Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil

Why do you need all these Mundorfs after using Miflex KPCU?
What was wrong with  Miflex KPCU?
Did you try Jupiter Copper?

Does anybody try to bypass Duelunc Custom Cu capacitors 
with Duelund Bypass Sliver or Duelund bypass Cu-Sn?
How does it work?
Which kind of  Duelund bypass do you prefer?

Teflon is a kind of plastic.
Any plastic adds plastic coloration to sound.
Even for wires isolation cotton sounds more organic and natural that Teflon.

I tried a dozen different polypropylene capacitors.
All of them have "plastic" coloration. 
In term of tone, smoothness and musicality paper is oil capacitors always bit polypropylene  capacitors.
I never tried Teflon capacitors.  Teflon isolated wire sound good but less natural compared cotton isolated wires.

Hi @grannyring ,

Can you described a sound difference between:  Duelund Silver VS Sn-Cu bypass caps?

Hi @grannyring ,

Thank you!

Hi @c_avila1 ,

I’m agree with you. Everyone has their own system and taste. So the best way to try by yourself in your system.

@kalali ,
IMHO, the value accuracy of coupling capacitors is not so important. Is doesn’t matter to much if cutoff frequency 1 Hz or 2, 3 Hz.
The quality and sound signature is much more important!
The other story in crossovers and RIAA correction where accuracy is the must.

It is mistake.
For R=100K and C=0.68uF F3 is 2.34 Hz

You need to try yourself, in some cases bypassing can work good in some cases bad.

In my case, Jupiter Cu 1uF works very good with Duelund Cu-Sn bypass 0.01uf on my phonostage output.
Probably, if I used a single Duelund Cu-Sn 1uF capacitor, it would be even better. But I didn’t try it.

In my speakers HF crossover I bypassed 4uF Duelund RS with the same Duelund Cu-Sn bypass 0.01uf. In direct comparison, when I remove bypass sound has a better focus,
but with bypass I have much more vivid, real, alive and musical sound.
