HiFi for musicians

Hi, i'm curious if there are any musicians out there who are into HiFi and want to know if their musical training or habits have any influence over their purchasing decisions.  I'm a guitarist and do think i buy tube amps because i'm used to listening to them.  Not because they are magical, just because i'm used to them.  I often practice in the evenings and then listen to my stereo afterward because i want to hear a recording of someone playing something different than what  i was playing.  Do piano players buy piano black finishes?  Do horn players use horn speakers?  Just curious.
