Finally got around to setting up the 607 last night (been in the box since Friday). I have an older Toshiba RPTV (80H57) which only supports 1080i and NO HDMI ports. So, I have some interesting juggling to do with this reciever.
Hooked up to my old receiver were standard DVD player, the Xbox 360, and a DirecTV HD-DVR unit. All via Component. The DVD player went directly to the TV as the second component "in" on my set has been ISF calibrated specifically for 480p. That means, unless I want to go in and recalibrate that input, I have one Component in on the TV to work with here (it's calibrated for 1080i).
SO, now I have my DTV DVR going to the receiver (component), my PS3 (component to receiver for video, HDMI to receiver for sound) and I have to let my 360 cables hang in the back as there are only two component INPUTS on the receiver.
Ran the Audessy setup routine and it did a decent enough job with my SVS SCS-01 speakers and sub. Although, I dialed up the crossovers for the front and center a bit (Audessy had them at 60) and added a bit more punch to my sub. My room is not an ideal environment as it is my main living room with cathedral ceilings and a loft overlooking. But, the sound was great and I could definitly tell the difference in the HD tracks over standard Dolby Digital. I had a Yamaha HTR 5040 (think that's it) which sounded great but had no HDMI or HD audio codec support. This gives me that functionality and sounds great, to boot.
My only issue is that to play games on the 360, I have to unplug the PS3 components and plug in the 360's. Not a huge deal, but annoying right now.
I plan on finishing the basement this year and having a dedicated theater room. I also will be selling off the old Toshiba set and getting a new Plasma or LCD so that I have HDMI connectivity throughout (and eliminate the need to unplug/plug component connections)
So far the receiver was a good purchase and upgrade for me. It future proofs me with 5 HDMI inputs.
