Hi Peter no chatter and zero vibration, you can "hear" this in the stellar resolution this arm has. Other arms I had to remove damping troughs, fine vtf weights, anti skate mechanisms even finger lift b/c they chattered, rattled or colored the sound. The magnets keep the bearing in the underneath race centered in the race so they never touch unless your physically moving the arm by hand to its rest position.
Hope this explanation helps
