yes.  Looking at PreAmp.net, I see the correct netlist along with the
correct reference designators.  ie:

[...]
unnamed_net7    C15-1 C13-2 R8-2 U1-3 
unnamed_net6    J3-1 R17-2 R16-1 C15-2 C13-1 R7-2 
GND     J4-2 J3-2 J2-1 C14-2 C9-2 C8-2 R15-1 C7-1 U2-4 C6-2 C5-2 C4-1 U1-4
R7-1 C3-2 C2-2 R5-1 
unnamed_net5    C8-1 R13-2 R9-2 R8-1 R6-1 R5-2 
[...]

The .pcb file ends up with:
