Good evening everyone I'm an amateur audio "enthusiast" - well, I'm somewhat interested in the world of premium audio, I suppose, but I'm definitely an amateur. I have a two-day old pair of Sennheiser HD-595s connected directly to a Sound Blaster X-Fi XtremeGamer. The 595s have about 24 hours of burn-in time. As I was listening to some music and testing out various EQ settings and volume controls, I noticed some popping and crackling... a LOT of it. When the volume is turned all the way up (and for some reason I feel like I need to put it at 100%), the crackling starts to occur. If I even THINK about touching the lower frequencies on the EQ, the crackling & popping goes crazy. Could this be due to the sound card itself? Certainly the 595s aren't to blame for this? They're fresh out of the box, yes, but they have some burn-in - perhaps not enough, I suppose. Any assistance you fine folks could provide would be greatly appreciated.
