I don't know any Rock musicians who are 'audiophiles', but ATC advertise in their website of their 'professional monitors' being used by nunerous famous Rock musicians in the studios, I don't know if that counts within this thread question. However if I was a HiFi Dealer trying to sell hi fi equipment to a customer who loves Rock I would play certain Dire Strait, Pink Floyd, and Gary Moore albums both studio and live - the reason because the albums sound so great on any system whether the system is on budget level or the ultimate high end level which gives me an indication as to how the artists wanted their music to be expressed. Dire Straits never fail even on very basic equipment...!
