The PecanPI streamer is fully assembled and ready to go with the software installed.

The DAC you need to assemble and install software on your own.

So you charge $175 for assembly of the very easy kit + free software? That's almost 80% of the kit price. Wow.

I remember the first time I set up a Pi it took me days of heartache and wasted time.

The price for the dac is pcb only, the streamer includes all the other bits and the case and seems to represent fine value.

No the kit costs $350.

$225 is just for the DAC, the case adds another $125. Assembly and installation of software ends up being $50. I cannot charge any less than that considering how much time in involved.
