But at 44.1k samples/sec, the requirements of a brick wall anti-aliasing
filter are so stringent that they, while controlling most of the aliasing,
introduce their own phasing artifacts. Going to 48k samples will result in
a filter with a considerable softer cut off, removing enough of those
artifacts and ringing from the filter so it makes sense that its going to
sound better, and that most ears can easily hear the diff in ABX testing.
