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.

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).

Alex.

I bought Duelund RS for high frequency part of my crossover.
I did some burn-in using Frybaby2.
I like results. Sound is unbelievable transparent! Now my Altec 604 can be compared in this regard to Lowther based speakers.
I have second order LP filter for mid-base driver of Altec 604.

Will changing of capacitor in 2nd order LPF do the same huge effect?
I need 8uF capacitor. Will Jupiter VT Series capacitors good a match for LPF for my Altecs?

Hi @grannyring ,

Did you use Duelund copper or Tin plated copper wire?
