I got a new amp, new DAC, new speakers, made sure my cables were the same length, set them the same distance from me, and noticed something that hadn't bothered me before--the vocal track is always slightly left of center. I can move it to the direct center by boosting my right channel volume, but I have to wonder. Is that how it's supposed to be? Maybe I'm losing hearing in one ear faster than the other? Maybe Windows is being dumb? Help me out here
