Thing is, you're not doing traditional bi-amping, as they call it, since removing the bars from the back of the speakers does not remove the internal passive crossover. So while their explanation is correct, it's not what their receivers do.
But hey, it hurts nothing to do it the way you do, other than the lack of 7.1.
Just trying to learn, so hang with me. My speaker manual says how to Bi-amp, and how to Bi-wire both, and my Studio 60's can be Bi-amped according to the manual. I would agree that it would not make any real difference if I was just running a second set of wires. I am pretty sure that when you configure the Denon for Bi-amp, it only sends the low freq stuff out of those speaker terminals.
I guess if you are correct, then it is just a useless function they have built into this receiver.
