I have a Pro Tools MixPlus+++++ system and currently use my Yamaha 02R for the mic preamp's and monitoring via Digi's ADAT bridge. I would like to loose the 02R because it takes up too much space and is not a great choice for mic preamps . I do not feel it worthwhile to spent a bundle on separate and expensive mic preamps and Line level to Light pipe A/Ds. . .

Can anyone answer me this? If yes, what kind of "protocol" is used for 96K on those MOTU Interfaces, those RME Multiface, and all the 96K converters around?
