I have their brand new 8x8 hdmi (18gbps; hdcp 2.2, etc) matrix for my own personal system but it is not installed yet. I plan on integrating it into my Elan system and AVPro developed the elan driver themselves. So I don't have any experience to offer on this matrix, but my expectations are high as it will be an all 4k system when it is finished

I've used some of the 18g splitters with EDID management and also buy my Celerity optical hdmi solutions from them.

Great tech support and great service if you ever have a problem.
