grannyring  Do you use Jupiter copper in a passive crossover acoustics or in an amplifier? Sorry for my bad English, I could not understand this by reading your discus discussion.

I use Jupiter capacitor in phonostage built by EAR 834p schematics (with some upgrades).
The first pair (left and right channel) of Jupiter capacitors  I use between 1st and 2nd stages. The second pair I use between 3rd stage and output.

Someone tried Jupiter copper as a crossover capacitor for an acoustic system? How are sound impressions?

I used them in both. Yes they are fantastic in both passive crossovers and electronics.   

I will try to replace in passive crossover my Audyn True Copper Max with Jupiter Cu. And I’ll look at the result. In this test, Jupiter Cu scored 1 more than Audyn Copper Max. http://www.humblehomemadehifi.com/Cap.html
