Psag - if you don't need analog inputs then you can go for the Tact 2.2 mini. The only difference between that and the 2.2XP (as far as I can tell) is that the mini does not have analog inputs. Both units have digital outputs.
Note that using the TacT unit you can set the output bit rate different from the input bit rate i.e. you can use it as an upsampler. Infact it is best to do this since the TacT upsamples everything to 24/96 or so internally to do the room correction and then upsamples or downsamples the output.
See the manual esp pages 12/13
