Could this be the cause of the "tizz", type vibration that I hear sometimes with certain vocals at a little higher volume? I hear this in the treble though....it would be my only complaint about the sound of the HE-560. and a few others mentioned this as well in the review thread. I was hoping this would go away with more burn in. Voices such as Linda Ronstadt, Loreena McKinnet, Allison Krause, as examples. male vocal Brendan Perry. Certain treble frequencies seem to resonate slightly. Can be repeated at the same point of the song!
Can you share what exact tracks and locations you hear the "tizz" so we also can test and see if our copies have the same problem? I've listened to a couple of Allison's albums with HE560, but I didn't hear the "tizz" you talked about.
On a quick listen of "Paper Airplane", 24/96 flac recording, the song "Dimming of the Day", multiple times throughout the track when Allison sings the word "need you", or the word "need", she gets breathy/shouty/tizz, when she increases the volume of her voice inflection, during that word, I hear what I was trying to describe on the HE-560, but not on my other phones, DT880, etc! I would need to listen, and do some digging in some of my other tracks to pinpoint that same thing, but that is pretty much the distraction right there!
