"if you ignore the tonal balance, which can be remedied by an eq, would not you say the dt990s have better sq? i mean things that cannot really be changed such as soundstage size and depth, airiness, bass quality and the ability of the driver to create powerful and extended bass. detail retrieval etc. otherwise I am kind of confused as to why beyerdynamic would even make the dt990s and call them just" . . . .
