Is a DAC still needed?


Most CD players manufactured these days have good quality built-in DACs. Would an external DAC then becomes unneccesary?

Yes and No.

It depends upon what you want from your source. Not all CD players will have the ability to stream music from a computer or play the same types of discs. Some are more universal than others. The type of chip-set will vary as will jitter control, noise floor, reputation, etc.

You should map out what you want from a player and the types of files you will likely listen to and the the connections needed to accomplish that. (CD, CD-R, SACD, HDCD, Flac, WAV, Internet Radio, iTunes, USB media, Ethernet etc.) upsampling, No-Oversampling, Hi ReZ.

There is a lot to consider isn't there?
If your internal DAC is better than the outboard, no. It probably doesn't matter how expensive your player is, someone may find a more expensive outboard DAC for it. But better sounding? Like Rrog said, it depends on your player. Then like Tom6897 said, there are other sources that could use one.
