We used to use squarewaves for the following.
To show how bad tape machines were...
To show the tone control effects

However, you need to look at the harmonics on a true square wave,
which of course cannot actually exist.

**If you REALLY want to laugh, look at a 7kHz square wave from a CD
player (even 5kHz is barely passable from most CD players). A good
R-R or high end vinyl playback can do a MUCH better job.

Bull****

**Red Book CD tops out at 22.05kHz. A decent RR can easily top 30kHz. A top
of the line vinyl rig can easily manage 60kHz. Do the math.
