Is the problem in the headphone output only?  Or also in the main outs?  Is
it just one channel, or both left and right?  If it's just he headphone out,
consider a headphone amp on the line outs.  Many available have pass-thrus,
so you could send the main outs to the headphone amp, then pass through to
the rest of your rig.  That should cost less than the mainboard swap.  Of
course, this is DIY.  You could probably build the circuit fairly easily....
