I've come across two opinions on the subject of the center channel: 1.) The center speaker is the most important, and you should build your entire system around it. Not having one is not an option. 2.) The center speaker is only important if you have a wide soundstage, and you're actually better off without one if your mains aren't spaced that far apart. I've caught upgrade fever, and I'm torn between replacing my really crappy center speaker with a good one, or eliminating the center speaker altogether and replacing my average mains with two good ones. My HT is in a small room, so I have a very small soundstage, with my mains only around 4 feet apart. I'm on a limited budget, so which option would give me the biggest bang for the buck?
