Update on the duelund 0.01uf silver foil meant as a bypasscap.
Finds on getting bore extension is as previously stated.
This is a very neutral cap and balanced sounding which actually does'nt add much as a bypass.
I have retested in a different application, digital input as a small value of 0.01uf is sufficient. The main comparision is the jupiter copper which used on it's own is one cap i find the most neutral and balanced sounding accross the whole frequency range, it was however a 1uf replacing the 1uf electrolytic.
The duelund as a main signal cap is slightly more detailed and clear whcih leads to a more upfront and less open sounding compared to the Jupiter copper.
I must say without critical listening, they sound very similar ,but currently have preference to the more layered and spacious sound of the Jupiter copper although with a penalty of a slight loss of detail of the duelund silver.
The silver duelund does not have the typical lush and analogue mids of the cast cu and still a very fine sounding cap with better extension on both extremes, so it is balanced over the whole frequency band. Does not sound bright or lean. Do not expect the bass resolution of a teflon cap like the tftf.
Do note, unless you can use the small value in coupling, it should help bring good details as a bypass, but likely not additive to tone or high. A very fine sounding cap which probably needs more time to see if the staging can be more open and have better depth, otherwise, it very good in all if it can be used in a very small value.
