I am setting up my first HT. Running Paradigm Monitor 9's with matching center and sub. I was looking a good AVR to go with for $800 or less. I happened upon a deal at the local BB on a new Marantz SR 7005 for $699. I know this unit was built in late 2010. I have a couple of weeks to return it, if need be. I am concerned about buying what is essentially 4yr old technology. The unit comes with a full warranty. I was looking at the Onkyo NR818, the Pioneer SC-61 and the Denon 3113ci. All see to be reviewed pretty well. Any thoughts on what would be the best course of action? I listen to music about 30% of the time, but also want something that makes TV (Panasonic VT50 plasma) and movies enjoyable.
