All recordings sound different one from another so there is no set amount of spaciousness on every LP you play due to colorations. You only hear spaciousness if it was part of the original recording. I for one don't believe that LPs tack on artificial spaciousness. What LPs do allow you to hear quite clearly are the added studio effects such as reverb. Again, every recording sounds different which stands in stark contrast to consistent colorations that you will hear no matter what the recording.
Again, whether you realize it or not, you are arguing based on specifications and not personal experience. Having a friend with a turntable/arm/cartridge combo that you can't remember doesn't count for experience in having a good quality LP system at home and listening to it regularly. That would be experience that would serve as a reference for your point of view. For now, you are starting to remind me of another member here who keeps posting the same things over and over and over and over again.
Well at least we have that in common.
