Another approach would be a passive pre between Dac and amp. If using a DAC with tube output stage into a tube amplifier one has plenty of tube driven gain.
One can find tube amplifiers that have variable input gain to better control system gain. The maker of my presmp, Aric Audio, makes tube amplifiers that have this such that one can run a fixed gain DAC directly into the amp. His amps have 6SN7 tibes in the input and driver stages.
