[QUOTE="pwatts, post: 891117, member: 146"] Extended frequency ranges in audio gear has less to do with psychoacoustics than with ensuring linear phase response and group delay. If the response cuts off at 20kHz with a sharp filter then there will already be filter artefacts lower in the audio band. Stretching the range helps to keep the audio band unaffected. [/QUOTE]
