If your priority with classical is neutrality, and it should be, you want the DT880. The 990 by comparison has ramped up bass and treble--fine for certain genres (rap, hip-hop anyone?) but wrong for classical. It might make certain recordings sound better but any aberration will do that. It's the result over a wide range of recordings that's important for long term satisfaction.
