I bought this DAC for connecting a Raspberry Pi (use as salon music player with mpd MPDroid + Controller) Model B to my HiFi amplifier. The output jack of the Raspberry Pi was poor and caused an audible snoring in pregnant With the DAC RCA output is quiet (no humming or breath when the volume of the amplifier is maximum) and audio quality is limited by that of MP3 files / flac. In short perfect for the price.
