Do you think Mcintosh gear would be as popular if it wasn't pretty?
For me ascetics are almost as important as sound quality. yes, you can have both. You look at your system almost as much as you listen to it. Plus if it's "pretty" your other half might have less issue having it take up half a room.
For me, I like unity, so if most of my stuff is black, the other pieces should match. Also meters and lights are pretty, so why not, again, Mcintosh.
For me the one exception would my turntable, will never buy a piano black one again, almost impossible to keep clean!
