On the Bench
THD+N measurements were within an 80 kHz bandwidth. Sine waves were generated at -5dB and burned to CD (16/44.1) or DVD-A (24/192) for playback on the Oppo.
At 1 kHz, using a 16/44.1 sampled 1 kHz sine wave, THD+N was 0.08%.
Using a 24/192 1 kHz sine wave, distortion dropped to 0.008%. So, at the high res rate of a DVD-A, THD+N is only 10% of what it is at 16/44.1 redbook sampling. That is a pretty clear indication that DVD-A is worth having in our recordings.
At 10 kHz, distortion was at 0.5%, using 16/44.1 sampling.
While at 24/192, a 10 kHz sine wave resulted in 0.013% THD+N. Again, it is much lower with the higher sampling rate.
For IMD, the results were a little different.
At 1 kHz, 16/44.1 sampling, IMD was 0.014%.
And with 24/192 sampling, it was less, but insignificantly so.
For frequency response, at 16/44.1 sampling, the response was down 0.2 dB at 20 kHz.
While at 24/192 sampling, the response was down 0.1 dB at 20 kHz. Both results (16/44.1 and 24/192) are good.
The player is due to be released on March 10, 2008 (next week). If you would like to see what the instruction manual looks like, you can download a PDF here.
While it is likely we will all be using HDMI from our DVD players to send both audio and video to our SSPs or receivers in the near future, measurement of the analog performance of players is still an indicator of build quality, and the Oppo DV-983H is excellent in this regard.
