I gathered that with 16 Ohms of impedance, they didn't needed that much power, but i was thinking about what gikigill said, when he amped the headphones the mids got more present and it cleared a little. Considering that the S400/S500 are also light headphones, but benefit greatly from an amped source (gaining clarity and a litt, i was wondering if the SZ2000 did this too, or was just a difference in power/volume that cleared the headphone...
Also, gikigill, i was wondering how does this HP compares to the response that the HD25-1 has (one of my all-time favorite headphones), mainly in the detailing of the phones.
