ESP2009:
I may be leaning more towards the warmer, cosier sound although I still want a clear and airy sound.ÿ Maybe it's because I am getting older? Hmmmm, definitely 'work in progress' from this poster.
Great thread, but since we all seem to like wide soundstage with warm, clear and airy sound, then we either accept the Werther's Original hypothesis or come up with something more flattering than flat caps and zimmers. My supposition therefore (which is the product of only one beer and a packet of dry roasted) is that we're all on a journey towards a commonly recognisable hi-fi Goldilocks zone of moderation, and that this is not the product strictly speaking of age, but rather of experience.
Although individuals will exhibit certain differences, en masse I suggest we're all tending towards the norm, or 'average', represented by that Goldilocks zone. If we measure experience by the number of trials (some combination of frequency of listening and changing components), then we should find that the periodic preference deviations (to which we all seem to furtively confess) of those with lots of experience are less pronounced and more subtle than those who have less experience, who will veer around more wildly. What seems like occasional capriciousness is then still part of the same ragged journey towards the norm, and if we could ignore short-term effects and focus on the long-term pattern, then we'd see the deviations tending towards a central line of best fit as we gain experience, all inexorably headed towards that average or moderate sound.
If that sounds too dull for words, bear in mind that studies of human beauty ALWAYS show we think "average" looking people are the most beautiful - nose not too big and not too small, eyes not too close together and not too far apart. Sound familiar? Treble not too bright and not too dull, bass not too pronounced and not too timid.
However, economic factors and the number and type of trials we can undertake complicates the picture somewhat. So when someone finds a sound "lean" and someone else finds it "warm" they're both correct, relative to their own experience which is the only thing they can compare that sound against. You simply can't meaningfully compare views between people, but only for each person relative to two points in time within their personal stream of experience. Those two different people with different views are not therefore on a different journey, as it might appear initially, but rather on different stages of the same personal journey towards the Goldilocks zone.
Therefore, to answer the original question, it's only meaningful within our own experience and we'll all end up somewhere in the middle. QED. Obviously I have no evidence for any of this and indeed I feel a second beer coming on.
