I was ready to pull the trigger on this TT -- finally, it seemed, a modern-day turntable manufacturer taking vibration seriously (as opposed to the bolt-the-motor-to-the-plinth or the half-ton-of-aluminium brigades) -- and then I saw Fremer's Munich 2015 video (https://www.youtube.com/watch?v=LRGLXOFQKb4).
Extraordinarily, despite the amazing Minus K tech incorporated in this TT, they put the motor ON the subchassis. Listen to the video at 4'.05'', where the Dohmann rep describes the motor being on the same plane and "...moving with the suspension", and then again at 4'.25'' where he describes this motor being "...off-the-shelf" and "y'know, nicely made". For real?! A cheap-ass stock motor plonked on the subchassis that bears both the platter and arm? This rep describes the Helix as being effectively immune and isolated "...from ground-based vibration", but this is smoke-and-mirrors as, while the Minus K's usage in SEM and EFM microscopy speaks to the utility of this anti-vibration tech, the principal source of vibration in a turntable is not 'ground-based' -- it is WITHIN the turntable, i.e., the motor, and thus this groundbreaking tech is largely bypassed.
Watch the appropriately-named video 'Famous Minus K Wine Glass Demo Described' (https://www.youtube.com/watch?v=evAx-1rv4lQ), and marvel at how how this extraordinary device isolates a filled wine-glass placed upon the device from the stated earthquake-level vibration beneath it. Then wonder how this amazing device would work if the vibration source were placed UPON the Minus K along with that wine glass, as in the Dohmann Helix.
Show me a Minus K video with both the undisturbed wine glass AND the vibration source on the Minus K and I'll buy it (literally), but this Dohmann TT is not, at least per the Company rep's description, implementing the Minus K in the way that it was designed to be.
This is the Rega model of isolation...
