Maybe my lugholes are faulty, but all CDs recorded pre-1998(ish) sound 'orrible: tinny, bright & compressed. Try to avoid anything recorded pre-1998 that's AAD, ADD or DDD without any mention of re-mastering on the sleeve/case. And if you do find a pre-1998 recording by a maestro, then make sure it's recently(ish) been re-mastered & has blurb re 20- or 24-bit tech on the case/sleeve. For example, Yehudi Menuhin's 1959 release of Mendelssohn & Bruch's fiddle concertos now sounds mighty fine on CD cos it was re-mastered in 1998.
