As far as I know this is not an "of the shelf" property.
Inherent to the loudness war are inter sample peaks that can exceed 0 dBfs.
Benchmark media found out that with their collection of CDs this can run as high as +3.5
They decide to use the internal volume control of the Sabre DAC to reduce the level by default with -3.5.
