On the Bench
The Marantz UD9004 had solid performance in nearly all of our benchmark tests. Measurements were taken at 1080i resolution with our Tektronix Oscilloscope from the component analog video outputs. The UD9004 had excellent results in our core tests and were very similar to the results we saw with Denon's DVD-A1UDCI universal Blu-ray player. White levels were measured at a very respectable 99.3IRE, luma and chroma channels were in perfect alignment with each other, and the image was displayed in full resolution without any cropped pixels. As you can see in the graph, the frequency response measured from the UD9004 is very close to being ruler flat which translates into exquisite picture quality.
In our HD section of the benchmark the UD9004 had solid performance. The player passed our tests for banding, 1920x1080 pixel cropping, and since the UD9004 is a motion adaptive player it was able to apply diagonal filtering. There was some material where I could observe some slight stair stepping but it was minor and wasn't enough to prevent the player from passing the diagonal filtering test. One area where the UD9004 fell short was in its 1080i/p conversion. While the player can handle 3:2 cadences, it doesn't convert the 2:2 cadence properly and some artifacting can be observed. The most common type of real world material of this cadence would be in 1080i concert or documentary footage.
Standard DVD Performance
When Blu-ray was first making its way to market, most players didn't offer good standard DVD performance as well as Blu-ray performance, but this trend has changed with companies such as Denon, Pioneer, and Oppo creating players that serve both purposes quite well. Marantz can be added to that list now as the UD9004 had perfect performance across the board on our standard DVD benchmarks. The UD9004 passed every one of our film based cadence tests using both HDMI and component video connections.
On video based material the UD9004 passed every test and showed that it is motion adaptive, features diagonal filtering, and is able to switch between film and video with good recovery time.
In addition, the UD9004 passed all of our chroma upsampling tests with flying colors.
The only area where the UD9004 fell short was in its usability. Responsiveness was a little on the sluggish side and the layer change measured at nearly one and a half seconds.
Using 19 kHz and 20 kHz sine waves as the test signal, the B-A peak at 1 kHz is nil, which is excellent.
The measured frequency response was ruler flat to 20 kHz.
IMD, using 60 Hz and 7 kHz sine waves, was only 0.0023%.
A 1 kHz sine wave test signal resulted in 0.003% THD+N, again, excellent performance.
