Reference 3a De Capo i upgrades

I want to know if anybody upgraded the tweeter capacitor of the Reference 3a De Capo i speakers.
As I know, Reference 3a now use Mundorf caps on their new Episode and Gran Veena speakers.
And how about Bybee purifies ? I also red the Ref. 3a now use them.
Did you try on the De Capos?
I will apreciate your experiences and suggests.
Get foam/felt surrounds for the tweeters.
Check member 'Ridgestreetaudio' system page , they have done some mods to theirs . They are speaker designers and builders .
If the De Capos do not have the AVM paint like the Grand Veenas, get some a paint the spiders, wires, and crossover.
