Modern speakers will relentlessly reveal badly-done recordings. If you haven't had your Axioms (or any speaker) for very long, it's a good idea to "break them in". Easiest way to do it is to put a cd in the player, press "repeat", press "play", and let it run non-stop for 48 hours at fairly moderate volume. Use a recording with a lot of energy as opposed to classical music with frequent quiet passages. After 48 hours, then start more serious listening. It should make a difference.
