Why According to some Turntable extremists Pitch Control and Direct Drive is Sacrilege?

Melm,  so, where is it that I don’t know what I’m talking about? I own an eagle and road runner. Together they run my Lenco very well and accurately. The servo device in the Kenwood L07D also has a loose operating point in that it only makes corrections when speed has slipped a certain amount and that’s part of the reason for the large heavy platter, So that rotational inertia as well as the servo feedback serve to maintain a constant speed.. My point was that since modern turntables of all types are more and more adopting speed correction devices, it hardly behooves one to criticize vintage direct drive turntables  for employing a servo feedback mechanism. I said more than once in my previous posts that some of them work better than others. So what do you want from me? Maybe it’s best not to preface one’s remarks with an insult.

 Also, I am not certain of this, but I might take issue with your description of the function of the eagle and Road Runner. The manual says that there is a blinking light in the road runner read out that indicates when a correction is being made. During run up one sees that light blinking with at least every revolution. Once approximate correct speed has been attained, the light blinks much less frequently but still irregularly.This indicates that there is more going on with the eagle and roadRunner than simply making a correction every three rotations of the platter. 

The torque of the motor,  has NOTHING  to do with the perceived   dynamics of a turntable.  Also , belt drives when properly  designed  can match the dynamics of idlers and dd's, so let's not kid ourselves about inherent superiority. if there is a "magic bullet" it is
BEARING DESIGN

13blm,  just to continue this conversation, I would point out that the bearing of a belt drive turntable is under a unique stress that does not pertain to direct drive and most idler drive turntables, in that there is a sideways force pulling on the spindle shaft. In theory this could cause uneven wear, and eventually result in a minute amount of wobble. Not to mention that this force in the horizontal plane can also add noise. I am bringing this up for fun debate purposes only, not to get your goat.

My goat is hard to get, but shows up occasionally. 
The forces in well designed  oil and air bearings essentially  prevent what you described  above. There is no contact, or wear or "tilting", generally. my bigger point is bearing design accounts for much of the sound of a turntable especially  in dynamics. Low friction bearings make low torque motors look huge, extra torque just adds noise and cogging

( Btw, I have my company  idled right now so have nothing to sell)

In belt drive, fast spinning motor has vibration, rubber belt has compliance, and plus to it friction of a needle on vinyl in not a constant.
You can get an ideal belt drive only in laboratory conditions.
I like idler and good DD, but I hate belt drive like many other modern Hi-End delusions like:
low sensitive box speakers, bright tweeters, 1KW transistor amplifiers, $10K cables ...
