Hi, Nick.
There are many articles on this bi-amping thing, but basically all of them end with "If you can do it, then try it, it may bring improvement to the sound, soundstage, transparency, etc."
So that's what I am thinking, if it'll work, great, but if sound is the same then I can rest easy knowing that I did all I could in that link of my home theater P-)
Thanks, everyone, for your input.
If you have anything else to add on the "suitable amplifier power range" or "maximum input power", post it here.
Cheers,
