HI, So I decided to dress up the Protodac some. I picked up a case for it, and installed the Pi which is a PI2 inside and then i placed the Dac Hat seperately and connected it via the GPIO pins needed. The case is a Mini Thin ITX fanless case all aluminum. I had to come up with a back plate as the one it cae with wasnt going to work out. I modified a back panel from another projects and wired up some gold plated RCA's and ran shielded wire from inderneaqth the Protodac board to each RCA. The RCA that were originally were not coming off without a fight and seeing how many times Ive had to solder resolder things on the board I didint wanna temp fate. For power I added a DC barrel jacl and then on insde stripped down Micro USb cable and wired it that way, I may change that. Im powering it with a Linear power supply. Today I fired it all up and after a few tweaks she sounds fabulous. I plan on integrating the power on off on front case but for now its not wired.
