Wasn't sure whether to post this in music or not, since it's not specific to any particular music - it's more a technological issue, but who here agrees with the following observation? And this is not intended to start a flame thread over 2-channel vs. 5.1, it's just what I've come to a conclusion about regarding the proper reproduction of audio... Music isn't heard acoustically-correct with only two speakers, surround channels are necessary to provide "natural fidelity". I've been doing a lot of listening to CD's in DPLII lately (and true 5.1 sources as well) in a sweet spot surrounded by 4 Optimus LX-5's with sub and center channel and I'm of the opinion that since we live in a 3D world, in a 360-sound field, then listening to music confined to two front speakers just isn't natural. To fully experience close-to-true live ambience as well as the artist's emotional intent of his music you have to have that surround ambience that fully envelops the listener, because in any musical setting whether it be studio or stage, live music is going to be reflected from the room boundaries - two speakers just can't reproduce that natural surround/ambience dimensionality properly. Not only do you need left & right, but you need front & back acoustics to approach a sense of “live musicians playing in your room”. A stereo mix, no matter how well-done, is always going to be missing some crucial spacial element that a surround mix will reveal, for the betterment of the musical experience. So, if iPod's can ever reproduce CD-quality 5.1 in headphones, maybe surround will prosper with and be appreciated by the masses. Your thoughts?
