I'm looking for perfect audio DAC for ESP8266/ESP32

At one point I've decided to create ESP-32 based web-radio in the case of old classic radio. 

This one I've bought for around 50 euros, it wasn't working obviously, and frankly  didn't bother to fix it. From one point I'm not a big fan of AM, from the other it has a very peculiar schematics, it runs from mains directly without input transformer of any kind. If you push the socket in the "right" direction all metal parts will be live, so decided I wouln't want to have that anywhere in the house near children playing with screwdrivers.

Going back to the project. I've forked Ka-Radio32 repo, which is a ready to use wifi radio project. What I needed to do is to add HW definition of my board, and more importantly add TAS5805 amp support, since this is the amp I have on the board. 

With that done it is relatively easy to fins some space within the box for new board and remote control receiver. Also I've connected power-on switch from the radio itself, and put IR receiver under the front panel

And the final result is below.

That's a cool retro radio case that you've given new life to. 👍 I can even read the type of the vintage pentode, UF80, 100mA heater for series connection.
