Berning uses switching power supplies, and he has done so for many many years. To my knowledge, he does not use tubes in the power supply, but the PS works in service to a tube circuit. If the PS were noisy, it would affect a tube circuit just as it might effect a solid state circuit. All of David's stuff is very wide bandwidth, tubes or no tubes.
Upcoming Technics SP-10R (100th Anniversary Model)
http://www.technics.com/uk/about/press/releases/20170830-sp-10r/
"Berlin, Germany (30 August 2017) – Technics has today announced the launch of the Reference Class SP-10R, its most premium analogue, direct drive turntable to date, which is anticipated to hit the market in early summer 2018. The news comes as Technics unveils a prototype of the new, cutting-edge turntable with the world’s top-level* S/N (signal-to-noise) ratio and rotational stability for the first time at this year’s IFA."
"Reference Class Turntable Promising Outstanding Results
The SP-10R features a brand new, coreless direct drive motor which, in addition to the two-sided rotor drive system that was used in the SL-1200G, boasts stator coils on both sides of the rotor, for a more powerful and accurate sound."
"The heavy platter features a three-layer structure consisting of brass, aluminum die-cast and deadening rubber, just like the platter of the SL-1200G. By optimising the natural frequency of each layer, external vibrations are thoroughly suppressed resulting in a beautifully clear and crisp audio experience."
"The SP-10R also features a new ultra-low-noise switching power supply, which, compared to a power supply unit using a transformer, is better at suppressing unwanted humming sounds and vibrations. The power supply unit is separate from the main turntable, preventing unwelcome noise from being transmitted to the turntable unit, for a sharper and clearer sound."
FIRST VIDEO with SP-10R:
P.S. Should we expect $15 000 or more ? And the new plinth comin soon?
Power supply looks funny, but the design of the drive is great, i think we should wait for the new version of the EPA-100 soon. Good news the GAE was not the last turntable !!!
