I personally went with the 674. I was able to listen to it at CircuitCity. The only difference I could see on paper is that the Denon is rated 5 watts higher. It appears they are pretty much identical in every other area. I guess whichever sounds/looks best to you is the better option IMO.
About the PS3 related issues. I just got my PS3 today and everything seems to be working fine so far. I don't have a 1080p TV but I am using HDMI. This has brought up an interesting situation though. When I use my 360 with Component IN to the receiver and Component OUT to the TV. It looks fantastic. But when I use Component IN and HDMI out, I get wiggly lines across the screen(very noticible with text). But I am using HDMI IN and OUT with the PS3 and it doesn't happen. So my best guess is that something is happening in the conversion of the analog to digital process that is causing this. Is anyone else experiencing similar issues? Does this sound like my receiver may be defective or maybe needs a firmware update?
Thanks in advance,
