For movies, sure. For music, I don't think they have the kinks worked out yet, particularly on the software side. As for hardware, most of us have our systems set up optimally for movies, not for music. Generally, I prefer SACD in stereo, not multichannel, and if I listen in multichannel, it's better with the center channel off and the signal summed...</td></tr></table>
I've heard so much pro and con on this! Until I actually get my own multichannel setup I guess I should withhold judgement.
On the face of it, it seems obvious that an actual center channel should be superior to a phantom center that is created in your mind by summing: the stereo image should be wider with an actual center and won't collapse when you move off center out of the "sweet spot", the instruments in the middle (winds and brass) should be more realistic (talking symphonic music here) since they're mainly coming from their own speaker, etc, etc. But enough people like you prefer otherwise to make me wonder.
Maybe it is the software. But I have heard and read persuasive opinions that even stereo CD's are greatly improved in DPL II mode with a center channel.
Also, it's worth noting that when stereo was being cooked up at Bell Labs in the '30s that it included a center channel for the reasons I stated above. Two channel seems to have resulted from the limitations of the playback medium then available to consumers, i.e, the vinyl record and needle pickup. I guess they couldn't get three channels to work with a single pickup.
I guess I'll just have to build myself a center channel speaker, get another amp channel & a pre/pro, and find out for myself!</font>
