I recently got a 605 myself and I am VERY happy with it.
Everything works as advertised. Not one issue. Setup was easy and fun, the Audessy worked perfectly, though it turned the "double bass" on, unless that is the default. I didn't need that on, so I shut it off.
It doesn't run "hot". It seems rather normal to me temp wise...no where near as hot as my 360...and they are on opposite ends of my TV stand, so there is no issue for anything there.
Low volumes come through nice and clear. For late night viewing, I turn on "late night" and it lowers the bass while keeping the sound clear and understandable. I like this feature alot.
I have lowly Polks from 1998/1999 hooked up to it (RTi600 line fronts and similar line center and rears...nothing major just avg/below avg speakers-along with a new X-sub) and they sound better than they ever did...good enough so the Axioms I wanted aren't eating away at the part of my brain that tells me to buy BUY
BUY!
I run one HDMI cable from my 605 to my 56" Sammy DLP and everything comes though nicely. I have a SA 8300HD-DVR cable box hooked up via HDMI, along with an Oppo 970 via HDI and my Xbox 360 via component and all work and sound great.
I got mine for under $500 delivered to my door, and that included a 5 year plan from CC also. So far, the value is great. One of the best purchases I ever made.
When I get the PS3, my little playland will be complete.
