I've heard audiophiles claim time and time again that what we measure does not reflect what we hear in a listening evaluation. I think Floyd Tool is the pioneer in conducting the studies for this, but who else as in a position of authority has led research into this field? It can't be mere opinion. I feel measurements largely do correlate with subjective sound quality but I don't think *all* measurements do. Some are more relevant than others.

What is your position?

Good work carried out by Toole and others aside:
Are there good measurement methods available that can prove that the spatial characteristics of two audio events will be indistinguishable in a blind test?

I think that measuring the behaviour of loudspeakers in a room (or microphones) in a perceptually meaningfull manner is quite hard. It is easy to find _some_ difference, it is hard to tag the relevant differences while discarding the irrelevant differences.

People tends to move their heads, and HRTFs can vary quite a bit from person to person. Sticking a single omni B&K microphone at "sweet spot" does not tell us all there is to know about a loudspeaker/room system. Toole advocates empirical weighting of on-axis/off-axis loudspeaker measurements done in anechoic chambers, together with physical analysis of room geometry, but I dont think that approach is necessarily "perfect"?
