I asked this question over at XDA, but nobody seems to know. Actually, I have two questions.
One is in the title. I'd like to know what the Galaxy Nexus GT-i9250M (maguro, not toro/toroplus) has for output impedance on the headphone jack. I suspect it may not be near-zero... and I am wondering how much it may be degrading the sound of my headphones (13 ohm UE SF5 vi).
The other question is... if nobody knows what the maguro's output impedance is, does anyone know how I can measure it?
