I currently have a Marantz SR6400 receiver. I was happy with it as it suited my needs thus far. I recently got an Epson 5020UB projector and I have noticed that when I watch Digital Cable and PS3 Blu-rays, I see some really bad audio sync issues. It seems my new projector has more video processing latency than my old setup. My SR6400 does not seem to have any delay settings. Can anyone advise a suitable replacement? I have 5.1 speakers but a 7.1 receiver would be good for a speaker upgrade path down the road. I need serial RS-232 control for my automation system. Finally HDMI inputs/switching would be nice, though it must support HDMI1.4 for my 3D projector to work well. There's a lot of receivers and I'm not really up on what's hot and such in that area. Thank you.
