After a day or so of tinkering, I found out my plasma was causing the noise, potentially with the DC voltage in the line issue that isn't uncommon.

Only device I found to combat this was the Emotiva CMX-2. Got it in today and fixed it perfectly. Anyone that runs into the issue and thinks it is a DC issue, give this thing a try.
