THD+N vs. Frequency showed that, regardless of the sampling, the CDP-502 performed beautifully. Most of the improvement is seen going from 16/44.1 to 24/96. Improvement between 24/96 and 24/192 in the audible band (20 Hz - 20 kHz) is not noticeable.
The frequency response was down 0.5 dB at 20 kHz, regardless of the sampling. But, with 24/192, there is a response far beyond the audible band, and for example, it is about 1 dB down at 30 kHz.
For a player as expensive as it is, the CDP-502 could stand for some improvement in its core video performance. Its de-interlacer performance is very good though, and the National Semiconductor AVC 2510 chip set handles most material very well, as there were really only a few minor hiccups it experienced in our DVD Player Benchmark™ tests. It would be hard for me to recommend the 502 based on its video performance alone, but people in the market for a player in this price class will undoubtedly be looking at it for its ultra high-end audio performance. That, combined with a robust video feature set and the ability to up-convert any material to various HD resolutions through HDMI, makes the CDP-502 an impressive offering overall.
