DAC as an upgrade

My CD player (Denon cdrw1500) has both coaxial and optical digital output jacks.

I'm wondering if there are any issues to be concerned about with using this with a separate DAC unit rather than the Denons built in DAC.

I'm thinking that this would be a practical first step to explore the advantages of different DAC technologies with my player for now and then even provide the option to add a separate transport if needed later.

I am not very familiar with digital connector technology commonly used in audio equipment these days, so I am mainly concerned to know what DAC digital interfaces are compatible with the the Denon outputs and the differences if relevant so as to identify a DAC that will work OK.

Thanks.

Cerrot,

Thanks for the explanation. Very helpful.

So my next question is what are some good upsampling DACs out there these days to consider as an upgrade to whats on-board the Denon and what do they sound like, if possible to explain?

Mapman - Many DACs these days have built in jitter reduction circuitry allowing to use anything as a transport. I use Benchmark DAC1 with sony DVD player using 75 Ohm coax. Toslink connects my TV to Benchmark and I have still have one more unused digital input left. Since Benchmark has volume control I have it connected directly to power amp. This arrangement allows me not only to listen to TV but also to DVD, play MP3 (inherent in DVD players) and eliminate preamp+ICs. If you decide to built your own coax use quality cable like Canare, keep distance to minimum and obtain 75Ohm RCA connector (standard are not). Most likely you will have RCA on one side and BNC on another.
Check also Bel Canto DACs - warmer presentation (not to my taste).

Audition the DAC(s) in your system before you purchase. You may be surprised at how little difference you hear. I don't know how old your Denon is, but many of today's CD players utilize excellent DACs. Do use a 75 Ohm digital coax cable (Stereovox XV2 is very good for the money). I would recommend including the PS Audio DL3 on your short list.
