I think that you pose is an interesting question. I too have noticed that some DACs seem to subjectively produce a stronger or more full bass than do others, even though both feature a flat measured frequency response extending down to at least 20Hz. DACs are probably the most complex of audio components, having many circuit aspects which could alter the subjective sound while still exhibiting a flat 20Hz-20kHz frequency response. Circuit aspects such as jitter, and ultrasonic image rejection profiles readily come to mind.I would expand the context of this question to include other components as well, such as preamps. The power supply often comes up as the culprit, however, any circuit will only consume so much power, regardless of the amount of power potentially available. Overkill of the power supply's current capability, especially for a DAC or preamp application, cannot be the primary cause of any improvement in circuit performance - assuming properly effective voltage regulation, of course. It seems that it must be due to some secondary factors. I suspect, but have not confirmed, that this has to do with the dynamic behavior of a given circuit. Both the time domain behavior, and changes in the distortion profile over the dynamic envelope of the circuit and it's power supply operating together as a joint entity.
