And when it is explained that clearly, it is obviously wrong.
DSD is just as digital as PCM, in that the signal is stored in discrete, quantized values at a constant sample rate. Just because one system uses a higher sample rate but a smaller number of bits (1, in the case of DSD) doesn't make one "analog" and the other "digital".
DSD and PCM, from a digital storage standpoint are both quantized, in that they are two level digital in form at a fixed clock rate, but only PCM has an actual quantized weight that expresses a value. Like a voltmeter, it can be decoded to an actual voltage at that sample time. DSD (1-bit two level Pulse Density Modulation) expresses only relative change indicators each sample time, and no weight information. It is analog in that the DSD (1-bit two level) pulse stream is a continuous modulated pulse density stream of relative amplitude values when decoded, ie, low pass filtered. Follow the sequence in the table in the middle of the page to understand the workings of a first order Pulse Density Modulation Delta-Sigma Modulator:

DSD (1-bit two level Pulse Density Modulation) is not Pulse Width Modulation, although they are in the same family.
"DSD Wide" is not PCM. It is a multi-bit (8) two level Pulse Density Modulation pulse stream, like 1-bit two level PDM, where there is still no quantized value ala PCM, but a 8-bit word based relative value from sample to sample like 1-bit two level PDM (DSD), where there is a binary relationship between the 8 bits. Therefore there is a binary weighted relationship between samples that is processable in a computer. Of course PDM has to operate at a much higher sampling rate than PCM, relative to the signal bandwidth, to allow enough samples to recognize the fastest transients. PCM is a frame/sample based system of 2's compliment binary format of actual amplitude values. It is MUCH less efficient than PDM due to all the redundant data carried from sample to sample, and therefore less resolution than PDM for the same data rate. It's the primary no one outside audio uses it.
