I have the original 1980's CD release of this, as well as the 2003 CD, which is just the Redbook layer of the SACD. The 2003 has a much fuller sound than the original CD. What you're describing is how I would describe the sound of the original CD, thin and shrill. That being said, these are the only versions I've heard. Maybe someone who's heard another CD version, or even the LP can chime in.
