I use a DAC going direct to AHB2 to speakers with either digital volume control in a DAC or software volume control. While using an analog preamp can theoretically preserve the signal to noise ratio as I reduce the volume it makes no difference practically at all since the noise floor is well below 0 dB SPL even at the highest volume. I can put my ear right at the drivers and I hear nothing. So when I reduce volume digitally I am still getting the best possible dynamic range as far as my listening is concerned at whatever volume I choose to listen to. And I have always preferred using digital volume control to an analog preamp in this set up.
