You were told wrong information. The only time you would reverse polarity is when something is recorded out of phase and it bothers you enough to correct it. BTW, many can't even hear the difference. Leave it alone and enjoy it!
Rogue Metis speaker polirity
Can anyone help me I just got a Rogue Metis preamp. I was told I need to reverse the polirity at the speakers. The manual says nothing about this. Any help?
