Well the left channel is buzzing now, more with Stax SRM and less with the E/90 but with both (barely audbile with the E/90). It's something to do with the bias voltage because it buzzes even after being detached from the amps. One would think the E/90's higher bias would cause more buzzing but who knows.
I opened the driver up and took a look and nothing is obvious (though it may be in backwards since to line up with cable entry the wire needed to be flipped). I guess I will be sending these to Koss for repair yet again. Which will probably take 2 trips because they will say there is no buzz with the E/90 because they're deaf (as shown by the last fiasco). Which means I will be without a pair of headphones when my KGSS arrives.
Fuck these headphones. :mad:
