Q-Sound CD

What do you think about CD in Q-Sound?

Strange effects with sound coming from sides etc.
A little artificial sounding, but nice for effects in non acoustic music. I just know a Sting recordings and as far as I remember a Roger Waters that makes use of it. Would be interesting to hear a classical recording with Q-sound.

To hear it properly you need an exact speaker/listener positioning and also proper phase coherence of components I guess.
