Duelund cast Pio Hybrid Copper/Silver or Rs series with Silver Bypass PIO

Hi,
I have Altec 604E speakers with Werner Jagusch crossover. I bypassed high frequency driver's part of "original" WJ crossover vintage capacitor with Duelund Tinned Copper Foil & Wax/Oil BYPASS capacitor. Sound improved a lot. It sounds like new, much more expensive speakers!
I'm thinking about buying Duelund RS capacitor.
What do you think, will Duelund RS capacitor bypassed by Duelund Tinned Copper Foil & Wax/Oil BYPASS capacitor significantly outperform "original" WJ crossover vintage capacitor bypassed by the same Duelund Tinned Copper Foil & Wax/Oil BYPASS.
Regards,Alex.

Yes it will. Jupiter copper foil will be even better with that wonderful Duelund bypass cap.  

Hi grannyring,

Do you think Jupiter will work better with compression horn driver then Duelund RS?
I mostly listen jazz and classical. I rarely listen rock. I don't listen "junk" electronic and dancing music at all. 
I have 300B SET DIY amplifier (6SN7-6F6-300B).

Regards,
Alex.

I certainly do think so.  I have compared the Duelund CAST to the Jupiter and I actually like the Jupiter even more. It is a wonderful sounding cap.
