Long time ago Sterophile used to interview musicians about their audio systems. Some examples, John Lee Hooker with a Technics midi, Charlie Haden with Linn and Naim, John Lurie with entry Luxman integrated, Yamaha CD changer, double cassette deck and B&W entry bookshelf speakers.
Completely different approaches and involvement so being a musician does not automatically support the will for a better system.
I believe all the above have good experience with live sound.
