Re, bearing/ground path versus platter mass: The usual option is to use somewhat less than 150 lb platter ;>
, which is the compromise I opted for, for lots of swell reasons, one of which is because a lighter platter still allows for a realistic mechanical bearing/coupling that doesn't drag all that much and still lasts.
However, other factors being equal, I also believe that the heavier platter/lighter bearing is the superior idea. I'm still leary of air but see no reason that magnets and solinoids could not be employed to do the grunt lifting and holding-off-the-bearing-while-stopped, respectively. Base bearing could be typical carbide shaft and/or ball on zirconium plate, or similar, as long as it NEVER took full weight or a bump.
Never having played with an actual 150 ib. platter I wonder if it actually benefits from a "ground path" as much as, say, a 35 lb platter.
Now I'm wondering what is the curve for benefit/platter-mass. I know it's up past Linn, my own Sota Star, etc; but where does it start to trail way off?
