I am also very interested in the 1.7s. I want to pair them with my Advents as rears and a 7500/990 combo. I would be interested in how the 2200 drives the 1.7s and whether they have issues at high volumes. In the literature I have found on them, it sounds like Magnepan went away from the mylar and now only uses the ribbon film throughout the 1.7. It sounds like it is a lot closer to what ML uses without a bass module. Believe it or not there is no Magnepan dealer in Miami. Have to go 75 miles north to get to a dealer who doesn't know the speakers exist yet.
