Why scratchy sounds Denafrips DAC to Drop AAA 789


Plugging Balanced connections of the Ares ll into Balanced headphone Drop AAA789… produces scratchy sounds to my Klipsch Cornwalls playing simultaneously… sharing of the Denafrips playing into a Rogue preamp. The headphone amp isn’t powered up. If I unplug the balanced union of the DAC and headphone amp, it goes away. The main Cornwalls are being powered by NAD C 1366BEEv2 amp. Any help on this one?

I know. It’s all over the place. 
The audio of my main speakers will take on an external distortion sound. My Blusound Node3, streams into Ares ii, which then connects to Rogue hybrid preamp, finally into NAD integrated amp. 
  When I attempt to additionally balance plug, the available BALANCED OUT to BALANCED IN of live Denafrips to my AAA789 headphone amp, “BINGO”… overriding scratciness sound to whatever music is currently playing… and the headphone amp is not active.
