JAM by Duelund


Has anyone tried these new reasonably priced tinned copper caps from Duelund in any positions?

Yes, Audin is good, but he’s a bit boring for me.
OK I’ll try to start a Duelund bypass capacitor.
Bypass Silver (Ag) or bypass Tinned Copper (Cu) which one is better?
I have Bypass Tinned Copper.
They sound very tonal reach, vivid and musical.
I never tried Bypass Silver. But most of people like them a lot.

According Jeff:

" Now comparing the 0.01uF caps in context: The Sn-Cu sounds more vivid and colorful, with more emphasis on the first attack of a note in the upper mid-range (which aids things like melody & beat), the timbral textures sound a little more “real” to me, and more nuanced. They also “open up” the music in an intriguing way, and seem to amplify the “acoustic roughness” of music a little, which provides more emotional engagement. The Ag bypass caps sound smoother and less dramatic, are more elegant and softly nuanced, with a more laid back and distant presentation, a little bit like you’re listening from mid-hall instead of the front-hall like with the Sn-Cu."
I instaled Duelund Cu-Sn bypass capacitors into my phonostege, bypassing Jupiter 1uF output capacitors. Before that I did 3 days burn-in of Duelund Cu-Sn bypass capacitors in FryBaby2,
Yes I got what I expected. Vivid guitar and piano strings and much more real cymbals. But I lost violins main tone. It was sound like an upper-midange dominated over a lower-midrange.
I run FryBaby2 during 8 hours connected to phonostage input directly, bypassing SUT. FryBaby2 was working in lowest voltage MC mode. Phonostage was on, and amplifier was off. It gave a very significant improvement.
It make sound better, more musical all-around and the lower-midrange become more rich in tone too.
But still violin sounded a little too thin. Than I tried to change interconnect between phonostage and integrated amplifier from Acrotec 8n 2080 to Duelund DCA20 (with Duelund Cu RCA connectors) and DCA16 (Switchcraft RCA). Both Duelund interconnects made violin sound natural.
So, pure Cu-Sn Duelund solution works the best!
What I like about Duelund Cu-Sn bypass capacitors - they make sound savoury.
And even some bad or boring records start sound good and exciting.

I didn't try  Duelund Ag bypass capacitors . So I can't compared  Cu-Sn to Ag.
