Audiophile quality. Was that made up by a marketing department? If it's well mastered, it's audiophile. We'll just go mainstream for a second. Check out Metallica's S&M. Excellent mastering. Also check out Dave Matthew's Band (later CDs) Also high quality mastering. Sting: a-freakin-mazingly good mastering. Guess what--these guys aren't all on the same label.

I am the Doctor, and THIS... is my SPOON!
