UR28M Converter Quality

Parlopower’s observances here: http://www.gearslutz.com/board/music-computers/705015-steinberg-ur28m.html

are being quoted as fact here: http://www.gearslutz.com/board/music-computers/718258-steinberg-ur28m.html

I’ve searched and can’t find any other source for the claim other than one Gearslutz poster’s opinion.

I would like to hear from Steinberg whether there is validity to the claim that the converters in the UR28M are different from the converters in the UR824.
