True again - But, we're in agreement that these quantities don't always
relate to "good" picture taking or "good" art. I suspect that Jimi
Hendrix wasn't too interested in "accurate" reproduction of his guitar -
it would appear that in most cases he was after a certain "distorted"
sound and feel, which helped make his music unique.

Good point about the stairs, but remember, these types of guidelines or
"standards" are usually based on a bell-curve average. This leaves out
folks at the two ends of the spectrum, by design. For instance, people
with very short, or very long, legs might find the "feel" of a different
stair ratio to be more to their liking. I personally don't want someone
telling me what sound I should like, based on some calculated,
bell-curve, set of measured quantities, whatever they might be. Agreed,
the numbers are nice to know, and can serve to compare different
components, but in the final analysis, what matters is personal taste,
which I think we agree can't be "measured" very well.

Yup, I'd have to be a fool to disagree with that one. (Especially
regarding MY hearing). :-)

Yes, good analogy. I think we learned to live with clicks and ticks on
vinyl just because it was just there. Now with digital, we have the
ability to NOT hear it, so we're getting used to that. I guess that's
probably one of the reasons I don't listen to my vinyl much anymore.
Even though I took VERY good care of my albums, well, MOST of them
anyway :-), they still have noise on them which seems to bother me now
more than it used to.
