I hang with musicians, most of whom couldn't care less about hi-fi. Evan John's system was a boom box. Lots listen to music on their computer's speakers, any disposable money they get goes to buying another instrument. Unlike hi-fi components, vintage instruments increase in value over time.
The one audiophile musician I've known (a real good drummer, he's lately been in Albert Lee's band) had stacked Quads for speakers. One thing musicians and singers recognize instantly is correct timbre, at which Quads excel.
