Default 47 labs Koma TT

Following a link from another thread, I saw this on the 47 Labs site.

I think the TT looks very funky, in a good way.

Just curious about people's opinions about the contra rotating platter and whether anyone can see a benefit in this appoach.

I'm also looking forward to reading the reviews once it's available.

Looks like they found a funky way to built a belt drive version on an old Sansui idea
Dual turntable record player with torque cancellation
US Patent 4425638 1984-01-10 SANSUI ELECTRIC

The idea was used in the XP-99

Thanks for that info, it's extremely informative. The 47labs design does not address the issues raised in information from Sansui.
