I just upgraded my M3 by replacing the digital board with the MDx board. $720.00 shipped to my home from Bricasti. A noticeable improvement and a great upgrade if your M3 doesn’t already have it installed when purchased new.
A 20 minute board swap out and as I said, a noticeable improvement in sound stage, clarity, and in the midrange.
