I just upgraded my tube amp (Double mono KT88) with 4 new capacitors Mundorf Supreme Silver Oil 1uf 1000v and was thinking that it would be good to share a little feedback on them. :)
Technical specifications (according to manufacturer): "The MCap® SUPREME silver/oil is an oil impregnated metallised polyprophylene dielectric capacitor. As the name indicates, high-purity silver is used for the capacitor coating, and the winding is impregnated with a special oil developed in an exhaustive series of experiments and listening tests. Both these features contribute to an even fuller and smoother tonal richness and diversity. Our state-of-the-art metallised polyprophylene foils make it possible to maintain extremely low production tolerances that cannot be achieved with traditional oil/paper capacitor designs. This is also the first time that the benefits of oil-impregnated capacitor design have been successfully combined with the well-known long-term stability of polypropylene foil and internal series wiring for induction-free SUPREME performance. Its lively reproduction of music impresses in particular with its subtly dynamic speed, precision and marked fine detail."
The Sound: Very smooth and EXTREMELY detailed ! Very defined bass and not "boomy" at all.
As they are in the amplifier for less than 60hours and as it is recommended to wait AT LEAST 300h for a proper running-in, the sound is still slightly "clinical" but it's improving everyday ! :)
Update: They are now fully run in and the sound is just Magical! Deep, precise bass and so much more detailed than with my previous caps ! Love them ! :P
nb: Please note that if you wanna give a try with them for your own amp, take in consideration their size coz they're huge !
