In my experience there are no "stereo system flaws" when playing 2 channel music, and to describe them as "deep" also seems an exaggeration. In terms of UMIK measurements and listening experience I really don't see/experience any "flaws" in a stereo system playing back 2 channel music. In my experience it creates a wide & smooth soundstage that extends between the speakers and even out beyond the sides of the speakers, the speakers just disappear, it doesn't even sound like the music is coming from the point source of the speakers. Also there is no "real event" when it comes to music, it's a fabrication put together by the artist and engineers, so it's more an "imagined event" that is created by the artist & engineers through 2-channel, it's an artistic (re)creation.
