Bit hard to build it without a PCB to build it on. The first group buy for blank boards still hasn't finished yet.
But yes, i will be building it.

What do you mean? :question:

I might be interested in trying my hand at some DYI magic myself...

The printed circuit board (PCB) for the design, where all the components are populated/soldered - they're not available for purchase anywhere at this stage.
There's a group buy for the boards at diyaudio, along with some group buys for parts, etc.

Oh gotcha cheers!

That was actually lucky you mentioned that because today is the last day of the group buy... anyway I ordered 2 PCBs, see how we go.

Noticed with the group buy boards looks like they've gone for some sort of funky gold immersion plating and black solder mask.
I had to lol given the objective ethos of the whole design, but the increase in cost was minimal, so i don't really care.

That's for the Australian group buy, however I ordered 2 boards from the DIY Audio thread (UK)... I wonder if I can upgrade my order to the more funky ones. :confused:

I can't quite work out if they are going to upgrade the whole lot of do 2 runs, I'm not fussed either way, it will make zero difference to the performance.
