While I agree that the Audio Mod arms are very good, your Alphason arm, IMHO, is one of the best arms ever made. I owned a couple of the HR-100S MCS arm on different tables and always found them to be top performers.
In your setup, I might try a new cartridge first. Maybe a Lyra Dorian, Argo, Helikon or a Dynavector.
