I agree with the comments of "brightness" at the limits of volume... which is what I experienced watching Jurassic Park. His comments of using an efficient speaker make sense, based on the 2-channel power ratings... but I listened to Klipsch and Paradigm (both very efficient speakers)... but they didn't sound as good to me as the Rockets so instead of choosing speakers that work with my receiver, I'll need to choose a receiver that works with my speakers. Looks like I'll be spending this weekend trying the 1070 again with the 8ohm setting and will be comparing the Yamaha and the Outlaw with the SPL meter to see what the differences are - as well as my ears for clarity, image, soundstage, etc.
