I own the MF-2250 and drive Vandersteen 2Ci speakers with them. The Vandies dip to 5 ohms and are 86 dB efficient, so they need 100 watts to really make them talk. It's the best sound I have ever gotten from my Vandies, and I use the C-J PV-14L and EV-1 to feed signal to the MF-2250. Couldn't be happier with the sound. I have power to spare, so they should be capable of driving Maggies as they are conservatively rated 200W at 4 ohms impedance. You can get new MF-2250 amps for $1295 at Spearit Sound. It's the bargain of the year in a power amp, as the MF-2250 combines the good virtues of tube and solid state amps. C-J solid state amps have been under rated for a long time. The new MF series has gotten solid "5-star" ratings on AudioReview.com, and are considered substantially better than the old MF series, which was counted as very good. They have an unbeatable combination of resolving power and musicality at their price points. You can't do a whole lot better at any price, I would say.
