It depends on what you include in "everything". IIUC, the individual ear-brain system is far too adaptive to be addressed by most measurements. So individual personal preference remains well outside the zone (although there are some statistical measurements referred to later on in this thread that do connect population preference to technology).
So underlying the issue here is, for me anyway, that personal preference remains outside the scope of ASR's measurements. Yes, largely. Measurements mostly evaluate defects against some standard of perfection (e.g. flat frequency response, zero non-linear distortion, etc.). However if someone prefers the characteristic frequency response of zero-order hold reconstruction (e.g. in a NOS DAC) then that deviation from flat is hardly a defect to that person. It's a big step in a much more difficult area than DACs and other electronics. It will be interesting to observe.
