How to tell if lp is recorded with phase reversed?

I'm just wondering what is the best tipoff that an lp is recorded with phase reversed. I have a PS Audio GCPH, so reversing phase is easily accomplished. I have listened both ways, on some lp's it seems to sound better with phase reversed, but what are the obvious signs, or are there any? Thanks, Dan

FYI, Silent Running Audio has an Absolute Phase chart that you can download which lists the recording labels that had a tendency towards recording in phase vs inverting. This is just a guideline but may be helpful.

Just look at the woofer. When drum is played, woofer should move outward. If it moves inward, phase is reversed.

If the singer (soloist) comes from between the 2 speakers its in phase. If the soloist is difussed and no where in particular, its out of phase.

Buffyjames, you're talking about what happens when one speaker is connected out of phase. That's not the same thing as polarity switching.

Buffyjames,

that's if the two channels are out of phase from each other, ie. if one of your speaker's wires are reversed. No relation to what we've been talking about.
