I am Panos and I am a nerd. I have been doing electronics since kindergarten. This is my first try with a PI media center.
As you can see, work in progress, I am waiting for DACs from HK.
I believe that no hat can be hifi. It can be descent but thats about it.
The linear power supplies are ready for the ordered DAC (DIYINHK ES9038Pro) for this implementation. Probably new Neutron Star clocks from NewClassD (No affiliation) also, lets see how it goes.
Also the PI and LCD are powered by linear PSUs with low noise regulators from NewClassD.
Why Volumio? Well, it seems its the best for the purpose out there.
