Since I will soon have a very powerful amp (XPA-2: 250 W into 8 ohms, 500 W into 4 Ohms), and I was thinking about maybe 'someday' upgrading to Planar/Ribbon speakers like the Magnepan. I notice that many people on this board have Magnepan's and so assume that there real good. I see that the models start with the MMGs ($599) and go up to the 20.1. I'd love to hear your comments about what you like or don't like about them.

Thanks,
Stan
