From my understanding, CD players/multichangers can be used 1 of 2 ways. 1) As a transport. 2) As a player utilizing it's own internal DAC's. As such, this basically means that by using digital interconnects (optical or coaxial) between the CD player and the receiver/preamp, the CD player is thus qualified as a "transport." If, on the other hand, the CD player is connected via analog interconnects (RCA or XLR), then you will be utlizing the CD's own internal DAC's. This being true, and I don't know if it is, but wouldn't that mean no matter what level a CD player is ($60-$25,000), connecting it with a digital cable would make it all sound the same, since all signal processing would be taken charge of by the receiver/preamp? Becaues if that's the case, why would ANYONE with a high-end CD player use it as a transport? Wouldn't they simply be better off using the CD player's own, internal circuitry to produce sound? And along these same lines, wouldn't that mean any DVD player, SACD player, or DVD-A player connected with a digital cable produce the same results? Identical sound compared to another player connected to the same receiver/preamp?? I am really quite confused on this subject, and if someone can shed a little light on it I'd be much obliged.
