Something to ponder: Why does DSD (SACD) work?

Because it's a different data stream and it's not PCM.


But how do they make 1 bit work if it can only be off or full 6dB?
The point is that digital doesn't actually work that way.

But it *is* PCM. Sampling rate and word depth can be traded
pretty liberally, I think is your point. Greater word depth
reduces the ambiguity of quantization, and ambiguity is
"like" noise.

I still have two problems with the discussion so far. First,
Bob Cain's caveat remains unaddressed:
"Within the Nyquist criterion a signal can be produced with
any arbitary phase or delay until you consider the
quantization of the samples. Then the achievable delays
become quantized as well "

Second, quantization degrades the theoretical perfection
of Nyquist criterion signals to a greater extent for
smaller signals, IOW, the conversion is not monotonic.

Thanks for your excellent comments,
