@jjss49 So it is like a car? 😎
The cartridge is literally a generator (motor).
The DAC is more like a graph paper to electrical plotting. And the ADC like the signal to the graph paper.
DAC is digital phono preamp and cartridge is the transport.
The DAC is probably more like the cartridge.
The phone stage is like the buffer at teh end of the DAC which outputs the signal.
And the RIAA is not in the ADC at all.
The transport would be like the TT itself, and if one has a streamer or a file based system,, then there is no transport.
