Yes - thats what I meant more or less

The "internal switching" and amplifying etc. is all made *somewhere*.
If this process is done in xMon (as a part of the headphone circuit) then you could do a xMon replacement test.
If all this is done in the D-Dommand itself, you would have to borrow a D-Command ... or take your xMon to a friend who's running a D-Command and check it out there.
