What stereo equipment do respected musicians listen to?

I can't keep my finger shut on Mr. Douglas's "How stars listen to music:" article.

3 of the 13 acknowledges the speakers.  4th clearly shows both of them.  But not mentioned. 

"Frederick Douglass is the senior home entertainment expert and focused on reviews. His specialities are: technology and home theatre systems."  Not so much into Speakers of a system..

"They probably listen much more to the notes than the sound of the instruments."

Speaking for myself, I am very aware of every Note and Sound that is coming from Me.  As well as the notes and sounds coming from others in the band or orchestra.
