I have a set of 1.7s and drive them with a Carver AVR100 in a 20x25 room. I bought it new back in 1989 and recently pulled it out of storage (forgot I had it). Although it certainly isn’t a fully functional receiver by today’s standards, it does have a great amp, at 225x2 at 4 ohms. I think it’s a total myth that Magnepans "need" tons of power to sound good. I’ve never had more than 225w to them and only had 150w before I brought out the Carver. It’s far more important to have clean, constant power than to have tons of it.
