I've had the R2R-11 and now currently run the R28.
Although I much prefer the R28, I think the R2R-11 appeals to a broader audience as it is substantially cheaper and a whole lot smaller so easier to place on a desk.
That being said, I don't see Kingwa offering units to Massdrop at cheaper prices to suit the Massdrop business model, and to my knowldege, Audio-gd is not a mass production facility. They mostly build to order.
