There is absolutely no basis for believing that the filter cannot be
implemented without degradations in the audio band in high resolution
LPCM.

Roger Lagadec and the late Tom Stockham published a paper in the early
1980s showing, if I remember correctly, how the filter's pass-band ripple
was associated with time dispersion that could be audible.
