On the software side, it would be interesting to see what Audio Diff Maker had to say about the differences between a pre and post HDCD decoded file
(It has gain compensation, so should cope with the 6dB difference case)
^ Why not do it in software (hdcd.exe) via dbpoweramp or foobar? Then you won't need the box (assuming your DAC of choice can handle the resultant 20/24 bit files)
