I would like some suggestions on a small cheap but quality bookself to replce my ML Aerius, since I now have a beautiful 3 month old daughter and I know she would just love to climb and pay on m ML Aerius so I plan on boxing them up for 2-3 years as I did with my son, anyways I am looking to spend 2-3 hundred I like the paradigm atom's , but I have read that the Axiom m3's out perform them is this true? Or is the an even better speaker out there in my price range, my amp is an Audio Refinement The Complete, sony cd player with MSB Link 3 Nordost wires, Thanks for any opions,Nick
