I can also for those interested my motherboad, see original GB: GB for Pioneer Super Linear Motherboard

It makes construction and assembly much more easier... If there is enough interest I can make an other small pcb order.

Interest for XEN Headphone Amplifier Motherboard

You are of course free to choose.
I don't mind either way, as the motherboard is a lot of work.

I've just increased my order to 2 sets. I saw in the documentation that a lower powered version can be powered by Silent Switchers. I've got two Silent Switchers doing nothing so this seems like a good use for them.

You should check what is the maximum current for the SS at +/-15V.
And most likely one SS for each channel.

If SS is powered with 9V 2A it can deliver 300mA to +/-15V output.
