So Ive had these now for 3 weeks or so. Im pairing them with an ebay Dac/Amp( this one ) using Itunes with mostly lossless files that I ripped myself.
Ive started noticing some crackling/something at certain frequencies. I have a hard time describing it, but at the 4min mark of Coldplay's Lovers in Japan, when it slows down and the piano comes in I can hear crackling in both channels each time the piano gets more prominent. I notice it in many other songs too, but since I listen to alot of metal and hard rock, I only notice it during intros and then cant hear it during the rest of the song.
I tested it using the Dac and straight out of the laptop as well, I can hear it from both.
Edit: As I was writing this I also just tested straight from my Ipod, using the coldplay song, and I cant hear the crackling.
So maybe its the laptop? or some settings in itunes? I have no idea. Hopefully its not the headphones....
