I'm buying a new receiver for my son's room, and need help deciding. I live overseas and am buying at my AAFES, so not a lot to choose from. He will be running Yamaha NS-555 fronts, Yamaha NS-C444 center, Yamaha NS-333 surrounds and backs, and an old Cerwin Vega sub. His room is about 10' X 15' and usually splits time between video games and movies. The two best receivers in my price range at the BX are a Pioneer VSX-LX50 for $600 and a Yamaha RX-V1700 for $597. I know I could get it cheaper on line but shipping is usually really high. Any input would be greatly appreciated.
