My question is this has anyone owned or auditioned these speakers (Paradigm) and then purchased the Axiom's?



Yes...many times. Axioms are generally compared to Paradigms elite "reference" line of speakers. Which as I'm sure you're aware, cost a LOT more than the comparable Axioms.

In reply to:

I was leaning towards the M80ti mains, Vp150 Center and M3ti rears.



For your room, I'd suggest the M60ti mains, VP150 center, and QS8 surrounds. The QS surrounds will timbre match the center and mains better. The M3ti is Axiom's unofficial "bedroom" speaker. (meaning, it's the preferred speaker for a small 2 channel system in a bedroom) The QS8's are routinely praised as being "the best surround speaker I've ever heard!" (Myself included)

Bottom line, get the Axioms, and don't even worry about those Paradigms.
