You could make the case that hearing is more acute than sight. Before the discovery of fire, humans would rely on hearing to keep them safe at night. Good hearing would have been an evolutionary advantage.
Forking from the cables thread to a discussion of whether hi-res is audible.....
While on the subject of embarrassing testing...
Let me preface this by saying I have invested in hi-res audio tracks, both on my server and in my Qobuz subscription. I've always felt I could tell the difference, although there are duds in hi-res just like redbook. And some great redbook recordings.
Going through this test, particularly looking at the control groups, is certainly humbling. I particularly like the "hardware reviewers" group.
