I'm a bit indecisive on these two models. I have heard good reviews on both the Yamaha and the Onkyo, however, I don't know which one to get. I currently have a Kenwood VR-6070 which I bought without doing any research and have been throughly disappointed. My biggest complaint, with this model, has been with its poor decoding of DTS. There seems to be adrop-off in sound when DTS is engaged. I am currently using Polk Audio speaker and Bi-polar speakers as my surrounds. Any advise will be appreciated.
