Anon, don't blame the equipment for your lack of knowledge.
That's what a bandwidth limited square wave looks like.
Human ears only hear frequencies up to ~20khz at best, so there's not much reason for audio equipment to have more bandwidth than that.
A 1KHz square wave only has 10 harmonics under 20KHz, so that looks exactly how one would expect.
