Will a record weight harm the motor in a direct drive turntable?

Nice info but in practice, their measurements don’t corelate with my personal experience in SQ.

Platter run-out - +/- .001 inch is not a bad place to be when talking solely about the Stylus Interface within the LP Groove.

Additionally, the Vertical Axis is likely to be changing in conjunction with the Platter Run Out if the Run Dimension starts to increase.

Changes to the Vertical Axis is the one to show a concern about as this is where the noise is to be produced, and where a proportion of noise produced will be on route to the Stylus when in contact with the Groove.

As earlier stated by a TT owner " The goal, IMO, is to isolate the lp as much as possible from the bearing. "   

The vast majority of us is not going to know there is a problem with runout or the bearing unless or until he can see or hear a problem.  But yes, it is nice to know that VPI is paying attention to bearing accuracy in manufacture. At least one can be confident that a new TT starts out with excellent machining.

An interface where moving parts are able to touch is a one way route to changes occurring over time. The condition for the environment the parts moving are making contact in will vary. 

Inspection of conditions the parts are functioning in will range from Adequately Lubricated - No Evidence of a Lubrication that has a useful purpose - No Evidence of a Lubricant have ever been used.

Any of the conditions discovered means wear of parts is occurring when the Rotations are taking place.

Any of the conditions discovered means wear of parts is occurring at very different rates of break down and acceleration to becoming detrimental to the TT's Rotation Eccentricity, Speed Stability, as well as the Stylus function when within the Groove.

My aim as always is merely to encourage such concerns are not under the Carpet, they areas valid to be checked on a periodical basis as a Stylus Wear.
