Well, this is more of a discovery on my part, and I wanted to share my findings. I'm using Foobar2K with a polarity inversion dsp, and the resulting sound is pretty different. Headphones are AD2000Xs. Spoiler: Illustrations Overall, the sound is wider and more out of your head sounding. On some songs, there are some sounds that sound the same regardless of the polarity (mainly treble-centric atmospheric sounds). It sounds really unique, and I think I like it more than a normal polarity, especially in the bass. It also emphasizes the separation between the channels. For example, if a particular sound is closer to the right channel than the left, it will sound like it's on the right channel even more with the polarity inverted. With the polarity normal, there is less distinction, and actually sounds more in the center on said sounds. VST Plugin is called Polarity Off does nothing. L inverts the left channel, and R inverts the right channel. Both L and R sound the same, but L+R sounds the same as off. Download Here (bottom of page where DualPanner is at). You'll need a vst plugin component for foobar in order to use it. I use this one. Give it a try! It sounds pretty neat, imo.
