I have the Yamaha RV-X 1700 old receiver. HDMI 1.2. Now it does not decode the new True HD and Master HD audio Soundtracks. Also i run Crown Amps for my fronts and center which need certain amount of amps from receiver from the RCA outputs. 2 volts i believe mine only outputs 1 volt. I love my receiver and it sounds great. But my question is would i benefit from a newer receiver with the up to date HDMI standards and just more up to date in general?
