Fuses on Magnepan .7 speackers

I have a new pair of Magnepan .7 speakers and have heard that the fuses in them are low quality and that I can actualy improve the performance of the speakers by replaing the fuses.

What the saying about there is one born every second!!!
Boy that's the truth. Spend your cash on music
Hardcore Maggie enthusiasts on the Planar Speaker Asylum Forum discuss bypassing the entire fuse assembly in their Maggies. Some of the parts are ferrous! Even if you change the fuse, those parts are still compromising the ultimate potential of the speaker. 
I’m having difficulty finding a relatively inexpensive (under $50US) large 5A fast blow audiophile fuse to replace the mid-range fuse. Some of the suggestions above seem to be for slow blow fuses. Thanks in advance. I’ve 3.6Rs and a Bryston amp.
