Please excuse me if this is in the wrong section as I am new to Head-Fi. I have Sennheiser HD 650s w/ a stock cable and they are running off a Zero DAC/Headphone Amp. When I listen to my music the audio seems to be very slightly biased to the left speaker. However, when I run it straight from my Macbook Pro, the audio seems slightly biased to the right speaker. Is there something wrong with the Zero Amp or is this just the music file? Help would be greatly appreciated. Thanks!
 
 
I forgot to mention my audio source is a Macbook Pro connected to the Zero Dac through an optical to Toslink cable.

The Zero is notorious for having a bad volume attenuator.  At low volumes, the sound is biased toward the left for me as well.  I have an older Zero before it received an update with USB.  For this reason, I just use the Zero as a DAC an have it output to my LCIII.  I heard that people have had luck swapping out the volume attenuator but I don't know where that guide is.

Glad I'm not the only one. Thanks for the help!
