For critical listening, I adjust the stylus tip angle to suit the record. No mention of this was in your post, so that might be something you have overlooked.
I wold also personally confirm that the turn table is level and set up properly. In a time where most people don't know how to run a record player, the person setting up your player might not be able to go beyond basic assembly.
Nothing against the famous name who set up your table. I would generally trust them, after all, I am not famous for Audio distinction and the are , yet in something so critical you must know it is correct. No matter who set up the table, you must understand that it is correctly done, since this is your starting point for all the sound downstream.
