there is a new model to replace the RXV750. The nice thing with the 1500 is you can power a second zone - like speakers in the master or on the deck - without needing a separate amp. DONT USE "B" on the reciever. The 750 will give you zone 2 output but you'll need an amp. It will give you the YPAO (room correction mic" though. If you are going to buy new speakers too, you may be able to get some type of discount - maybe 10 or 15% if you buy it all at once.

what do you intend for zone 2. that may help shed some light on exactly what model fits your bill
