Same thing happened to me when I bought my Axioms. Almost all of the CDs I already owned sounded like crap. Originally I started buying SACDs and DVD-As to get quality recordings but after demoing a bunch of CDs at the shop I bought my headphones at I realized that well mastered standard CDs sounded just as good to me as 2-ch SACDS.
