What causes microphonics ?


I have a Rogue Magnum 99 preamp. Sometimes it exhibits microphonics, and sometimes it doesn't.
I have found this very difficult to eliminate. I have tried numerous amounts and types of different tubes. It still comes and goes. One time I turn it on , and no problems. Next time, it's there.
Also, does this effect the sound ? I would assume it does in some way, but I am not positive.
Thanks, any info would be appreciated.

I have heard of this from other people that have that preamp - I suspect something in the design or constrution of it.
