Oh, and too. The video display is not analogous to an amplifier. It's audio realm analog would be the speakers. No one is arguing that one pair of speakers sounds the same as another. Speakers are not a technology that has matured to the point where they can reproduce a signal with undetectable differences from the input.

I will go so far as to say, a well designed blu-ray player with no post-processing will output a signal from its HDMI port that is indistinguishable from another model meeting the same criteria. As long as the cable to the next input is within the limits of its output drive.
