Great chart. That puts it into perspective!

Joe, are there any HDMI switchers out there? As far as I can tell you have one HDMI 2.0 source, the Oppo. So could you run the others via a switch then into the Oppo and then the Oppo audio into the HD621?

I believe HDMI will only allow you to carry high res audio if there is at least a 720p/1080i signal associated with it - even if it's blank.

Best regards,
