I don't care how many
samples you take of a complex waveform with an ADC/DAC system, the resultant
playback waveform will never represent the original analog waveform as well
as a high end analog device. Even a simple 1000 Hz sine wave will not come
out as a pure sine wave after digital conversion, it will be a series of
stepped square waves. You may not be able to tell the difference with your
ear, as long as there are enough of those little steps, but that's not the
point. The point is, it will not "run circles around" a high end analog
device.


Nonsense.

Format 1 bit DSD (Direct Stream Digital)
Sampling frequency 2.8224 MHz
Dynamic range 120 dB
Frequency range 20 Hz - 50 kHz

The SACD format is capable of delivering a dynamic range of 120 dB
from 20 Hz to 20 kHz and an extended frequency response up to 100 kHz!
Try to duplicate that with any "high-end analog device".

Quantum physicists state the universe is digital. It is your inferior
sensory organs which can not resolve the digital universe.
Get over it! Radio is the enemy - ANALog is dead!
