Internal vibrations of the capacitors...

hello to all,
Today while I was doing breakin of two caps, a strange thing happened.
When I raise the volume, approaching the ear, the capacitor plays the song that is playing!
Is ike a very low sound and a bit distorted/smothered.
The two capacitors are a claritycap MR and a mondorf Silver/oil
At high volumes, the capacitor that further develops this phenomenon is the MR CC, the Mundorf sounds less.
I think it is due to higher internal resonances of the CC MR.
But, how is it possible that the CC MR vibrate more of the silver/oil ?
Claritycap is famous for the studies done by the industry to break the resonances !
This is a strange thing.
What do you think?

I think that it's a good reason for not buying handmade boutique capacitors.

High Grade Caps
I'll come out in the middle. You want a high quality cap with low microphonics, ESR commensurate with the crossover requirements, and relatively low inductance. That means encapsulated, machine-wound caps, high tension windings, with polypropylene being the preferred dielectric. Metal foil would be preferable to metallized.
Avoid any cap labelled "audio" or "audiophile" or any cap boasting of exotic materials- that usually degrades performance, which makes some audiophiles happy because of the added distortion and microphonics.
Stick with well-engineered mass-produced brands. Wima, Vishay, Panasonic, that sort of thing. -
How were the caps installed on the board? They need to be zip tied down tightly as the least. Also I have seen all kids of caps sing nothing new there.Absolute corruption empowers absolutely.

my question is different.
CC MR have behind one large study in collaboration with companies of speakers, to break down the internal vibrations
the Mundorf silver / oil does not have this type of study
my question is: why the CC MR resonate more than the Mundorf s/o if approach my ear to the capacitor ?
the study of claritycap is not served its purpose? -
Because of how the internal structure is formed how the cap is constructed and many other things play a part. Anyway you look at it the caps need to be firmly secured to the board if they were not during your testing.Absolute corruption empowers absolutely.

OP, please disregard the second post, this post was a quote from "one of those Nut's" that can either afford quality caps of is vastly ignorant on the subject or possibly tone deaf. I believe F1 was doing his best to rely this. If you film cap is "singing" to you I would check all your solder connections and traces for cracking. It is NOT normal for a capacitor to "self oscillate".

why, in the same condition, CC MR sing more then munforf s/o ?
perhaps the CC MR are not as good as they say? -
What are they mounted to and how are they mounted? Where are they located? Why are you burning in two different brands of caps?Political Correctness'.........defined

really i don't understand, my question is clear, so my words already written :
"my question is different.

the Mundorf silver / oil does not have this type of study
my question is: why the CC MR resonate more than the Mundorf s/o if approach my ear to the capacitor ?

not my fault if you do not understand -
Who listens to the capacitors themselves?
How about testing and judging them by listening to the speakers they're connected to?"He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." Friedrich Nietzsche -

you didn't answer my questions. What speaker, where in the crossover circuit do they reside.Aroundthesuond wrote: »really i don't understand, my question is clear, so my words already written :

Love it,
That sir is priceless.
Thanks for posting it will be on my office computer home page come Monday morning.

And sorry to the OP don't intend to offend anyone. -

Maybe that they'll explain that you're supposed to be using speakers to listen to music, not the caps themselves?I'm going to suggest you contact Clarity. I'm sure they would interested in your findings.

What caps have YOU tried?
The ones the SY recommends would be a good start.
It take's big manufactures with big expensive machines and a big quality control department to make good capacitors. -

Hello,
There can be a combination of circumstances where a capacitor can be microphonic or piezoelectric. For example a signal capacitor in an amp carries an AC signal, but if it has a DC voltage on one side it can behave like a condenser microphone. The DC voltage polarizes the capacitor and the AC signal becomes the vibrating source.
In other words, no, it's not unusual for capacitors to be microphonic.
Regards, Ken -
thank you very much for your reply, kenneth,
I would like to understand why the CC MR are more microphonic/piezoelectric than mundorf silver/oil
should be less than the others, but isn't so, why, from your point of view ?
CC has done an extensive research on internal vibrations of caps...
