1. The perfect sinusoid unmasks the compensation of the system for imperfect power -- it is like when the car stereo comes on when you start the car, way too loud, because there is no road noise to adjust for any more. The sound of the capacitors might be polished and bloated, like a man in a finely tailored suit treading water in a large pool.

An interesting take, I never thought in this way. So, you feel that with a perfect sinusoid if sound gets worse then it not the fault of the powers source but rather the refection of imperfection of the rest playback. I personally do not think that it is the case but it definably a perspective that might be taking under consideration

2. Of course the method of sinusoid construction MATTERS, but how much? It is an indisputable fact from quantum physics. The effect is more subtle. The music is not as relaxed, not as open, the dynamics seem "disconnected." The music does not flow easily and the connection to the Sound is more removed.

Actually I do not know as I did not see the connection between the shapes of sinusoids as sound. When I have an “another” type of sinusoid shape I do not feed the system with different shape but with different methods of construction of sinusoids. It is possible that one method is sonically better than other and it is just happen that the “one method” has perfect sinusoids. To tell something defiantly it would be need to have let say am amp (A/B or D) that is driver from a generator and then feed the amp with different sinusoids – perfect and distorted. Then it will be objectively auditable is the shape of sinusoids (both current and voltage) is the factor in sound.  Otherwise we compare apples and oranges…
