Isolation for electronics, why is there no evidence?

Hi everyone,

Something has puzzled me. A very very long time ago I had a Radio Shack phono preamp. Don't worry, it wasn't attached to anything good.  I was probably like 16 or something. Anyway, despite being solid state the preamp was incredibly microphonic. You could flick the thin top and the speakers would ring like a bell.  Clearly something in there was modulating the signal. I've heard since it was probably the cheap ceramic caps, but whatever, something was causing the ringing, and no it wasn't hte turntable picking up the preamp movement.

IN any event, of all the snake-oil like theories of audio one that would seem perfectly testable is finding out just how succeptible a given piece of equipment is to vibration. Put it on the floor, measure the output of music.  Repeat without speakers connected.

Somehow, somewhere we should be able to come up with a way to measure it, and maybe create entirely new classes of products that are not microphonic, or have it be part of regular reviewer testing.  "Why, I love the amplifier, but it measured 0.8 on the Erik scale, so you better get a good stand....."

As I get older I'm getting more sick and tired of equipment that requires so much care and feeding. I want it to be bulletproof and work anywhere, kind of like the Omega space watches.

Thoughts?
