In the DS the PCM upsamplers from 22.05k, 32k, 44.1k, 48k, 88.2k and 96k are all similar to the plot by Stereophile, tho I’d quote a different description of that plot: “With the tone, the second, third, and fourth harmonics, respectively at 38.2, 57.3, and 76.4kHz, can be seen, albeit at respectably low levels. But there is no trace of the aliasing product at 25kHz, this being completely suppressed by the reconstruction filter.”
Here’s the DS’s output of a 960Hz square wave sampled at 192k:
You can see the expected ringing of the IIR upsampling filter - it would be the same if it were an analog filter - band limited inputs have ringing and the PCM inputs are all bandlimited.
For reference here’s the theoretically perfect bandlimited 1k square wave (the squares are the sampling points):
I don’t have a convenient DSD test tone right now, but in general it will be sharper and the ringing will die down sooner. That’s the nature of the beast.
Here’s a plot that you can see at various places around the net:
