So after having owned a half dozen Denon’s here’s my amateur comparisons between the Emotiva MC1 and Denon x6700h.
Denon, has MultiEQ X (for $199.99 if you’re so inclined and I’ve found it highly useful but even so if that’s out of your budget the $19.99 EQ editor app is also phenomenal when used in conjunction with Ratbuddy) it has 7 HDMI 2.0B inputs and one HDMI 2.1 input, the GUI is streamlined and easy to navigate. Constant firmware updates. When I power it on, it works. All the time.
Emotiva, has Emo Q which is a single point measurement Room PEQ system where mounting the mic isn’t an option and they recommend you hold it in your hand. Has 6 HDMI 2.0b inputs and an e-ARC output (which is what I used). E-ARC output only works when you least expect it. No firmware updates since it’s release. Likes to get stuck in a boot loop every few days. Doesn’t work when I power it on every time. Is the worlds most uneconomical paper weight at $999.
