How microphonic?, at what levels does vibration have an effect?
Automotive, military, aerospace kit all undergoes vibration testing, from what I have seen for domestic electronics I would hope that the vibration levels kit endures to be mild, and as long as resonances don't build up it shouldn't be a problem. Record decks are mechanical so different rules apply so need to be isolated from all external forces where possible.
Forgot about tubes after reading further, got a tube mono-blocks and over the years they have been mounted on a variety of surfaces from a proper Hi-Fi rack, paving slabs, Argos chipboard TV stand to the floor, now I think about it I have never really noticed any difference, my problem is enjoying the music and singing along! stops me from hearing my system most of the time...

I was going to have granite work tops in my new kitchen, then quartz, now though its polished concrete, maybe I should put my system in the kitchen, at least the wife will hear the difference!
I have future T-shirts in mind and they will be pretty funny.....I can't disclose product name quite yet.

JC and Dan, when are you going to take your stand up routine on the road, you could call it "the wife in the kitchen tour" or in Dans' case "The rock singer in the dressing room tour".
If you want to test your theory on the differences between bases hire an EMC lab, do some tests, if it is some electromagnetic effect it will show up in the radiated spectra as well as on conducted immunity and transmitted tests. Same with the silly Entreq ground boxes (or how to add an antenna to your system, EMC don'ts number 1.) discussed these recently as we are working on a couple of things where connecting to mother earth (ground!) will be hard. So we wondered whether these grounding boxes would help!!!! LOL A good test is get a length of wire, stick on end in your scope, the other end in your garden and enjoy the perfectly flat line on your screen...
What will they come up with next, as some of the items shown on the last couple of pages are hilarious at one level, their effect on the techno savvy younger generation is not encouraging them to become audiophiles.

maybe he meant that you need to throw the brick, therefore the effect will be directional.
Nor any details about your magic filters, its been quite a number of years now...
Just sell plain t-shirts and tell up they have a quantum message printed on them, that only the true believers can see..

Dan, I have had a number of experiences similar to your brick directional effect over the decades. Some of Jack's latest 'bricks' do amazing things, beyond my understanding, in front of several witnesses at a time. Been there, experienced that, but as we know, we get laughed at if we tell certain people about it. Still others, lurking in the background, might learn something new, or to at least trust their ears. '-)
And the really lucky ones might stumble onto the same fun fact I did, which is: The less I trust my ears, the better my music sounds.
How can one not trust one's own ears ?.
You were born with them and have used them all your life....you ought to understand them by now, surely ?.
Dan.
Some 'claim' to be sensitive to it. Yet to see any evidence that this is actually the case! Likewise electromagnetic sensitivity. All tests so far show a bit fat placebo reaction. Which is of course what the high end snake oil industry relies on.
This would be the dowsers that Randi offered huge amounts of money to if they could prove their skills..and they couldn't?
