Got my new AMP+ today in the mail. Bought a 120v to 15v linear power supply and temporarily wired it up and booted. Works great. Sounds pretty great. I'm cranking it with 11 ohm speakers (which I know is outside recommendations) however that's just another temporary thing.
I'll take what I learned from my LCD project and then I need to find some kind of enclosure to put it all together in. Running LogitechMediaServer with Spotify Pandora and TuneIn Radio. I can probably slap a 1TB drive on here as well however if I do that I'll probably move to a Pi B+ or Pi 2. Might do that anyway.
Enclosure is either going to be antique radio or brand new shiny stereo modern enclosure. Whatever catches my imagination and eyes I guess.
Anyway, proof of concept is over. It works and is going to be perfect for what I have planned for it. Is this overkill? Yes. Do I care? No.
