Hello, I have problem with my headphones. It's actually my second headphone (first was Hifiman Sundara and now Hifiman Ananda) and they somehow shares the issue. So, when i run sweep tones generated by SoX i hear high pitch squealing or grain at certain frequencies. I noticed it on both channels (not at the same time and at different frequencies. I tried 2 cables (my first guess it's cable issue, because hifiman have ****** cable, see pic
), tried to connect it to 0404 headphone amp and to O2 amp (using 0404 as DAC). Also tried connect it to PC directly. Nothing helps. It still possibly cable issue, but could it be something else? I have no idea. Maybe this is normal?
