Mike Trei is excellent.Is there anybody in the NYC area that does critical set up for pay or as a hobby? I got my strain gauge rebuilt and bought a USB microscope with screen to set it up. The cart sounds better than ever and little to no inner groove distortion. But with such an exacting stylus (I’m running the SG6 which has the highest profile) I’m sure I’m leaving some sound quality on the table, so to speak.
