Mundorf silver in oil cap burn in?

We use these in the Manger 109-AG Silver edition loudspeaker - amazing performance!

That said, they do require a LONG break-in of at least 300 hrs. Ultimately, they are transparent, detailed and smooth without any grain.

Hi Ecka,
I had some Mundorf silver in oil caps installed in my Sonic Frontiers SFC-1 Integrated and was cautioned(?) about the initial harsh sound prior to burn in. It took at least a month, I do not listen very often, but were smooth as silk after that. It's been about a year now and I cannot tell you how great they sound now that they have settled in.
I hope this helps.
Thanks,
BJ.

A faster/less painful way to burn them in: Use either a tuner, or CD player on repeat(something with heavy bass drive on either). Turn on only the source and pre-amp and let them run whenever you're not listening to the system. Your ears will love you for it!
