[sdiy] Digital is more analog than analog... and it has 319 dB headroom...

The "300dB" dynamic range of "digital" totally misses the point. It
has nothing directly to do with DR. It DOES keep the noise and
distortion from building up and becoming audible after dozens,
hundreds, or even billions of MAC-type operations on each 64-bit
floating-point number. Surely he knows that, but it may be harder to
describe and is "less impressive" than the dynamic range of lots of
bits.
