What stereo equipment do respected musicians listen to?

All/most of my respected musicians listen to the tight slap of English Leather, or they listen to nothing at all (but here's an exception).

I know a bunch of audio engineers and record executives who love Von Schweikert speakers and McIntosh amps and pre-amps. 

For years I work with, for and around world known musicians, and not a single one of them owned a stereo that was worth a damn. When they wanted to listen to a finished product that would be representative of what a consumer would hear when purchasing their albums, they came to my house.

This brings up a fundamental difference--do you listen for the emotional experience that music evokes, or to hear the detail of the janitor sweeping in the room next to the studio ;-) Now it is not that simple but music over a car radio can evoke an emotional experience, but clearly listening for detail is an intellectual experience.

Learning to play an instrument is intellectual/left brain, but I suspect for musicians it is more an emotional/right brain experience.

Wilson speakers tend to be favored by musicians. Note the above post. Possibly one of the reasons I like mine. Musicians ears are like most, they want to hear what sounds good… to them. The reference point might be a little different, but the goal is the same.
