Jerry. I have a Radiance which has virtual HDMI inputs. That means you can switch external to the Radiance but have different virtual sources (i.e. configuration memories) which all use the same physical HDMI input. Or, I could switch in the Radiance. With the Meridian solution (PCM over HDMI only) I don't need the HD621's HDMI v1.3 switching and the v1.1 (or is it v1.2?) switching in the Radiance will do the job.

I also want to know if the HD621 has six receiver chips (HDMI sinks) (i.e. one per input) or just the one. If six, the HDMI handshake will be persistent even when the source is not selected. If one, the HD621 is simply a switch and there will be an annoying delay whenever source switching takes place. The Radiance has six receiver chips.

At the moment, I switch in the Radiance and HDMI output #2 (a constant audio-only signal on a blank 1080i60 video carrier) feeds my modified CLUX11SA.
