Dear @chakster : """
Most of the professional musicians does not have a perfect pitch! """
Could be but I don't know for sure. What I found out with some professional musicians ( some friends of mine, including a Symphonic Director. ) is that over years their ears losted accuracy and the frequency range goes more and more limited/reduced. The main issue is not because they are older gentlemans but because oever the years they are exposed to extremely high SPL for continuous time.
""" But i believe we cannot hear when 33.333 rpm spins at 33.332 rpm. """
As you I think is almost imposible to do it. Our brain perceives that tiny unstability but what we listen in that TT condition the brain can't be sure if it's by speed unstability or for other room/system characteristic.
Dear @frogman : """ is sometimes identified by audiophiles by some turntables being perceived as “livelier” than others. ........................................................... it is one of the things that causes preference of one turntable over the other depending on individual sensitivity to these problems. """
I think no one can be sure on what you said because there are to many parameters invloved down there. An analog rig is not only the TT and that " livelier " or " preference " can comes to from: cartridge, tonearm, IC cables, phono stage, that LP recording process because the speed unstability can comes from there and not from the TT it self, analog rig set up, etc, etc,
To aisle a problem of TT speed stability must be do it in a " scientific " way through measures in the short and long intervals of time or can be identified when that unstability is a gross one.
The other subject is that we have to take our time to be trained in our room/system to identify that critical " timing ". Not an easy task.
