A:Answer Let me correct my first reply to confirm this amp DOES have the auto-pwr feature - yay! When the cable or TV's HDMI go live, the amp can be set to come on and auto-set itself to that HDMI input (but its audio takes several seconds to start).
I'm noticing the audio swing back-forth between loud and quiet, such as when a movie goes between loud action scenes and whispering dialogues, seems to leave the quiet passages hard to hear. Today I'm doing the microphone tuning for speakers, hoping might help. The other Sony amp seemed to handle the "quiet" audio much better, but, could also have been the media source was simply mixed better when I was using the Sony. Will see.
