We all know that the built-in audio of the Pi has poor quality, and that the usual way to deal with that is to use:
Raspberry Pi -> DAC -> amplifier -> speaker or headphones
Queston: does the solution "digital amplifier" work as well? Is the quality as clean as a DAC? Example:
Raspberry Pi -> MAX98357A -> speaker or headphones
The Adafruit board you've linked to is just a DAC and amp bundled together. From your linked page:
It takes standard I2S digital audio input and, not only decodes it into analog, but also amplifies it directly into a speaker.
I've tested most of the audio output options from the Pi, and pretty much everything aside from the analogue output is OK. I've encountered some instances of interference when using an HDMI to analogue converter, but nothing in the same league as the 3.5mm jack output.
