Hi,
If he was talking about speaker driver design, then i can see what he is saying.

Microphony is only an issue for valves. Maybe poorly manufactured equipment where dry joints etc., are an issue. Else, equipment being sensitive to vibration is another subjective foo myth, which adds to the paranoia of audiophiles getting them to worry about stuff, rather than enjoy the music.

No he was talking about Hi Fi components…
Microphony affects not only valves but all electrical components, particularly where low level audio signals are concerned. Just because you don't want to accept it does not make it ‘foo’. 🙂

Hi,
No problem accepting that it occurs in solid state equipment..... if you have the link to the technical article with a report that demonstrates it exists.

Thanks and regards,

Well show me the technical article that states microphony ONLY applies to valves. And not for example….ceramic capacitors……..?

They are not ‘designed for it’….🙄

And no ‘proof ‘ for this statement either…so stop hiding behind semantics. 🙂

Microphony in electronic components has been known about for decades and is well documented, (Even Wikipedia has a page on it as it’s that common) however it is very small in solid state and can be virtually eliminated by correct design, (There is a reason Hi-End amps have a heavy solid case with damping feet) so you are not going to be able to hear it as it is dwarfed by everything else in the audio chain. (If you are paranoid just stick a rubber car mat under your components and the job is done)

As to valves (Tubes) just do the pencil test to see how bad it is with your particular amp.

NOTE: we are talking Hi Fi here not live performances, so forget about it with solid state. (No matter what some manufactures try and con you into believing)

Hi,
In reference to the wiki page, they do indicate ceramics capacitors are microphonic, but these should never be used in the analogue chain of equipment, since film capacitors are used (or should be).

Those film capacitors that are microphonic are not used - the ones used, the dielectric used is too hard.

It is easily tested, turn the volume up to maximum and no music playing obviously, and then tap the equipment with a pencil or other. The pencil tap vibration is much higher than speaker vibration feedback.
