When I watch standard-def content on my hi-def display, I don't map each source pixel to each display pixel, otherwise I would end up using a 480x720 grid of pixels in the middle of my 1080x1920 display whenever I watch a DVD. Instead, all sources (480, 720, etc) get scaled to my HDTV.
Likewise, I don't map the number of discrete channels in the source material to the exact same number of speakers in my set-up (each channel sent to one-and-only-one speaker). Instead, everything gets scaled to my speaker layout. When listening to 2-channel material, anything that phantom imaged at the centre of the soundstage now comes from my centre speaker. In real life the human voice is not produced as a dual-mono, comb-filtering phantom image; I don't see why I should re-produce it that way at home. In real life when listening to live music, ambient information doesn't all come from the same direction as the soundstage, instead it comes from around me. So at home, I would rather re-route recorded ambience to the speakers that are around me rather than restricting it to the speakers in front of me (which sounds unnatural to me).
It's never mattered to me whether I had 3 speakers or 5 speakers or 7 speakers; all sources, irrespective of number of channels, gets scaled (up or down) to the number of speakers in my current layout.
