So I took a search in YouTube, found one and OMG. The UHA-4's crossfeed does help to centre the vocals a bit but it's quite subtle. Most apparent at the point of switching it on then off. Good song, but it's not something I'm in to right now. Probably in another time perhaps? Thanks lee.
Okay then it really depends on the song then. It's just the modern songs seem to be made for headphones and older songs seems more for speakers. Is this a correct assumption?
Well it really depends. Just the tracks back then were mastered completely differently. Was their own flavor back then. Maybe I can drop you the actual file to demo. Its much more noticeable on a true file than one uploaded to youtube ;).
