So I swapped the preouts from the Yamaha into the P7 and the hum doesn’t seem to change much if at all. I also turned off the Yamaha while the leaving everything else on and p7 in HT bypass and hum still exists, no change.
Once I unplug those interconnects coming out of the Yamaha into the p7, the hum disappears.
So I think I fixed it! The Parasound A21 amp has two options for Input, balanced and unbalanced connections. I removed my balanced XLR cables from it and the p7, and replaced the pair with good old RCA cables, flipped the switch on back of the A21 and guess what, the buzz is nearly inaudible!!
I have no clue why this fixed it but so far so good
Something not good with the XLR cables, maybe.
