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.

Have experimented extensively with Axons, Solens, Dynamicaps, Mundorfs, VTV Ultratone, both TF & Cu V-Caps, and Duelund Casts in various applications including on my Magnepan 3.6. You might not like the sound of the Axons or Solens, but they are anything but glarey. I'd look elsewhere for the problem before you rip into your speakers. Read the description of Humblehomemadehifi which I think is a roughly accurate decription of these caps. I'm actually fond of some of the sound qualities of the Solens on the 3.6 ribbon tweeter even compared with the Duelund Casts (although the latter only have 250 hours on them). I'd look first at the non-Mullard tubes and silver USB cable first - cheap and easy fixes.

I had the kind of glare issues you are describing with my 1.6's. Treating the corners from floor to ceiling tamed most of it. When I replaced the 1.6's with 3.7's, I was shocked to see the glare completely eliminated. I have wondered if the difference is due to the tweeters on the inside vs. outside. If you have the tweeters, out, it might be worth trying them inside before you start modifying the speakers.

Seen several guys with same complaint cure it with Analysis Plus Oval 9 or 12 speaker cable. I thought Oval 12 OUTSTANDING with Maggys.

the above directions on how to remove the side supports are correct but the cap value is wrong ...its 115.8 not 116.8 and the best combo you can use is 3 33uf Sonicaps gen1.... one 10uf sonicap.... and one 6.8sonicap......Use a 10uf Dynamicap in the tweet position and use Alpha Core 1.4 inductors....and you will die 100 thousand deaths over the improvement. If you want pics and help just drop me an e-mail at prettypugsley@rcn dotcom
