Although that is technically possible, I have never heard of a CDT with build-in digital volume control. If you wanna run your DACs directly to the power amps, you may consider Z-Systems RDP-1 or TacT RCS for digital attenuation purposes. I have had the TacT RCS on loan, and inserted between my Theta CDT and Theta DAC, RCS sounded much better than my Krell KRC-3 preamp.
