The conversation we had with Ian was in regards to the M80's. Basically, a lot of parts to swap and it becomes expensive. M22's on the other hand.....

I have M22 V2's, and the new on wall 22's have a much better (to me anyway) upper end. I absolutely love the upper end of the on walls. Somehow they are both very detailed and smooth at the same time. I did not think this was possible.
