If you’ve ever heard music played through a surround sound system and think that it sounds realistic or even pleasant, then by all means go ahead and add more speakers to your system.
@aewarren , Could it have been that you heard some awful multichannel setup, wrong codec, etc on some cheap barrel bottom receiver (stereo equivalent of a 10 dollar bluetooth boombox)?
Here’s an excerpt from a guy who sells high end purist stereo equipment that many guys around here own. I mean, it is this guy’s livelihood, but, at the least he’s being honest about what multichannel audio sounds like.
"and you just close your eyes and you’ve never heard a soundstage like this. I don’t particularly like listening to it because when i go back to my li’l stereo system or my big 2 channel stereo system, I am let down. Yes, there is a soundstage, the speakers disappear, all that magic happens, but, man...you hear that in a good surround system and it will blow your hair back, it’s spectacular"

The guys who have such rigs, listen to it on a daily basis aren’t lying when they say they are let down by whatever high end stereo sounds like (after listening in multichannel for a bit)......There are several high end audio manufacturers who sell purist stereo audiophile equipment, but, actually do their personal listening in multichannel audio for their own personal listening pleasure.
(Yeah, it costs more...because of course, more speakers and pertinent gear costs more! Bigger room costs more to treat, a bigger house costs more, etc... But, that’s the inherent cost of the next level experience, i.e., when you turn it up a notch).
