After 50 hours, it was sounding pretty good, but for $4000 I thought it could do better. I checked the VTA again, and found I had less measured IM by having the arm going "downhill" from the pivot point, not parallel to the surface of the record. Subjectively, the slight harshness in the high end was gone! A difficult to reproduce direct to disk jazz record sounded as close to "live" as I think you can get with an LP recording. For this sample anyway, the optimum tracking force is 2.0 gram, right in the middle of the recommended range.
