I have the 7704 AVR and it's a great piece of kit. I am sure this takes it to the next level.
i hate and love this place all at the same time..I finally have my divorce threatened PJ paid off....and now I want another upgrade from my x7200wacmon!! haha
Front Wide speaker capability is brought back as well.
If the Emotiva RMC-1 actually gets released soon, at maybe a similar price* the comparison to the 8805 should be really interesting. One notable difference could be support for an HDMI 2.1 upgrade by Marantz where the Emotiva doesn't appear to offer that.(*MSRP is $500 more for the RMC-1 but I expect the 8805 to be discounted by AVS and elsewhere so there could be a bigger disparity.)
