Rock deserves the best to reproduce it, just as other kinds of music. There are plenty of excellent sound engineers working in the business.
Excuse me, but I like Jimi, Janis, and "the Boys" to sound just as life-like as Callas, Tebaldi, and di Stefano. Eric's guitar should sound different from Buchanan's and Beck's (Jeff, for chrissakes). Fidelity is fidelity...no matter what you're listening to. If it's poorly recorded, turn it down. If you buy a colored system, you're penalizing yourself from enjoying the best recordings of the best artists. I don't detect a whiff of...snobbery here, do I?
