HDCD CDs and transcoding

[simoncn]

Is there a setting on the BDP-83 to enable or disable HDCD? If so, how do you have this set?

It could be that the HDCD decode plugin in foobar2000 (when constrained by 16-bit output) is adjusting the average level down as part of making a best effort to reproduce the original waveform with some compromise because the full 20-bit range is not available.
