Dear JJ: Yes it is possible that some come with different phase/polarity.
+++++ " some of my records have a very open sound stage while others seem very compressed. This variance occurs with records of the same production year and condition.... " +++++
here you have to remember that each record pass for a different recording session where the engginers make changes according what they like or the producer want and these are reasons for the differences i playback.
Now, with a " dipole " speaker like the one you own the phase subject is almost dramatic: yesterday I was at my friend's Guillermo place who owns big Soundlabs speakers ( great speakers ) and we try several LPs ( any kind and " vintage " ) making changes on polarity and in all the records we heard a " dramatic " change for the better/worst. I comeback to my home and try the same with my system but the change here was/is really tiny.
It is more often on CDs that come with a change on phase than in LPs.
Like Dopague say: you have to be sure that your system is " wired " with absolute polarity through a test record. Of course that a polarity switch help a lot here but I think you don't have it in your preamp.
Regards and enjoy the music.
