HAving the un-opened box sitting on the floor mocking me was too much to take.
Setup was so fast/easy (I'm coming from separates w/out HDMI) I had my speakers and PS3 up and running in minutes to test it out.
For the past few days I've dropped down in speaker size across my front stage. gone are the Klipsch RF3 fronts and RC3 Center in favor of Orb Audio Mod2s (to match the existing surrounds due to apt/ size/space), this was prepare my ears for any 'downgrade' that may occur with switching to the onkyo while still using the same speakers.
First impressions: Wow! As mentioned above I'm coming from separates (Outlaw 990/770, which I've had since they were both released) and I'm blown away at the power/clarity of the 608, given my room size I'd be hard pressed to tell the difference. There is no sign of downgrading at all, the Orbs sound just as good (but obviously a much different sound than the Klipschs.
Video-wise my image appears darker but then again my set was calibrated via direct connections via HDMI (no Receiver pass-thru).
The Fan is quiet but I'm leaving the unit on for a while to stress it. so far it's cool to the touch (and nowhere near as nuclear as my old amp

The audio switching/clicking is a bit on the annoying side but I'll get over it.
Handshaking via HDMI is just as bad as it ever was (Samsung LED DLP) so nothing new there.
DTS-HD when selected via BD doesnt' appear to have a display icon, it only shows up as DTS?
I love the onscreen GUI (and love the fact it comes up via any input, I was still having to hook up a component cable just to see the Outlaw GUI and would have to swap inputs just to do so); seems very straight forward.
Remote seems ghetto =D
So far so good! More to follow!
