- Q: Can you hear the difference between CD-quality lossless audio and anything higher fidelity? A: No, no one even has the biological ability to. 44100khz, 16-bit audio can perfectly reproduce audio as far as we can physically tell. The only reason to store anything higher is for production or archiving (that is, for computers to listen to).
- Q: Can you hear the difference between 320kbps MP3 or the equivalent, and CD-quality lossless? A: Yes, this is _theoretically_ possible. However, many well-controlled listening tests have been performed on this subject that all say no, so it's much more likely that you can't, and the burden is on you to prove otherwise with an abundance of evidence.

The listening test linked in the article leads nowhere, I would have liked to see their methodology.
