What then is the point? I am still having trouble understanding that. It seems that only certain system types can qualify, horns or other high efficiency speakers, and low wattage SETs.
Or maybe not, even though it seems to be so in practice. Your list of things in post #5 of this thread (first page) is so vague that anything could and should qualify.
This point though is problematic:
"No analysis of the sound into bits and pieces, music experienced as a whole"
That is simply not how I experience music, period. And I never want to, it would make music utterly boring for me. I always look for musical lines that are interesting to consciously follow, which is also to analyze. Fortunately, all great classical music, jazz and a lot of rock, among others, has that. This is what makes music great and interesting for me. This is also what separates the great classical composers from the myriads of lesser composers that have been forgotten and dispersed by the winds of time towards the obscure corners of history.
Sure, this conscious following of all the happenings in the music hopefully is able to synthesize the music back into a whole at a higher level, as it reveals all the connections within it that create the overarching narrative that the composer (or improviser) intended. But this doesn't seem to be what you had in mind, since in your words your "experience of the whole" eschews analysis.
Thus I will probably never qualify for the experience of Natural Sound (TM).
So be it.
