Pbb, maybe all the empirically verifiable statistics one can gather about any given phenomena still have to be perceived through our individually variable sensory inputs and therein lies the inability of statistical data to accurately describe a given individuals perception of reality. A speaker may measure absolutely flat in a given acoustic environment, but depending on volume level, hearing acuity or loss, and a host of other factors, one might find it deviating from one's ideal of "accuracy." I think John's analogy to food is apt, he's simply saying we all experience things differently. One could do a spectrographic analysis of all the chemical compunds in a given sample of ice cream, but would that tell how it tastes? That's not an entirely appropriate analogy, but you know what I mean. Statistical analysis is a useful tool for design of an item to be used in the service of art, but it's hardly an objective description of that tool's total performance. Jeez, scientists have been trying for decades to unravel the mysteries of the Stadivari and Guarneri violins. All the engineering drawings, wood analysis, varnish spectrographs, and frequency analysis have only left us scratching our heads at why they sound so wonderful
