Ok. So I’ve already done the speaker swap. And now I switched the speaker wires at the out put on my receiver and the problem travelled. ( one channel quieter than the other. ) This leads me to believe it’s the receiver and probably the pot / attenuator sensitivity. Nice to know it’s not a major room boundary or something.

Guess I’m gonna pull it all out and clean it. I’m watching videos on how to deox it. Will this be enough , I guess we ll see. Any other tips ?

Listened to DSOTM on a regular CD. Fabulous at medium loud volumes. ( seems the channel imbalance disappears at louder SPL).
