we'd like to have enough resolution to
reproduce the waveforms
This is exactly what the Nyquist theorem promises. You can reproduce
any signal below SR/2. If this signal is not a sine wave, then it must
contain more higher frequencies and at that time, you don't follow the
Nyquist rule. Only two values are enough to mathematically reproduce
an exact waveform; even more precise than you can sample it.
