channel imbalance = 0.005dB which is excellent !
Set amp to L gain.
Put music on and ensure the volume control is above '9 'o clock'
When you hear imbalance first try a mono signal. Hear if certain or all frequencies pan out of center.
Then swap L and R cable on the headphone. Does it stay the same then cable = O.K.
Then swap it back to normal and put the headphone the wrong way on you head (L on R of head) If it pans to the other side it's the headphone. If the sound pans to the left side its your hearing.
These tests should be enough to be conclusive.
