Uhm wait. Isn't that Coax input only?Maybe.
I forgot about the Coax output.
The other issue is sound quality. The difference is in the quality of the DAC chips , op-amps, etc. Portable units have to balance size vs features/quality.
The Hugo 2 TT has more taps than the Hugo 2 (going from memory, so I could be wrong), plus multiple types of outputs.
I wish they would switch to USB-C but that would break some of their compatibility w their plugins. (Maybe offer an adapter?)
But again, look at the price jump.
Sorry, that would mean that you split the headphone out into left/right RCA plug ot some similar special cable.
