Hifi, why bother?

I have just looked at my last post this morning and realised my electronic theory is somewhat out lol. A regular square wave is defined in odd harmonics, although at defined amplitudes. It's the non regular in which even harmonics come into play. It does make things easier though as a regular square wave, although sounding harsher than a sine wave, is not nasty and muddy (or perhaps dischordant    ).
