I have experienced the same thing.
I replaced in my cd player my audience auricaps .22 @ 400v with the Mundorf silver gold oil at the same spec and I noticed the 3d reduced drstically- as well as the bass and the naturalness of the sound. The sound is more upfront- less spatial and has an empahsis in the upper midrange and high end. It sounds good but less pleasing that with the auricaps where i felt I was in the music. How did your situation pan out? Did you Mundorf's get better with time and burn in?
