Joel:

I will admot that I do not fully understand the EDID set6upwith the audio portion of the RadianceXE as I find the menu ssettings / structure very confusing...that said, and I may change my mind, I am thinking of putting the HD621 in front of the RadianceXE because of (i) the number and (ii) the prolonged duration of the audio issues that are appearing on the Lumagen forum...quite frnkly, these concern / scare me...

All that said, a WIKI or posting from a helpful individual explaining the EDID setting within the RadianceXE could / would get me to reconsider...are you volunteering...
