Actually, the output from any DAC I've owned had no steps whatsoever. I've looked at the output on an oscilloscope and I've measured distortion using a spectrum analyzer. If there were even the slightest hint of steps in a DAC's sine wave output, it would produce gross distortion. However, sine wave distortion on all the DACs I've measured was below 0.01%. Many of my DACs had less than 0.005% distortion.
The output waveform from a DAC is filtered, which removes any steps. Even at 20-kHz, the sine waves from a test CD appear as perfect sine waves on an oscilloscope screen with distortion well below 0.01%, and there's only two samples per waveform at that frequency.
