Here's what I've never understood, isn't Nyquist sampling discrete in time but continuous in amplitude? If the amplitude is instead (as is normal in digital) being sampled discretely (in steps), wouldn't that introduce errors, and wouldn't more samples make up for these errors? what would Nyquist in amplitude, continuous in time look like? that's sort of a class D amplifier, and even sort of CVSD.

There are Sigma Delta ADCs, which sample quantised to one bit at a higher frequency. They need to do some processing in the analogue domain though. IIRC you need to multiply the sample rate by 4*N to get the equivalent of an N but DAC
