Acoustic Zen Crescendo speaker crossover capacitors ... who makes them?

Hi Bill,
I can appreciate the time and effort you put in accomplishing this project,  very nice work. You are right,  this is not a simple crossover by any means.. I know how well the stock Crescendos sound.  With the improvement via better parts it must be quite heavenly.

Jet, those TC caps are the best I have heard in a power supply! Hard to fit because they are so large however. The Arizona Blue Cactus caps are wonderful for coupling. Wonderful tone.  

Charles, thus far the improvement is so gratifying. My wife commented last night that the system sounded beautiful and the presence of the performers was an obvious improvement. 

Granny you remind me of my DIY friend Tony Ho. He solders all connections directly without any rca or speaker jacks. He even makes his own High purity all silver wire that he hand braids with cotton. I think you need to do this next. I would not recommend soldering direct for AC sorry that is too dangerous and not worth it my friend.

your ambition paid off...really great to hear this!!!...pun intended.
