2-channel vs 3-channel/5channel

I will be trying it out in the future. I have all the necessary ingredients. Arcam AVR600 / 805N for the back channels. I just don't have the center - which I might not need.

To answer your question, yes, you will get a lot from the addition of one or several channels. Adding channels gives the potential for improved sound, but...that all depends on execution.

If you get good imaging in stereo, you may not need a center channel for HT. We use the same 6.2 setup for music and HT, although I rarely turn on the amps for the two rear channels, so we really use a 4.2 setup, and it tracks dialog very well. I removed the center channel, because it didn't seem to contribute to the sonic experience.
