You may want to hold out for the NR818 which is about to be released from Onkyo. It's the replacement for the NR809, and provides Audyssey XT32/SubEQ, which is a huge advancement over the 809. I believe the amplifier stage in the 818 is also of a monoblock design which is another improvement to note.
I'm a KEF fan, but to be honest, I've only really owned their Reference line of speakers, which are nearly all 4 ohm speakers, and a nearly flat, resistive load, so they are very efficient, easy to drive even with an AV receiver, and tend to have a sensitivity in the 90-92dB range, at 1W/m. I respect Klipsch as well, I just don't find them as desireable to my ear.
