Why not give things a listen and find out for yourself if you can hear a difference when the absolute phase is changed? That makes more sense than agonizing over something you may not be able to hear.You are not being snarky at all. I have no idea if I can hear phase differences in recordings because I don't know which recording was recorded in what phase. My ears are not super discerning.
I have the CJ ET 5 preamp. I do believe most if not all CJ
preamps invert phase
