It's not even necessity a "bad" device. Sometimes circuit designers add a DC blocking capacitor on an input to avoid damage to the equipment (especially in an high powered analog amp you might want to avoid feeding DC into the speaker).
The digital domain is much more forgiving; reason why I preach going all-digital up until I2S into the class-d amp IC :)
(No, I don't do that at home due to lack of available equipment - I'm still fully analog after the DSP/DAC combo).
