If the dac sounds better because it’s got an output tube instead of ss, it was probably a bad sounding dac, and the tube is just a bandaid fix.
Also dacs with tube output don’t drive very well into the next equipment, be it passive pre active pre or direct to poweramp if it is lower than <20kohm input impedance.
As tube dacs usually have high output impedance and are capacitor coupled, which "could" also roll off the bass those low input impedances <20kohm.
