Why is 2 Channel better than multi-channel?

I would agree with sean. When a two channel system is set up correctly, the soundstage needs NO speaker in the middle. The problem is that seldom do people take the time to learn and execute proper speaker placement, or people build the system without regards to the room volume and dimensions (Too big of speakers in too small of room with a rack of equipment or worse a big T.V. in the middle). This will lead to disapointment of two channel. It has taken years to get two channel right,dedicated circits, wires not crossing all over the place, dampening materials on walls,correct speaker width and distance from sweet spot, speaker in proper placement in relationship to room boundies, correct toe-in of speakers, amp stands and stereo stand dampend (which is major important with tubes). With all this done, critical listening can be done to really bring a system to life. You will hear the differance in tubes, wires and anything else you do to the system. Once you get to this point you will not want to add more because you will get less, less enjoyment! Keep it simple.
It seems that people try to improve sound by making things more complicated. I have tried this approach and have been disappointed. More speakers, bigger subwoofers, The typical american approach. Now I keep it simple and the rewards have been great
