Magnepan 1.7 crossover capacitor improvement?

In my never ending quest to eliminate "glare" from all components I've recently realized that my MG 1.7's are a contributor. The crossover caps in them are nothing to write home about, a mixture of non descript caps including an Axon totaling 116.8uf in the mid range and an additional 10uf Axon for the tweeter. Since Axon is basically Solens which does have glare issues, I'm ready to move on. After snooping aroud it sounds like a mixture of Clarity ESA series/ 250V + Mundorf supreme replacements in the mid range and Mundorf Supreme for the tweeter would be a good choice. But i'm curious if someone here has already trod this path and found a different path thats reasonably affordable ( not Duelends and Vcaps...grin)
At this point I have glare about 95% tamed but there are still certain CD passages that cause that chalk board scraping sensation.

Jordi, I am very much interested in making improvements to my 1.7's and was hoping you share your experience / details / schematics of how you went about making those improvements. What type / make capacitors & inductors did you use in your crossover mod?

Thank you very much in advance for your help. Looking forward to hearing from you soon

Thanks,
Shahir

Thank you dfarmer. I replaced all the caps to Mundorf aluminum oil caps. 100mf, 10mf, 5.6 mf and alpha core 1.4mh inductors. I replaced the HF caps to Mundorf 10mf caps. The caps are still baking in but the clarity, soundstage improvements are amazing. They are ~ 3 - 4 db louder as well. As mentioned in this thread before, I am hearing the songs & movies a new way - they completely redefined the way these panels sound (in a good way). I also skipped the bass management on the Emotiva XMC -1, using the high pass (63hz) on my dual SVS PC 13,s. They made a lot of difference too as they blend in well and the phasing issues are now gone. I am eagerly waiting for my CC5's (center channel) & MMGW's for surrounds next week. Once the CC5 breaks in, I am planning to change its crossover as well😀.
