I’ll take this one.
Vinyl doe not have “effectively infinite bitrate.” All sound reproductions introduce error, including analog. The question is: What •kind• of error? How much?
In the case of digital, much of the error comes in the form of •quantization noise•: the difference between the “stair step” shape of digital and the actual signal. (Good image of it here: http://davidswiston.blogspot.com/2014/11/adcs-dithering-when-adding-noise-is.html) There’s also some error that comes from circuitry etc. 1/
