Recent Stereo Upgrade?

Have any of you installed a new stereo in your boat recently?  I need to replace the stereo in the salon and cockpit on the boat. I am going to switch from a 110v ac to 12v dc since I think it will be more efficient than running an AC unit through the inverter.  I am leaning toward a Fusion RA770 Receiver that will allow me to control multiple zones (salon & cockpit) separately.  It also has its own wifi connection so that I can connect iphones instead of going through Blue Tooth (better signal so that I don't lose sound quality).  It will allow me to run the DVD player for watching TV, then I can also add an additional amplifier and subwoofer. 

Anyone have any opinions?
