I plan on making the power supply as affordable as possible. It will be DIY to install, but shouldn't involve more than soldering a few wires and mounting the pcb inside the unit. There will be pictures and detailed instructions, and it's really very straight forward.
I won't be selling the dcx2496... simply because I've seen it online and on Ebay for less than my cost. So not much point in that

The same with the Canare star quad cables. I'll have a tutorial on how to install and use the device soon enough that should answer everyone's questions.
