Denon DVD-A1 (1999)
The Denon DVD-A1 was one of the first DVD players to support the then-new DVD-Audio format. Denon built it to make a statement. It was based on the company's earlier DVD-9000 player and positioned as the flagship of the early DVD lineup, a reference-quality machine for home theater people who cared about both picture and sound.
On the video side, the player used a 10-bit/54 MHz video D/A converter. For audio, it carried 24-bit/192 kHz D/A converters on all channels, with dual DACs dedicated to stereo playback. It also had a built-in Dolby Digital and DTS decoder with 5.1 channel analog output, plus a "pure direct" mode that disabled the video circuits for audio-only listening. The chassis was rigidly built to reduce vibration, a priority carried over from Denon's high-end audio components.
Connectivity was generous for the era. It had component, S-Video, and composite video outputs, coaxial and optical digital audio outs, stereo and 5.1-channel analog outputs, and an RS-232C port for custom installation. It accepted DVD-Video, DVD-Audio, Video CD, and CD (including CD-R/RW). The transport was specifically engineered to handle DVD-Audio discs with precision, since the format was brand new at the time.
Period coverage is thin. Audio (October 1999, p.231) ran the DVD-A1 in an equipment roundup, though the surviving scan is fragmentary. Later enthusiast reviews say more. Audioholics called its video and audio performance reference-quality, and Home Cinema Choice described it as a serious player for serious home theater enthusiasts. AVForums members praised the build - "it's a tank" - while noting the unit is heavy, bulky, and has a user interface that feels dated by modern standards. Loading times were also slow compared to later players.
Some things are not documented. There is no original price, no production end year, no dimensions or weight, and no measured performance data (THD, S/N ratio, frequency response) in the sources available.
