nakamichi's specifications. As for 'some' Luxmans, the PD-300, 310 and 350 belt drives were almost certainly built by Micro (hard to miss considering the many design similarities), but it might be the case with the PD-444 direct drive as well. 

Also according to the vintageknob there were only a handful of manufacturers of DD motors at the time, which were used by all Japanese brands. Micro was basically a precision mechanical engineering company, so it is very unlikely they built DD motors or speed control electronics themselves.

I remember reading a TAS article some years ago describing the Japanese audio ecosystem, which over many decades evolved into a network of companies and designers closely working together. So plenty of overlap indeed as Totem395 suggests. It would be interesting to read a history some day on how this ecosystem operated and who were the designer teams responsible for the top DD tables we hold so dear.
