Given the time taken in fitting the plate this could easily be explained
by listening at a higher level or the ambient noise being lower. Or the
coffee or alcohol kicking in. There are so many variables with a time
lapse both in circumstances and your hearing that I'm surprised you can't
see this.

All the above are, indeed, factors that you would want to ask about. I don't
drink more than occasionally and never to excess, and I drink decaff so that
rules them out, but you're absolutely quite right to ask. I didn't change the
level at all, but ambient noise in London is always present. Another factor I'd
suggest is tweeter/ear height - if you get up and sit down, you're unlikely to
be in the exact same listening position, particularly since in my case the
front panel of the speakers is 6'6" from my ears. The difference in ear
position could be 2 to 4" I guess, even sitting in the same place, which would
have an effect on the sound. These questions are certainly relevant, and much
more constructive than saying 'it's all in your head'.


What would be constructive would be to rip files to hard disc and
compare them, for loud/quiet and damped/undamped. Until you do this
and find a difference, the overwhelming probability is that it *is*
all in your head. Any properly trained psychologist would choose this
as the most likely answer, before chasing arcane 'resonances'.
