The audio signal is stored on CDs using PCM (pulse-code modulation), a digital method of storage.

A "transport" is a player that has an external digital output capable of sending the signal over a cable to a separate DAC. Since this CD player does not have an external digital output, it cannot be a transport.
I think you might have meant to ask if the player is a good "source." This implies that you're talking about the player as a package (transport + DAC) and listening to its analog outputs. If so, then the answer is probably not. 1-bit DACs are outdated and usually of low quality.
This model does have a optical output and can be used as a transport for an outboard DAC. It is also capable of outputing low level via RCA jack for a subwoofer also. this quite a nice unit for a "life style" receiver , only outputs 18w aside
