Windows Seven with a Sennheiser HD 598 headphones I hear the difference from the sound card and headphone output of origin, on my speakers to 130 it also sounds better without being an exceptional gain. Its a little more detailed, richer (more controlled bass, balanced spectrum). Allow files to FLAC and MP3 forget if you want a real audio gain.
By GROS against black spot: the material does not work (at all) on Vista, so it is compatible XP and Seven. Incomprehensible oversight.
