A related question to the H590 -- I just realized that it doesn't have a headphone output.
Is there a clean way to utilize the DAC/pre-amp on the device with headphones? My concern is that feeding the variable-output/fixed-line output from the H590 to an external headphone amp would leave the speakers in the H590 on. Does anyone know if "muting" the H590 will leave the variable-output/fixed-line outputs active (there by allowing me to mute the speakers while still driving the headphone amp.).
