I'm not sure about your amp, but I had similar problems with Maggie 3.5s and used several diffent amps from ARC to Bryston to Biamped Acoustat TNT 200s and finally a Levinson 336. The speakers went back to Magnepan several times for not only would the fuses go but so would the tweeter......
The spls were well in the tolerence of the speaker acording to my guage and I did try the subwoofer system and an ARC electronic crossover. Nothing helped.
Magnepans only recommendation (as per Jim Winey's son,Steve, who tried to be helpful) was to buy another pair of 3.6s to play while the orginals went back and forth for service. I finally fixed them one last time and sold the things. The speakers do sound fantastic for the money but in my opinion must be flawed. Maybe some units are defective in some undetactable (at least by Magnepan way), otherwise there would not be all these happy Maggie customers.
I owned the original MG-3s since they first were marketed with most of the same equipment and the same room, and only lost 1 tweeter in 14 odd years. The 3.6s sounded much better but were not reliable in my experience.
