** What a load of ********.

The CD format was designed to record and reproduce MUSIC with no audible loss of quality compared to the original signal.

The format will reproduce signals containing frequencies up to 20kHz with no change.

With MUSIC signal, extensive testing showed that no-body could hear components beyond that frequency.

That some young people can detect steady tones above 20kHz, when reproduced at a high enough level, is irrelevant.
