Denon DVD-A1UDCI Blu-ray Player Reviewed

This $4,500 player is the crème de la crème of Denon's Blu-ray line, loaded with the company's high-end design and performance technologies. The DVD-A1UDCI is a universal disc player that supports Blu-ray, SACD, and DVD-Audio playback.

Denon's 2009 Blu-ray lineup includes three new models, ranging from an entry-level $499 player up to this reference $4,500 model. The top-shelf DVD-A1UDCI is not just a fully loaded Blu-ray player; it's a universal disc player that supports playback of the high-resolution SACD and DVD-Audio music formats (remember those?) and incorporates Denon's most advanced audio and video technologies. We have not performed a hands-on review of the DVD-A1UDCI, but here is an overview of the player's features. First and foremost, the DVD-A1UDCI is a Profile 2.0 Blu-ray player that supports BonusView/picture-in-picture playback and BD-Live Web functionality, and it offers both onboard decoding and bitstream output of Dolby TrueHD and DTS-HD Master Audio.

This player uses the Silicon Optix Realta HQV video processing chip, and the inclusion of Denon's AL32 advanced digital audio processing allows for the upconversion of 16-bit CDs to a full 32-bit digital format. Balanced stereo analog audio outputs are included, and the DVD-A1UDCI employs the new, fourth edition of DENON LINK in the HDMI connection. According to the company, when the player is mated with a properly equipped Denon receiver or preamp, DENON LINK 4th allows the master clock that operates the receiver or preamp's D/A converter to be transmitted to the player, so the devices share the same clock to virtually eliminate jitter. The DVD-A1UDCI does not support any type of video-on-demand streaming or download service, such as those offered by Netflix and Amazon VOD, and CinemaNow.

In terms of video connections, the DVD-A1UDCI offers dual HDMI outputs, as well as component video, S-video, and composite video outputs. Dual HDMI outputs allow you to send the A/V signal to two displays or to separate audio and video and send each via its own HDMI cable. This player supports both 1080p/60 and 1080p/24 output resolutions via HDMI, and it includes a Source Direct mode that allows it to output all discs at their native resolution. You can also output an HD signal via the HDMI and component video outs simultaneously. The setup menu includes an A/V Sync function, as well as a Vertical Stretch mode that removes bars from 2.35:1 sources, ideal for use with a CinemaScope screen and a projector with an anamorphic lens. The menu also offers numerous picture adjustments, including noise reduction, contrast, brightness, gamma, sharpness, chroma, and more.

The DVD-A1UDCI has the full suite of audio outputs: HDMI, optical and coaxial digital, and both 2- and 7.1-channel analog. As I mentioned, the dedicated stereo analog outputs are balanced XLR connections, and the DVD-A1UDCI is equipped with 32-bit D/A converters for each channel. The inclusion of multichannel analog audio outputs makes this model a good choice if you own an older, non-HDMI A/V receiver. The player has onboard Dolby TrueHD and DTS-HD Master Audio decoding, and it also passes these high-resolution audio formats in their native bitstream form over HDMI, for your A/V receiver to decode. High-resolution audio tracks from SACD and DVD-Audio discs can also be passed via either HDMI or analog audio. You can set the speaker size, crossover frequency, level, and distance for the analog outputs. The back panel also sports a proprietary DENON LINK port to employ the DENON LINK 4th feature described above.

The DVD-A1UDCI's disc drive supports the following formats: BD, DVD, SACD, DVD-Audio, CD audio, AVCHD, JPEG, MP3, WMA, AAC, WAV, and Divx. The back panel features an Ethernet port for BD-Live Web features, as well as quick firmware updates and IP control. The player lacks internal memory, so the addition of an external storage device is required to download BD-Live features; an SD card slot is provided for this purpose. The front-panel SD card slot also supports playback of JPEG, MP3, WMA, AAC, WAV, and Divx files. Finally, the DVD-A1UDCI sports both RS-232 and IR in/out ports for integration with an advanced control system.
