Kind of defeats the purpose of having an exotic system(?)....if you want the soundstage to mimic the effect of listening to a 1960s AM radio station. Don't 'ya think? ;(
I, personally, never minded the spatiality of wide stereo; because I hear it as a way of being able to focus on somebody's individual PLAYING when stereo tracks were mixed as lop-sidedly as a lot of stuff in the '60s was (usually: with bass, drums, and rhythm on the left, vocals and lead guitar on the right). The "neck chills factor", to me anyway, is: when the separation is so extreme to the point of being isolated that it's like a karaoke effect, I just imagine it's like a "you are there"/time travel-trip back to being in the actual recording session booth with whatever legend made this music at THAT moment.
I never got that sense from a mono recording at all. They sound too "dry" and with everything coming at you at once; like it's just the commodified production rather than revealing insight into the musicianship itself.
