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

To clarify, your question on the Duelund hybrid cap relates to my post in that they are made using the Duelund CAST copper cap with a silver foil bypass cap.....the same cap that can be purchased separately now. The cap I posted on above.

So yes I am confident the hybrid Duelund cap would be simply wonderful sounding.

Another approach not often talked about here is using parallel caps. Using larger value (10uF or so) caps, would be interesting to note if any boutique caps sound significantly better. Essentially self-bypassing.

Best,

this will be in the signal coupling cap 1uf 630v.

You say it’s a coupling cap in the signal path, not a de-coupling cap.
You should only use one quality cap as a coupling cap.
No bypass caps, as you will smear the sound because of the different behaviour of each cap at the overlap point (frequency).
It’s fine and encouraged to bypass de-coupling caps with smaller ones.

Grannyring...the duelund silver foil .01uf bypass is Amazing.   I think it's one of the best bypass cap that works wonder in any cap.   They make a huge differences in Any cap! 

George.... thanks for the info.

let say if i did use the hybrid duelund 1.0uf 630v for the coupling signal, which is basically a silver foil .01uf cap bypass with the cast copper cap?  So this will not work?  What is the differences between de coupling or coupling?  Can you Please educate me on this? 

De-coupling, usually goes to ground for power supply smoothing.

Coupling caps have the ac music signal going through them, never bypass them, and always best to use one only here, the most highest quality you can afford.
