My rig is a 2-channel/HT combo, but the 2-channel sources run a detour around the multi-channel gear. When I had a large SD RPTV with my center atop it, that illusion happened constantly when listening to stereo sources. Now, with a plasma, and center mounted beneath the TV on a stand, the illusion is rarer. I think this is due to the height of the center image provided by my Ohm Walsh 2000s. Most vocalists appear to be about 5'6" tall, about where my center used to be, but about 3 to 4 feet higher than where it is now. A visual disconnect.
FWIW, I did try my system with a phantom center setting, but on film soundtracks, the center just lacked some oomph that it has when I installed the center channel speaker.
