On the Bench
The bench tests for the O4HD were done with our standard set of CD quality, 16 bit, 44.1 kHz test tones played directory from the CD player in the O4HD. I also ran the same tests after importing the test CD into the O4HD which encoded the test tracks in FLAC format.
At 1 kHz, THD+N for CD played directly from the O4HD CD drive was 0.00126%.
At 1 kHz, THD+N for CD (FLAC encoding) played from the O4HD internal hard drive was 0.00125%.
Here are the results for 19 kHz, 20 kHz combined test frequencies for CD played directly from the O4HD CD drive. There is a small visible B-A peak at 1 kHz about 105 dB below 0 dBFS.

The IMD measurement for CD played directory from the O4HD CD drive was 0.0006%.
The IMD measurement for CD (FLAC encoding) played from the O4HD internal hard drive was 0.0007%.
