I kind of like the laboratory look of all the equipment arrayed around the room. Much of that equipment is built to look sweet as well as sound sweet. And, if one is showing off, having the gear in view makes it easier!
What I was getting at with the supertweeters: Sure, there is some audible sound above 20kHz for some people. But what source provides any usable signal in the stratosphere? Phonograph recordings contain useable signal up to at least 45 kHz, but I can't imagine any digital source being accurate above 20 kHz, even with a 96 kHz sample rate. I don't ascribe to the pure engineering theory that a waveform can be reconstructed faithfully with no more than two samples per cycle.
