Musician vs. audiophile

As to musicians and  possibility of being tone deaf I think Beethoven said it best 'Music is a higher revelation than all wisdom and philosophy.  Music is the electrical soil in which the spirit lives, thinks and invents.'  I think he has proved admirably that even having lost most of his hearing he created proven master pieces in music.

I have a friend who studied music in University and composes classical pieces.  When he hears a classical piece of music, he appreciates how it was composed, the methods used by the composer in writing this piece. When I talk about HiFi he covers his ears, when I explained about PRAT he thought I was utterly mad.  We both like music also classical music, if I like a particular piece of music its purely from the music, if he likes the same piece of music, its because of the music and how it was written. He is not so concerned how the music is presented (HiFi) but much more interested as to the music itself and how it was composed.  Often he would say 'notice how the composer expanded on that one note or theme'  I sometimes think about famous musicians of all genres, apart from the recording equipment used in studios do they posses HiFi at home. Does Paul McCartney have a state of the art Ayre system at home or does Mick Jagger have a Naim statement at home or are musicians not so bothered about HiFi...?
