Are we getting somewhere?
Pubul57 states that "the "gap" is small", so I feel secure, now, in inferring that we're likely well beyond Edseas2's and other nay-sayers' 5%.
Let's look at it without prejudice: on an absolute scale, 5 of 100 per cent would produce a recording of a piano that sounded like Linus' toy instrument. We have far better playback than that today and have for many years.
The indisputable fact that we have no way to measure the more far-reaching and seemingly esoteric or obscure aspects of our marvelous minds' response capability does not reduce the joy of listening --or the pleasure of a fine and pointed discourse, for that matter.
'Progress', as Kirkus and Atmasphere describe it, *is* happening, whether Edseas or his violist friend accept it. We're beyond 5%, like it or don't.
Luddites were against technology on a religious basis: in philosophy there is no religion, nor is there, directly, religion in scientific reasoning (at least at our present level of understanding; there may be marvel or regard, but that is different: vis Hocking's "Into the Universe").
Edsea2's objection to the 5% solution appears unscientific, and though some of the more esoteric tweaks in our endeavor appear to revolve around witchcraft, I don't care: if my listening experienced is enhanced toward my goal of playback sounding more like live music, I don't care what kind of "weird sh*t" goes into, is placed upon, or comes out of my transducers.
If you can't quantify it, but it works with concensus or others' verification, that simply means our science lags behind our listening pleasure in the ability to measure what sounds convincingly authentic to the live source.
Is that a bad state of affairs? Not knowing why something works?
I submit that having something work --well beyond 5% efficacy-- is cause for celebration. I'm grateful for the pleasure and solace, not to mention the mood-changing opportunity that my music system offers me.
I've thought about it, been frustrated by it, and exhilarated as I learned to 'tune' it to [something approaching] its potential. I enjoy learning, talking and writing about it. The delight it gives me, however, comes from listening into the music, and out of myself.
Best Wishes for Festivus, whichever flavor you prefer. May there be satisfaction in your listening, and joy in your heart.
