hi zanash, i think that he is going beyond a joke, just like in a T.T. you rely on arm settings, v.t.a. bias, tracking force etc, etc, transports are the main source of digital reading, also have a facility to sample to a resistance to inform the d.a.c. as much information that it can gather from the disc, then the d.a.c. on it's capebility to upsample the information it will deliver will have an output on analogue of it's own caracter"pending of who" but as we know the transport is, if not, the main key of digital source..nando
