Looking to replace my Yamaha dsp 757SE after 5 years. I run a projector as well as plasma so love the Yamaha as it has 2 HDMI output so I could get rid of my HDMI switcher (fewer cables one more free plug!!) but the Yamaha doesn't have the ProLogicIIz height program. I run the PrologicIIx off my current amp and love it. What do I do? The Yamaha is 399 and onkyo as low as 329. I know both would be a step up from my current amp but can't decide what to do. All suggestions welcome.
