I just pre-ordered an Onkyo 608 and will probably be leaning towards two PL-200 Subs and Polk audio for the rest of the setup. I haven't purchased the subs nor the other speakers yet, still shopping around. My old setup was a Sony receiver with all Sony speakers, so this is a big jump. For the price and sound, Polk Audio is good for me, unless I find something around the same price range. Man didn't think audio stuff can get so expensive when you want a good setup.
