I noticed that the left channel of my HD600s was making a slight buzz on some frequencies.
If anyone has the Radiohead song "No Surprises", turn up your amp loud and listen to the intro. Is there an annoying buzz in either channel?
For this song specifically I noticed the left channel to have a loud buzz instead of the bass notes.
I downloaded a bass test that goes through the lower frequencies. Near the end of this test (20-60Hz?) the left channel would start to buzz. Turn the volume up a little more, and both left and right buzz. Worried that I had damaged my HD600s at some point, I took out my EL2001s from my META42. This improved the situation a bit - the left channel no longer buzzes at lower volumes than the right. Then I swapped out my AD8610s for a AD823. This improved the problem a little more, now the buzzing starts at a slightly higher volume. HOPING that voltage is the issue, i checked my voltage and found +/- 5.5V (damn batteries go fast).
Is this likely the problem? +/- 5.5V for AD8610/AD823 not enough for low frequencies?
