I don't own Maggies but I am a huge fan of eliminating fuses. this is an expensive hobby and unless you are getting by on a shoestring budget, you can afford to repair things if they break. (the fuse is there to keep equipment from failing, but doesn't always do that job). There are 3 kinds of fuses in audio (that I can think of):
1. Mains fuse this fues in in the 120V main power supply line.
2. Heater current fuses in tube amps.
3. Fuses in the signal path to protect transformers, drivers, etc.
The fuses in the Magnapan are the 3rd variety. I think that fuses have no place in the signal path. while a lot of people don't agree with me about eliminating type 1 and 2 fuses above, there is generally not the fear of replacing the fuses in the Magnapan speaker that protect the drivers (usually the tweeters).
Some go so far as to rewire to totally bypass or eliminate the fuse holder, which has been criticized for being magnetic. I agree with that plan if you can but to just put a copper slug in the fuseholder will get you 98% of the benefit.
Go for it.
