Vintage DD turntables. Are we living dangerously?

Lewm,
I know the whole sordid Continuum story directly from Mark.
He is an astute audio guy with a genuine love and passion for the possibilities.
He has always appreciated the damage that structure-borne feedback causes to most turntable-based systems and has been an admirer of Minus K platforms for many years.
He is in fact the Australian Importer and Distributor for Minus K so it is no surprise to see him develop a turntable with a Minus K 'built-in'...
Somewhat reinventing Linn...👹❓
And let's gets real.....no-one is going to reinvent a new DD turntable which can be built in a 'garage'.
HW did it with a cogless super motor that still can't match the performance of the 30 year old Victors and can't be made for less than $30,000...😱
Rockport came the closest with its Sirius III but it would cost $200,000 today and was somewhat let down by its tangential tonearm....

And yes....ventilation AND breathing space is a crucial requirement for most vintage DDs....but especially the Victors.

"Apparently, Mark Dohmann, one of the principles of Continuum, is now producing a tt on his own, for about $36,000 with a Schroeder LT tonearm, a relative bargain compared to the Caliburn."

That Schroeder arm is NOT an LT model. The headshell offset angle and the lack of extra pivot point at the base gave away that it is not a pivoting tangential or Linear Tracking tonearm.

The Schroeder arm appears to be a carbon fiber version of the discontinued Artemis Labs TL-1 tonearm.

Hiho, You may be correct. I found two sources of info that conflicted with respect to the nature of the Schroeder tonearm optionally supplied with the Dohmann tt. One claimed it was the LT; the other did not.

I don't have a Minus K or its equivalent, but one of my two systems is located in my basement on concrete flooring poured over solid earth. My subjective impression is that this has amazing benefits, compared to upstairs in my living room, where I would probably notice a Minus K.

Henry, are you saying the motor can't match the Victor or the overall performance, or both? I'm curious about the basis of this statement.

Here is the Feikert Speed App for the VPI Direct as published by Fremer in Stereophile and
here is the corresponding one for my TT-101.
Now all the Raw Frequency and Lowpass-Filtered Frequency figures are near identical for both turntables yet look at the General Mean Frequency comparison figures.....
The VPI Direct is 4.5 Hz above the 3150Hz Test Tone Frequency whilst the TT-101 is spot on.
Oh I know 4.5 Hz is tiny and probably irrelevant in the scheme of things BUT.....the VPI is using the most expensive and sophisticated motor for this application currently available and has 35 years of computer advanced technology to draw on yet can't match the accuracy of the 35-40 year design work of the Japanese Victor engineers...😡
But these Charts are not the most revealing part of the Feikert Speed App.
Here is the real time analogue print-out of the actual sinewave produced by the VPI Direct whilst tracking the 3150 Hz Test Tone. Ignoring the fact that it is well above the 3150 Hz frequency line.....observe the continually varying pitch of the mean frequency (a straight line is theoretically perfect) as it drops and raises tone. THIS is the real analogue graphic of the true speed-constancy performance of the test turntable.
Here is the Frequency Chart of my TT-101 and here is the long-term frequency chart of my TT-101.
Now tell me what you see and how the world of audio technology has improved over the last half century.....❓😎
