I have now had the MC-700 for about 6 weeks. It works well, except when moving from the 4K HDMI outputs to the standard HDMI HD outputs, as in from 4K Roku to Comcast TV. It's connected to an LG 65B6P OLED TV. Sometimes it takes up to 10 seconds or so, and a few times the audio won't come on and I've had to shut the unit off and reboot it on again. Then twice when watching a 1080i (comcast cable) TV program, the audio format changed when they went to commercial, changed again for a local commercial, and I unexpectedly lost audio all together. Reboot again! I got Emotiva to have Logitech add their remote codes. I can use my Logitech 650 remote for some things with it, but I'm still working on training it to be able to switch from 1080 to 4k mode. Haven't succeeded yet, but hope springs eternal. I'm told there is a firmware update coming, Bring it on!! When you do, make it so we can see (onscreen) the volume control bar in both HDMI modes! The MC-700 can use some tweaking. Audio quality is very nice, way over and above any higher priced competition.
