Probably the least important thing to consider when auditioning new gear. As it was phrased so well in the movie Beauty and the Beast as well as Lukasz in an earlier post above ....."Beauty comes from within" Maybe that's why I listen with lights out so that I am not distracted by looking at the gear but rather listening to the music
Ultimately yes, of course, and I likewise mainly listen in almost darkness as your hearing changes when your eyes do less work..
But a missed opportunity to match the aesthetics with the expected sonics, IMO of course..
