If you are worried about fatigue, you probably should have returned the Axioms, as they are known as being a little bright. Also, you may want to check out the September 2004 Stereophile magazine where Sam Tellig describes the sound of the Cambridge 640c as "a tad hard". Not to say the Cambridge is a bad player, because it certainly is not. Perhaps, you are putting equipment with the Outlaw pieces that are just a tad bright for your listening preferences. As a 950/755 owner, I can say that the Outlaw combo is very neutral and will generally only pass along what it is fed. Good luck with your hunt for audiophile nirvana!
