Oops forgot this thread.
Listening now at work through cheapo Samsung earbuds (roughly corrected/sweetened using the EQ in VLC).
My preference is B, C, A. In that order.
B is darkest in its raw timbre and sounds to have the lowest distortion.
A and B are more similar, but A seems to have a bit more distortion, a touch more brightness and less depth.
PM me the reveal if you will.
