Isolation tables/stands for valve monoblocks?

They're fine, but make sure the stone was quarried in a particular location, at 3pm on a Wednesday afternoon in late August, otherwise it'll play merry hell with your electrons.

 

Indeed, and they should be transported from the quarry within a magnetically shielded container, just in case the lorry should pass under any power lines in anything other than a perpendicular direction.

 

I had hoped that would have gone without saying. Plus, of course, the lorry driver must be called Pete.

 

That would take me several days, after which I would put the boards behind the sofa for several years, rediscovering them at some future date and thinking 'what the eff you see key is this?'

 

I'm sure that they would also provide benefits from behind the sofa; I imagine they would probably increase soundstage depth and resolution, certainly for anyone sitting on the sofa in question. So removing them from this position would be quite a mistake.

 

Indeed. Actually, such would be the inky blackness behind the sofa that I would probably never find the boards anyway.
