So now you're a cardiologist, eh? LOL, sorry, but that's now how it works.

This is because the noise is moved into areas where we can't hear it, leaving just the music.

The message is out of context 
deals with self dithering during the 24bit ADC process and truncation effects during requantisation and could be misleading if applied to our argument of 16bit. 
What goes into a DAC is a quantised digital datastream, what comes out has been converted into sine waves, that's why it's called a digital to analogue converter, duh!

an analog signal that has been digitized can be perfectly reconstructed if the sampling rate was 1/(2W) seconds, where W is the highest frequency in the original signal." (Wikipedia: NyquistShannon Sampling Theorum). 
Sorry, but this is wrong. No system with a finite bandwidth and a finite dynamic range can be other than finite. Continuous and infinite are not the same thing. A 16 bit DAC has a determined level of precision and infinite it cannot be, it may (or may not) do a perfect job of translating the supplied values into discrete voltage levels but it cannot for instance render a value represented as 1024.87654332 into a voltage as it cannot receive such a value.
