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.
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
