I've bought a Pimoroni PHAT DAC for my Raspberry pi zero and despite weeks of searching I can't find a definitive answer on whether I need to get an amp breakout board too like this guy http://frederickvandenbosch.be/?p=1447 (although he's using it to convert the signal to mono and I'd like to keep stereo) to build an Internet radio.
Do I need a https://shop.pimoroni.com/products/adafruit-stereo-3-7w-class-d-audio-amplifier or will the PHAT DAC be enough to power speakers soldered directly to the DAC?
