Zilla, your AU24 are only 8 hours old?! I think 200-300 hours is more like it before you get the full benefit and are able to hear what they should truly sound like.
I hope you allow enough break in time for all your cables. Depending on the cable their sound can change dramatically during burn in. Some are very subtle, but I have a pair of Ridge Street Audio Poiema that kept doing a crazy chameleon dance on me the first week. It was almost as if Kirstin Dunst morphed into Janet Jackson, then Rosie O'Donnell, before finally settling on Nicole Kidman. A really weird and wacky modulation of sonic shifts!
