The site you linked to talks about why a higher sampling rate then what cds use is unnecessary. However, lossless audio (a different thing) is always good and is supported in DVDs, Blurays, and Cds. Lossless audio is often indistinguishable from compressed audio but is usefully when rencoding to a lossy format. (lossy to lossy will produce noticeable quality loss) Flac is a good thing and is supported by the MVK container.
