... I couldn't agree more that the original source is the primary determinant of sound quality, but I do hear differences between the same files when resolution increases.  Often, however, that seems most affected by volume level differences between the two versions under comparison...

 

Volume level doesn't change in simple bit depth or sample rate conversion. If you are doing the conversion yourself, then you are doing something wrong. If there is a difference in volume level between two versions of the same album that are supposed to differ in sample rate/bit-depth only, then someone is lying.
