Magnepan ribbons problems

I've been using a pair of MG3.5 since 9 years, and though they've been performing superbly, I keep getting ribbon rupture problems. Due to the lack of local dealership, I've been doing the repairs myself, using their repair kit, but has anyone else encountered such problems ? I need to change 2-3 ribbons every year.

One of the speakers I'm considering upgrading to is the MG20.1, but I'm concerned about the tweeter. It's a right pain in the neck to change it.

Cemil,
What kind of power amp are you driving them with? I have a pair of 1987 vintage MGIIIA with the ribbon tweeters, and they have been replaced once since new, back in 1992.

To follow up my previous post, the responses re: power are oh-so-correct. The MGIIIA (all 3.X series and up), demand power, current and finesse. I have driven mine with the Sunfire Signature, and the Aragon Palladium Monos, both put out >400 WPC. The only time the ribbons were replaced in mine were before I took ownership. Care must also be taken when moving or shipping these things: Use the magnetic ribbon protector strip even when moving them from room to room. They may be delicate, but they sure can sing.
