NPR had an interesting segment on Science Friday this past week titled "Why Vinyl Sounds Better Than CD, or Not" which you can listen to here: NPR Talk of the Nation

One of the experts they interviewed, Sean Olive, speaks briefly about the loudspeaker design research he has conducted in Canada at the NRC facilities. I believe these are the same ones used by Axiom. Anyway, both experts concluded that CD is the superior format. An interesting 25 minute discussion though.
