1, The Compass 2  had infinite upgrade possible in future , the USB , DIR, DA, ACSS modules can exchange without solder . ( All analog signal transfer in current model for avoid the sound degrade by the modules sockets . Digital signal have the impedance match for avoid sound degrade by the modules sockets . )
    DA modules :  ES9018 sound characteristic is very neutral and a ton of details without harsh, bass is speed and control . 
                           Dual PCM5102 sound characteristic isneutral and a ton of details , bass is strong and rich . 
                           Dual WM8741 sound characteristic is slight on warm side and smooth ,  bass is deep and rich . 
    DIR modules : Users  can choice the SPDIF signal feed to either ES9018 direct and through DIR module with 3 jumpers setting , which is simply for users choice different sound flavors . Other DA modules must setting with DIR active model .
                          WM8805 sound slight warmer , support up to 192KHz .
                          DIR9001 sound quite neutral, support up to 96KHz .
    OPAs : Users can exchange the OPA chips and discrete OPA modules for Line in without solder ( The USB, coaxial and optical inputs is applied the built in DAC, it transfer signal to the built in amp direct without any OPAs , so replace the OPA have not effect the sound on USB, coaxial and optical inputs  ).
                          OPA-SUN sound dynamic ,detail and speed .
                          OPA-EARTH sound is neutral but slight warmer .
                          OPA-MOON sound is a bit warm and smooth .
2, The Compass 2 have Line in,  users can use it as a dedicate head amp / preamp .
3, The Compass 2 have Line out , users can use it as variable level as DAC with preamp combo or fixed output level as dedicated DAC .

Summarize:
Fully  discrete analog stages without any OPA and couple caps in the signal channels. ( Built in DAC and head amp)
