hey guys, just bought a pair of d2000's of the forums, and all was well. but ive been listening to them for the last week, and im beginning to pick up on some sort of crackling/scratching happening in the upper mids region. it varies from track to track obviously, but its either showing up more, or im tuning into it more now. i dont know if this is a source issue or a heaphone issue. ive been using an e17 usb'd playing rdio. some tracks ive noticed it in - lenka - the show death cab - tranatlanticism muse - uprising coheed and cambria - welcome home i can almost understand something guitar heavy, but the lenka song really throws me off. and its the worst offender! im hoping that its a source issue or some physical thing thats easily fixable vs simply having busted cans, as i really like the sound of them otherwise. anyone have any experience with something similar?
