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!

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.

I've never had a Mundorf or V-Cap leak on me.

Yes, very impressive natural presentation of music. V-Caps are also very good, it just depends on what one is seeking sonically. I’ve used the Teflon tin foil V-Caps in the past. Duelund CAST is my preference. YMMV.

I have a dealer that has been looking for a long time for paper in oil caps for my speaker.  The particular caps are probably 70 years old or so.  They can last a very long time, and some vintage caps do deliver sonically.

Only issue I've had with oil caps over many years was Jensen copper foil in Cary amp, well known issue with those caps. Duelund CAST is now my preference by large margin vs others.
