Boutique caps in oil... reliable?


Hi Everyone,

Just kind of openly curious.  On occasion I will read a post here or there that a boutique film cap which uses oil as a dielectric has leaked (i.e. failed). 

Just wondering when it comes to these high end oil impregnated (or maybe even wax!) caps what your experience has been with long term reliability.

 

Thanks!

Hi Charles,

I never hears of this DAC before, so I looked it up. I looks amazing, and right away reminded me of Audio Note, although reading the text it appears that it is its own thing, although I was glad to see that there was no oversampling, because I think that is where the magic begins.

What led you to choose it?

I have nothing but good to say about the sonic performance of the Duelunds. Organic, beautiful, and zero electronic signature. Well worth the (gulp) price.

There was a thread that I contributed to just yesterday where I mentioned that I had an expensive Duelund capacitor that leaked, and I got no satisfaction from Duelund or Parts Connexion. I had discovered the leak when I opened the DAC to change a tube. I left it in after cleaning up the leaked oil, and a few years later when I sent the DAC in for an upgrade, there was no more leaked oil, and the technician tested the cap, and i was still up to spec, so no harm done, I guess.
