World's First THX Ultra D V D Player
The DVD-5000 is a reference-class DVD video player featuring Denon's latest digital technology known as AL24 Processing which
produces the ultimate analog waveform fidelity to suit next-generation media. In order for AL24 Processing to perform at its maximum
potential, the DVD-5000 also incorporates a 4-DAC 24-bit D/A converter section which supports up to 96 kHz sampling.
With the Denon DVD-5000, the audiophile becomes enveloped in a digital sound of an order they have never experienced before. The
DVD-5000 is further equipped with HDCD decoding that has been combined with Denon's digital technology to bring out the highest
quality in sound that is possible with HDCD-encoded CDs. The DVD-5000 passes the strict THX Ultra specifications by Lucasfilm Inc.,
that have been established for best possible picture quality, audiophile sound quality and ease of operation.
