Sanjay- But why don't they do something *real* to differentiate it?

Like fix the double bass problems for the 5.1 analog inputs run full range, or the 2 channel analog bypass when the mains are set to small? Or at least give a menu config item to toggle that behavior?

Or, be able to select the sub crossover individually between the surrounds and the rears?

Or, copper shield the analog vs digital, or video vs analog components inside, or just the whole chassis...

To me, you know what the biggest difference is? The faceplate...
