Troubleshooting balance issues

I'm hoping to get help troubleshooting balance issues I'm having with my system.  

Pre Amp is Parasound Halo P5.  Amplifier is Emotiva XPA-200.

I'm getting between 1.5-6dB less on the right channel than the left.

Below are the troubleshooting steps I've taken. I'm hoping you might have a couple other ideas:

  • All testing either with Mono recordings or single channel pink noise
  • Tried different interconnects
  • Ensured all connections good
  • Tried balanced and unbalanced connections into the emotiva amp
  • Tried through two different preamps
  • Swapped L/R output from amp to speaker and balance issue stayed on R output and switched to other speaker
  • Moved/swapped L speaker to the R side and vice versa
  • Measured L and R put with single channel pink noise
  • Swapped L/R 
Occasionally on a power cycle on the amp it will come back centered. Occasionally I'll get a full day centered. More often than not the R channel will be off -1.5 to -6 dB. The about of gain loss seems to stay stable (i.e. If -1.5 it will stay -1.5 for a while).

Would appreciate any additional ideas!!  

Thanks :)

Rebooting this..to the OP, did you solve this? Did you test this using headphones too?

I've experienced something similar using the P5 Preamp with active speakers. Noticed unbalanced sound in different pairs of headphones (but assuming that's a P5 headphone amp issue).
