Though I am not an authority in this matter, let me put it this way. Biamping drives two pairs of wire from two different Amp source to feed the speaker (of course the speaker has to support biamping - two pairs of input). The Amp when set the right way drives the lower frequencies through the woofer and the higher frequencies through tweeter. If you put the single pair of wire the speaker itself do the separation of high and low freq. The difference here I guess, is the separation process done by Amp may be better than that of speakers doing it.
Now the difference in output between biamping and additional surrounds may be thin but you may get a better sound stage for additional surrounds, that's my guess. But biamp surely gives results according to many in this forum.
Guyz please correct me if I have said anything wrong
What you said about 5.1 and 7.1 is correct. But make sure the quality of sound is same on both models. You can find other threads in which people agree or disagree on the sound quality similarity of both. Other than this I guess 1911 has a video upscaling which 1611 doesn't have. There should still be some more feature differences to distinctly place 1911 above 1611 as part of the product strategy but may not make much appealing to all.
