In defense of Rccc
Amazing how stylus drag can make a belt stretch even when the platter mass exceeds 10, 20 or even 30 pounds, yet somehow unclamped LPs on felt mat do not slip on the platter!
So funny how the direct drive folks boast about speed stability, but when you see their rigs many (if not most) do not use clamps. They seemingly find it easier to believe a 10 pound platter and belt drive has less rotational force than a 120gram LP coupled to a felt mat by gravity only. Mmmm.
I did an experiment some time ago. (http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1181854929&openflup&74&4#74) From my own observation LP slippage (unclamped + felt mat) for 20 min of play amounted to only 9.235e-5 % - less than 1/64 of an inch after approx. 16,920 inches of grooves.
Im not saying folks dont hear differences between direct, rim and belt drives, but something else is at play.
