There could be a number of reasons for that. The first place to look is at how your friend's self-designed handmade r-2r converter measures at 12-bits, versus 16-bits. Designing and building high-resolution, consistently high-performance converters is not a trivial task. For just one example, the converter may be non-monotonic below 12-bits, making possible that it produce more distortion at 16-bits than it does at 12-bits. The bit-resolution does not determine the distortion. 1-bit converters, such as are used for DSD, inherently exhibit excellent distortion performance.
