DJK,A colorful analogy - like counting one's friends on a hand of amputated fingers!!
The symmetry argument concerning amplifiers is not, in my view, too relevant, although it is pleasing as all humans love symmetry.
Asymmetrical treatment of positive and negative half cycles leads to even order harmonic distortion of the fundamental, which is primarily musical, at least to the fourth harmonic. Symmetrical distortion of the half cycles, while far harder to spot and arguably of lower total magnitude in a fully symmetrical design like the Leach, leads to identical distortions on each half cycle which defines as odd order harmonic distortion of the fundamental. This is not so musical, and by the 5th harmonic, actually quite objectionable. It is essentially this order of distortion which creates so many nasties in the sonic presentation of solid state amplifiers, though tubes can do it too.
I hope my post does not offend.
Cheers,
