The absolute phase of recordings is not consistent. Most are in "normal" polarity but quite a few are in reverse polarity, perhaps because one of the preamps or processors in the studio inverted phase.
Some preamps have a polarity reversal switch (mine does) so that you don’t have to switch the speaker wires to listen for which way sounds correct.
