HBrandt-
How did your Phantom vs. Real Center Channel Test go?
I have an EAD TheaterMaster as well, and just had to send my Talon Falcon C center channel speaker back to the factory to get it shielded. I really miss it, as my EAD doesn't seem to like being setup without a center when Dolby Digital or DTS signals are decoded. It gets very quiet compared to the same material in Down-mixed 'Digital Stereo', 2-chnl Stereo or Matrix modes, requiring a big change in volume between modes. And - before you ask - it IS sending the center information to the L/R mains, as I can hear all the dialog.
In all other modes, the center image provided by the EAD is just terrific - even way off-axis - enough so that I too would consider doing without a CC if it weren't for the fact that this configuration doesn't seem to work great with DD 5.1 signals as described. As it is, I want my center channel back NOW!
Maybe I don't have my EAD setup for Phantom mode correctly? Not sure - but it won't stay in this configuration much longer, anyway ....
BTW - I REALLY like the TheaterMaster. It's kinda daunting to learn the menu/interface, but the results are truly worth it.
