I recently moved and put my theater back together with some upgrades. I remember having issues with my right rear channel in the old place but figured it was either a blown Polk or cabling may just have been an issue in the walls (I put it in 15 years ago).

But in this new space (not as "dedicated" of a theater as my old one), I have the ability to test the issue a lot more since everything as far easier to get to.

The sound out of that channel is significantly lower then my left rear. Even Audyssey will set that speaker to +6db vs the left with does even it out.

I have swapped amps (Outlaw 2200 monoblock)
I have swapped speakers, went from Polk floor standing to Paradigm ADP v5
I have swapped cables.

The issue still exists. Should I just assume there is something wrong with the xlr port on my Marantz now?

Try the RCA in comparison to the other RCAs, of course.

Good idea, I just tested with a typical 6 foot Monoprice RCA and its actually the same, still have to raise the db by 6 on that channel to make it sound equal.

Must be internal to the Marantz. Are you playing "Direct" and without any processing?
