Lloyd Walker tells an amusing story that some of you may have heard... he was demonstrating his Proscenium turntable at a show a few years back when some attendees came in to talk with him about why he didn't use a high torque direct drive design for his table.
Their argument was that only such a design could maintain the pitch stability and drive that music required and that any belt driven turntable (such as the Walker Audio design he was demonstrating) was fundamentally flawed in design.
Lloyd was playing a piano recording at the time (certainly a good test of pitch stability). So, rather than spend a lot of time arguing, he pulled out a pair of scissors and CUT THE DRIVE BELT.
The record continued to play with no discernable change in pitch for at least 20 seconds.
And thus ended the debate.
NB: I own a Walker, so I've got a bias. But I've done the belt cutting routine here just to test Lloyd's story. Amazing what a virtually frictionless high mass (80+ lbs) platter design can accomplish with an extremely low torque motor. (Agree with you on this Seandtaylor99.)
