Jmone (Nathan),
It depends on which PSB series you are talking about. During many yeas as an editor of Canadian AV magazines, I did double-blind listening comparisons at Canada's National Research Council with PSB, Axiom, Paradigm, Energy, Mirage and many other brands.
Generally speaking, Axiom's models are more neutral and transparent than PSB's Image series. The Axioms are comparable to the PSB Stratus series. The Axiom M60ti or M80ti, for example, would be comparable to the PSB Stratus Gold or Stratus Silver, and a lot less costly.
Regards,
