Hi,
The DAC output will have around 2.5 to 3V DC on it. I would not recommend to connect this directly.
If using a 100K Volume control I would recommend at least 0.22uF coupling cap's between DAC and Volume control.
Incidentally, I should mention that I dug out the original French scheme from l'Audiophile of the ciruit in the Monica and suggested replacing the original Batteries used (1.5V * 3) with a diode string and CCS, as shown in the schematic, that was around the turn of the century on a Gainclone board IIRC...
Bottom line, I think you and your tubes will be happier with a coupling cap.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
