Frank I like to quote some out of your first post:
Auf alles was davor liegt, hat der Hifiist keinen Einfluss.
A few years ago a friend started a Hi-End showroom on an industrial park here in town.
To keep things short:
At daytime the sound was awful.
Late in the evening when the industrial workshops where closed the sound was SPLENDID! 
The end of this story: He gave up his showroom there.
