And that one for the top notch golden ears audio enthusiast

Do you get better quality sound from p-type semiconductors or from
n-type? It seems to me that electron-majority-carrier materials would
be more like tubes, but all that bouncing around in the crystal might
add unwanted echos, so hole-majority carriers might actually exceed
tube quality in certain golden-ear-only-measurable factors.

Has anyone looked (I mean, listened)? If not, how do I go about
getting a grant to hire some golden ears and set up some ABX tests?
