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.

Sorry. Apples and oranges.

I once built a two transistor pre-amp that was flat from 10 Hz to over 2
MHz. Thing is, it didn't have all that good of a distortion figure.
Digitally reproduced analog waveforms have distortion. There is simply no
way around it. You cannot make a true, perfect sine waveform out of a bunch
of square waves. It can't be done.

Further, the universe is most certainly not digital. About the closest thing
you get to digital in the universe is a hydrogen atom. But even the radio
frequency wave output from a hydrogen atom is a sine wave: analog. Digital
can only be a representation, in various degrees of fidelity, of an analog
signal.

Yes, but the error from a perfect sine wave may be extremely small. In fact
much lower than the noise in most analog recording methods.

The same can be said for analog recording systems. They also introduce noise
and distortion into the analog signal.

I work with a lot of 20 to 30 year olds and many of them have a severe
hearing loss, listening to their car stereos is nearly torture for
anyone who can hear normally, they almost all have a huge boost on the
top end. It sounds horrible, but they think it's great. My one friend is
deaf from jet engine noise, but he's 60 years old, not 23. By the time
these kids are 50-60 they will be stone deaf.

The universe is analog not digital so you get over it. Quantum physics
stating the universe is digital is an oversimplification at best and I'm
being very generous.

By the way, you have already been assimilated by the analog borg.

Radio is my hobby.

That your personal biochemistry can't resolve the refresh rate only

You need to be more generous to yourself and not be so quick to
dismiss things that overwhelm your intellect.

You are clearly the one overwhelmed. We don't operate at the quantum
level and neither do objects larger than the chained molecular level
that we interact with so don't be so stupid to conjecture that because
the science of fundamental matter has quanta energy levels that is the
way macro physics world operates because it doesn't.

This is a good analogy to your missive.
