I am in a similar boat. I own the 673 and its great but if you want to play the same source out of both zones at the same time you will need to get the 773. Also the 773 has out to hook up a external amp. I owned the model up from the 1222 but returned it due to defects. It sounded great otherwise. Lots of people like the Denon on here, it has the best correction software but it doesn't have speaker outs. I would buy the 673 again in a heart beat, it sounds great and to my hears I liked it more than the Pioneers. If you wait a few days A4L will have Yamaha stuff, they might have a 1020 priced like a new 673? never know.
