Don't deny it. It is witchcraft! . 
Vintage DD turntables. Are we living dangerously?
Let me be clear that I never own an SP10Mk3 so I have no way of knowing whether it exhibits the gray-ish tone in Mk2. All my comments were referring to the Mk2 and the models below it. Just saying... I have limited experience with Mk3 as my former...

Thanks for elaborating, Richard. I am learning a lot about motor. Would you say the irritating "greyness" from the Technics is due to this high frequency "pulse" created by the feedback network? Can the remedy be applied to other brands of turntab...

Richardkrebs, I agree with you on many points especially about torque. And I'm glad that you are able to enjoy a modified version of the Technics. I just wanted to add that the higher torque the higher cogging and it's a challenge to increase one ...

Lewm: "The earlier Denons with induction motors: did they employ servo feedback as well? It is hard to imagine how that would work well. Did DP6000 use induction motor?"The one I'm know for sure uses induction motor was a DP-755, an old table with...

Lewm: "Someone else suggested that Exclusive P3 and P3a did NOT have a coreless motor. My information says they both DID."It does not look like the traditional pancake style coreless motor. Judging by this picture in this webpage, it might be a li...

04-04-14: Halcro:"If the TT-71 and TT-81 motors are the same......why have the two models?"While I cannot confirm they are the same -- the motors have different model numbers but, I believe, have similar structure -- there's really nothing unusual...

More observations I made earlier in the other thread. Here's the major clue from the vintageknobs page. Halcro did post some innards pictures of his TT81 but short of the inside of the motor. That TT81 looks awfully close to the TT71 motor. Yes, H...

That specs page is for TT-71, which the writer is assuming its motor is similar to the TT-81 and I can say the assertion that it uses a "coreless motor" is absolutely wrong because I owned several TT-71 units before and I have looked into the guts...

When I used the word "stubbornly," I did not mean to discredit Denon and Technics in their confidence of the maturity of their designs and technology. If they felt their chosen motor type resulted in good sound quality then there's nothing wrong w...

10-13-11: Halcro:"Doesn't it seem odd....if a coreless DC motor produces no cogging and sounds so 'fluid', relaxed and unfazed.....that a manufacturer would be foolish to even contemplate an alternative design?"You look at the release of the model...

03-25-14: Lewm: "... do you perceive that the TT-101 and the TT-81 have exactly the same motor? It looks from photos that the TT-101 motor might be different in size or in some other way from that of the TT-81. I know they are both coreless types....

Lew, this is the first time I ask such question: how does it sound? _______
