That's a good point. When I got my flagship DVD player that was "tuned" by Air Studios, and listened to its analog outputs vs. the digital connection to my receiver I was blown away in the difference in sound.
Turns out Air's tuning was mostly about running the RCA jacks at about -8 dBV, instead of the more usual -10 for single-ended, line level. I enabled the volume trim settings, and its unity position was actually correct. So with the volume control off (the default) it was running the outputs hot. Louder always sounds better.
The speed at which my receiver reacquires an HDMI sync is too slow for any quick flipping between inputs. With the extra Voltage disabled, and the 3 second delay between switches, I can no longer tell a difference.
