From what I understand, the Paradigm Studio line of speakers sound very similar to Axiom speakers. The biggest difference is the price. Your father could actually save a lot of money by selling his Paradigms and switching to M60s in the front. But I digress...
Alan, one of the moderators here and Axioms resident audio expert, has said on more than one occasion that the Studio 60 sounds very similar to the M60ti. Because I know that the QS8 is a perfect match for the M60ti, it should also work fabulously with your dad's Studio 60s.
