You can get much better receivers than those listed if you have $600-$700 to spend. Do some searches on yahoo.com, onecall.com, shopzilla.com, jr.com, ubid.com, dakmart.com in that price range and you'll be surprised what you can buy for that figure. Some of the high end Onkyo's with THX certification are steals right now. HK is powerful stuff, and the power is underrated, but they are pricey. jr.com usually has decent deals on them.
