Fuse upgrades for Magnepans

Does anyone have experience with upgrading the fuses on Magnepan speakers? I recently traded my 3.7is on a pair of 3.7X. I’m very happy with the improvement but they use the same, inexpensive, glass fuses that were in the old pair. You’d think the fuses would be an obvious place for the X upgrade if there were benefits to be had. If you’ve played with fuse swaps on your Magnepans, I’d be interested in your impressions and what fuses you’ve tried.

Here is what I use in my LRS’

Thanks. What benefits, improvements would you say you are hearing with them?
