I'm definitely not arguing for the stupid "audiophile" frequencies. For the tiny fraction of music taking advantage of ultrasonic frequencies and high dynamic range it's nice there's an option now.

I hope the availability of high resolution, or more importantly the spacial audio, will inspire some artists to really explore the space. I'm hoping for some stuff like the Flaming Lips' Zaireeka or Yoshimi album's 5.1 mix.
