JAM by Duelund

After adding the second pair of Jupiter Cu into my phonostage output, sound became more smooth and transparent by too polite and a little boring.
So, I decided I have to add more bite, more hot pepper to the sound of my phonostage.
I just ordered Duelund CAST Cu-Sn bypass capacitors...

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.
