content: Let me deconstruct this: you have an analogue source signal converted to a digital approximation. You convert it back to analogue in the form of a vinyl cast. You then drag a sharp rock through the grove that vibrates a pair of magnets through a coil of wire. You then pass this small signal through multiple stages of RIAA correction and amplification. You then convert the signal back to mechanical motion via a coil of wire and another magnet. Wow! Not much room for distortion in that chain.
