I am in the same situation as Dmbaudio. Have had a RM 10 for many years, recently upgraded the cartridge to a A90 (from a Transfiguration Spirit) and the phono pre to the Avid and my dealer suggested the Classic 3 as a worthwhile upgrade. Since, I have the right to try it at home I will dive in. So far, I have not disliked any of his suggestions.
