**16/44 digital can't even reproduce a decent 5kHz square wave.

Well, it would have the fundamental and third harmonic so the
resulting wave would have plenty of ripple.

**I'll give you a hint: It looks nothing like a square wave.

Kinda-sorta. It not like most cartridges put out perfect square waves,
either. MC cardtridges often ring quite a bit.

Such a
feat is a doddle for a good vinyl system. Do you think you can hear
the difference between a 5kHz square wave and a 5kHz sine wave?
Hint: You probably can.

Probably can, but what sort of musical instrument produces square
waves?

**None. But that is not the point. Many instruments can produce fast
leading edges. Cymbals, for instance.

However, sounds produced by those instruments can't be distinguished when
downsampled from say 24/96 (better square waves than any vinyl!) to 44/16.

And ... what sort of loudspeakers can reproduce a square wave? I
think the Quad ESLs can.

**The old Duntech range was designed to reproduce step waveforms with
startling accuracy.

As shown by test equipment.

**Nope. In fact, a good vinyl recording can go well past 50kHz.

surely you mean "a good analogue recording transcribed to vinyl"?
I mentioned before that I was under the impression that vinyl
cutters have trouble etching high frequencies onto the vinyl.

**Then you'd be wrong. There is no reason why *any* waveform cannot be
coaxed onto a vinyl disk.

Sure there is: the problem of tracking it, once cut. Cartridges have styli
with finite radii.

It is just a matter of how much trouble one
is willing to go to.

And how irrelevant you think write-only memory is.

Don't forget: A square wave, on a vinyl recording
(physically) looks like a triangle wave.

Except for the effects of RIAA equalization.

BTW: I have a CBS test disk
with square waves recorded on it. They appear on a 'scope with far
higher fidelity (provided I use a high quality turntable) than any
16/44 digital system.

But not as good as 24/96 which sounds no different when downsampled to
16/44.

The mighty Dynavector 10D-II can operate to 60kHz.
The square wave
performance of this very fine cartridge is exemplary.

that is the performance of the cartridge, not the LP

**It is the thereorectical performance of the SYSTEM. Rarely, if ever,
achieved in practice.

And due to the properties of ears, rooms, and speakers, its all irrelevant
to sound quality.
