The item that sets the AVR-2112CI apart/ahead IMO is Audyssey MultEQ XT. I'm not sure you'd audibly notice the extra 20w per channel on the 6005. Pre-outs are nice on the two Marantz's if you should ever think about upgrading to a seperate amplifier however.
Thanks guys. Sorry for not responding sooner but I was swamped at work the past couple of month and never got to check back in. Do you think the video processing in the Marantz is superior or are they about equal? Thanks again
