You should look into JVCs. HA-FXD70s. I haven't heard the Amperors but for rock alternative acoustic music. These are one of the best. These use Carbon nanotubes and throw out some seriously high end detailed sound with speed and great balanced sound. Try em out. Another plus is they don't cost much for their sound.
