CD players generally do a pretty good job of that. If you stick to mainstream recordings in mainstream formats, you are pretty safe.
I've seen a few where the filter that is supposed to cut out the delta-sigma noise was pretty weak, and a couple DAC's that had 300+kHz tones leaking out. This is, to use a very simple term, "unacceptable".
I have yet to know where the tones came from. But there's an example of something that needed to be filtered out.
