It has to do with the gain of the amp. Higher gain will allow you to use less of digital volume. The lower this drops, the better. 0 is best of course, but you will need really high gain to get this. The rule of thumb that I use is no more than -10dB or it will impact SQ. If you are using ONLY digital volume, it will likely require at least -20dB.
BTW, the DAC2 sounds best when driven with I2S, either from the PWT or the Off-Ramp 5 HDMI from a computer.
