IT was recorded using some special processing in its day that gives it that sound. A few others back then as well.
"It is the first album ever to use the audio technology QSound."
Madonna's soundstage
I hadn't listed to her Immaculate Collection in a while. I have changed some components since the last time and was blown away at the soundstage of this album! I normally get a decent appreciation for my system's soundstage. My system is in a large asymmetrical space and I am unsure if I can ever achieve what can be in a dedicated listening room. When I played this album today there were sounds coming from 5 feet beyond the speakers and my listening triangle is only 9 feet! It was on multiple songs and was so cool! I was curious if this album is a standout for others as well.
