Stay with the Yamaha!! The amp section is far superior. The DSP modes are fun to play with but sonically degradeing. Has plenty of output and inputs, but lacks the component switching abilities of some of the newer units on the scene.You can tweak the settings of the dsp-amp1 to match thx standards. Also with a simple speaker selector you can set your amp up to use dipole and standard speakers for rear effect on movies and music. A=dipole, B=standard, A+B= both. The amp can easily handle a two ohm load.(Mine has ran that way for over 6 months when I purchased new.) Good luck in your decision makeing, but for me the choice is simple.
