I have a pair of Atoms sitting on the bar while I figure out what to do with them. I liked them a lot until I had a chance to do some serious A/B testing with the M2s... Atoms are real nice speakers and probably *are* better standalone speakers than the M2s, but I still think the Axioms are comfortably ahead in terms of accuracy and clarity.
