So I'm using a few external dacs/headphone amps with my iPad. My nuforce volume adjusts volume when I adjust my iPad volume vs my hpp1 doesn't allow me to adjust the volume on my iPad but only the dac. If this was a true dac I would think the iPad volume would not matter as it would be a pure digital out to the dac. What am I missing?

It is a "true dac". The iPad is adjusting the volume in the digital domain.

If you have a 24 or 32 bit DAC, adjusting the digital volume should have no degradation of sound quality.
