Thorsten's numbers are misleading because he's equating timing resolution with sample rate and amplitude resolution with sample size. I believe he knows better but is just trying to oversimplify for a non-technical audience.
Ultimately, amplitude resolution and time resolution are characteristics of the encoded waveform, not its encoding format. Amplitude and time resolution are limited by the digital noise spectra. So for example, 1-bit DSD has better amplitude resolution than 16-bit PCM, and 352.4 KHz 24-bit PCM certainly has better timing resolution than DSD (even 192 KHz PCM probably does).
Using delta-sigma modulation with appropriate noise shaping, one can trade sample size vs. sample rate without loss of resolution. That's how delta-sigma DACs work.
