I alresdy had the 2000i,400,rt35's,450sub with my 3802.I sold them a year ago,now Klipsch rf7's,rc7,rs7's,rsw15,NO comparison,not even comparable.Uhhh...yeah, I would sure hope so. The Klipsch rig you are currently running costs about 5 times the Polk rig you originally had.
The Klipsch Reference Series IS awesome - I recommend it often - but you DO get what you pay for.
