I doubt if too many people have ever heard the S8's let alone A/B'ing them with the M80s. I've visited a couple of Paradigm dealers and they usually seem to stock only the Monitor and Studio lines, which are the most often compared to the Axioms, and the Signature line is special order. The M80s, by many accounts including my own, sound similar to the Studio 100s so if you are able to hear the S8's and the Studio 100's together, I would suggest that any differences/similarities might similarly apply to the M80s in place of the Studio 100s.
