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


I own the MKl version of the Crescendo and see the crossover uses all Acoustic Zen branded capacitors. Most are blue in color with the smallest values bring black. Does anyone know what company makes these for AZ? I did email the builder, but no answer. Love any information the community may have on this topic.

Steakster, I will give it a listen and thanks!

Audioman58, my thoughts exactly to be frank here. It was a ton of work putting in the parts that should have been used upfront after the speakers were built. Mills or other good resistors would have cost perhaps $3 each instead of $.30 cents each. A $20,000 speaker should use a $3 dollar resistor :)

I see this all the time in high end gear however and it does cause me to shake my head.

Audioman58, I still have the bass boards to upgrade. Each speaker uses two 1000uf, 100v caps. Yes they are low cost electrolytics. Any suggestions here? These boards have 8 ohm and 12 ohm 20 watt resistors which I will replace with 2 Mills MRA 12’s in parallel. But the caps? Not entirely sure a better electrolytic cap from Audio Note will help much here or not. Film caps in parallel would be very expensive and perhaps take up too much room. Not sure bypassing electrolytic caps with film bundles is advantagious on a bass crossover board. I know it works great in amplifiers, but crossover boards?
There's been a few of the Crescendo's on Agon FS at around the 9k mark. Is this a good used price for these speakers?

Absolutely a good price used for a great sounding speaker in stock form. It is a wonderful speaker! Along with the Harbeth 40.1 it is the finest speaker I have owned and I have owned many good ones! 
I agree with Bill, 9K for the AZ Crescendos is a very good price for what you'll get. Just my observation but this speaker impresses me more than the Wilson Sasha or the Magico S3 or S5 when heard under similar show conditions.  This is not meant as a knock on the other two speakers which are well regarded and popular,  just my opinion. 

The Cresendo with the right amplifier match is capable of producing beautiful sound that engages you. YMMV.
