**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.



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.

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.




**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. It is just a matter of how much trouble one is
willing to go to. Don't forget: A square wave, on a vinyl recording
(physically) looks like a triangle wave. 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.


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.
