That magnetic floating table - I wanna hear the rumble on that!
The arm at the 13-14 minute mark is interesting...but any "servo" requires some error in order to "correct" and can't be geometrically perfect.
The designer was fascinating. Thanks for giving him the time, he seemed charming. I like that he says he's never heard it! (Like that old joke about Stevie Wonder's piano.)
It would be cool to make a mini-air bearing to put into the headshell on a pivoting arm!
You 'heard' it here first!
