The well known weak link in Magneplanars are the low quality crossover components and connection terminal hardware. This makes the upgrade path easy to follow.
On the MUG tweaks page, they have a x-over schematic for an "improved" MG1. It seems Magnepan, at one point, revised the crossover points for the MG1. The values are 20Mfd for the high-pass and .67mH for the inductor. Magnepan uses Solens in some of their models and they're usually the first parts swapped out in an upgrade. I used Jantzen CrossCaps bypassed with a .1Mfd Theta AudioCap on my MMG's for the tweeter panel and they sound great.
Two pair of 10Mfd Jantzen caps and a pair of Theta bypass caps will cost you about $28 at Parts Express and a pair of Jantzen .68mH, 15ga inductors about $23.
The new, higher quality parts w/the revised values should "Wake Up Maggie(s).
