Well last year when I first set up the XQ3s they were tight (can't think
of a better way of saying it) and had an odd balance which I found
disappointing. At the time as always I was using my much older Kefs as a
reference and they murdered the XQ3. After some hours of run in they
loosened up and became tonally much more similar to my reference.
You may say it was my ears and my non hi-fi mate's ears but I am sure
that was not the case.
Alas, you may be "sure" of something, but might still be mistaken. It does
happen. Happens to me, so I suspect it can happen to you as well.
I do accept they may well have measured identical before and after as
regards frequency response but they didn't sound it.
I'm sure you will not believe me but it was my friend who noticed they
were changing in sound before I did and he has no Hi-Fi or ever been in
a hi-fi shop or read a magazine as far as I know. He's into IP stacks
and cisco routers and such.
So far as I know, human physiology/perception is not 'taught' how to adapt
by reading about this in hifi magazines, etc. Hence the facts you recount
about your friend do not mean he lacks the naturally inherent adaptive
processes which physiologists have measured as being usual in humans.
I am not certain that you are wrong. Just that I see no reason to accept
that your belief is well-founded.
Just because it has not been measured and you've not heard speakers
change doesn't mean it doesn't happen.
However IIUC the situation (as you report it youself earlier in your
posting) is that measurements show no change in the speakers. This is not
the same as "hasn't been measured" since the measurements conflict with your
belief that a change in the speakers occurs. Whereas, measurements on human
perception *do* seem to show relevant changes which may explain what
you hear.
This group is the only place I know of where such things are not
accepted as normal.
Perhaps that is because some of us are swayed by evidence. :-)
I don't understand how people can be so cock sure that this does not
happen,
I can't say that it "does not happen". However I see no reason to accept
that it is the normal or usual explanation given the measurements, etc,
mentioned above. So far as I can see, what you report is consistent with
changes in your perception rather than in the speaker. Perhaps you are
right, but if so I suppose we could ask why you are so "cock sure" that you
are correct in your belief - despite the measured evidence implying the
contrary.
I presume it is based on their understanding of all the components that
make up a speaker. I myself am a sceptic about knowledge of this type. I
don't deny it is the best way and the only sensible way to pursue
development but to assume we know everything is not only arrogant it is
stupid beyond belief.
You seem to have jumped from a disagreement on one specific point to a
generalisation about assuming "we know everything". It is not necessary to
"know everything" to form a view on one specific point. All you have to do
is consider the evidence relevant to the point and come to a view
consistent with the evidence.
Science has a habit of changing its mind as better theories come along.
Not quite. Science does not have a 'mind'. The scientific method is a
toolkit for trying to develop improved models and understanding. The
'theories' are those ideas which have so far shown to be consistent with
the evidence.
For how many centuries did we believe the earth was the centre of the
universe, people at the time knew it was, you only had to look with your
own eyes. But they were wrong.
Since I am not included in either "we" or "they" above I'm afraid I can't
take that particular rap. :-)
However if you want to argue about ideas being "wrong" then I am afraid
that you are using a language that may lead to most ideas - including your
own - being found "wrong" in due course. At any point we can only proceed
on the basis of the evidence we have, and set about collecting more to test
further our ideas.
There are far more things in heaven and earth and some humility would
fit well with some people on this group.
Fair comment. If you wish to apply that "humility" to your own ideas you
might like to consider what experimental tests you could devise whose
results would show your idea is supported and falsify the idea that the
changes are due to changes in perception. This critical testing and use of
new evidence is the "humility" that is part of the scientific method. The
aim being that our theories are tested by evidence, not accepted on the
basis of being cherished personal beliefs.
