Does your MacBook Pro outputs 24/96 data or 16/48. If 16/48 or 16/44.1 then your Bel canto or Ramp will upsamample your signal only. If that is the true then its much better for you to let uour main DAC (here AEC) to do all signal manipulation you want.
I believe that Ramp 3 also reduce jitter and if its true then its the reason to consider its use in light of your main DAC capabilities
