$9000 range? I wouldn't even think of going that high without considering Paradigm Signature and PSB Synchrony. I definitely suggest auditioning them. The Synchrony One needs a fairly hefty amp and from the specs an Onkyo M-282 (125 watts into 6 ohms) look sort of marginal for it if you play loud. But you could get a Bryston 4B or something and still save money.

Your amplifier should do OK for a Paradigm Signature S8 or S6.
