Another comment is about this "accuracy" you are looking for. For me, the "accuracy" is nothing but maybe the biggest myth in audio industry. There is not such a thing, we can have audio that sounds realistic to your ears, but thats about itAccuracy is the goal here,meaning to reproduce the signal without any coloration,since all speakers do color the sound to a degree, so it may be unattainable,but certainly it is not a myth.
