How does the HiFiBerry DAC/DAC+ affect sound quality?
DigitalToys.info tested the sound quality of the Raspberry Pi in combination with HiFiBerry DAC/DAC+. Their conclusion:
“Whoever puts a little more value on good sound, has to go for a high-quality DAC. The HiFiBerry family proves, that you can inexpensively and quickly turn the Raspberry Pi into a high-quality audio player with their boards.”
The whole test and more results (in german) can be found here. Note that there is some kind of problem in their measurement setup as the frequency response of the HiFiBerry DAC is flat. There is no decline in volume starting at 600Hz as shown in their graphs.
