Interesting that such a simple methodology is unchallengable.

I conclude that the argument has been settled in favor of idler drive
turntables.

The Garrard tables as well as the Russcos and other DJ battleaxes of
old were idler drive, and worked pretty well until the rubber parts got
flat-spotted. Correctly set up with new rubber they are charming
antiques and work halfway decently, but no one in their right mind
would take a Garrard over a LP12 for sound quality.
