I game on a PS3 and have always used external devices with DH like the TB DSS and Astro A50's. The thing is, most (if not all) of these common DH external processors can only accept DD 5.1 through optical as the max resolution.
I recently found out some AVRs include Dolby Headphone. This means I could now run HDMI and not be limited to the PS3 DD5.1 optical limit. Does this mean Dolby Headphone would perform better with a 7.1 HDMI source?
