I think I know what you mean. They aren't as wide as others. To use an analogy, I think about soundstage like a clock. My HD600s and DT900s have sound wide at 9 and 3 o'clock, as well as sound at 12. That's sort of 3-blob to me. The 1540s also have sound at 10, 11, 1, and 2, but the 9 and 3 aren't as wide apart as the HD600s and Dt990s. Overall, I really like it. It really seems to work for me.
