Integrated SACD/CD player with HS-Link. Ready for new-generation formats such as
2.8224 MHz/1 bit and 192 kHz/24 bits. Revolutionary MDS (Multiple Delta Sigma) converter. T ransport section with dedicated DSP for digital ser vo control and single lens/twin
pickup high-speed access mechanism. Entirely separate construction of transport and
processor sections, with HS-Link and coaxial transport output and digital inputs.
The Super Audio CD (SACD) is now the pinnacle
format of pure audio. Based on the expertise
gained with the separate type SACD/CD play er
combo DP-100 and DC-101, Accuphase
developed the DP-85 using the latest advances
in digital technology . The result is an integrated
SACD/CD player of the highest quality. The
DP-85 lets you fully enjoy the amazing dynamic
range of SACD/CD sources. The superb sound
quality is sure to capture the heart of any
audiophile.
The transport section of the DP-85 features a
dedicated DSP for the digital servo circuitry and
a single lens/twin pickup high-speed mechanism
for totally accurate signal readout and almost
instantaneous access time. The processor
section is ready for the latest word in quality
such as 2.8224 MHz/1-bit and 192 kHz/24-bit
sources. The MDS (Multiple Delta Sigma) D/A
converter employs multiple strictly selected
delta sigma units in a parallel configuration,
assuring unprecedented conversion precision.
Although housed in one enclosure, the SACD/
CD transport section and the processor section
of the DP-85 can be used entirely independent
of each other, thanks to the HS-Link and coaxial
outputs and the digital inputs. Slots for option
boards are provided as well, resulting in
unsurpassed versatility for no-compromise
reproduction of music. The DP-85 represents
digital audio at its best, allowing the audio
connoisseur to rediscover what music is all
about.

Connection examples for effective use of SACD/CD transport
The HS-Link output of the transport section can be used to combine the unit with a DC-330, DC-101, DG-28, etc.,
using dedicated HS-Link cable. With the DC-330 → DF-35 combination, a multi-amplified system entirely in the digital
domain can be constructed.

Using the HS-Link, it is possible to keep the connection of DP-85 → DC-330 → DF-35
entirely in the digital domain until directly before the power amplifier. The various components
are connected with HS-Link cable.

New Generation Digital Interface
HS-Link: High Speed Link
HS-Link is an ultra high-quality digital audio interface developed
by Accuphase using latest digital signal transmission technology .
It supports send/receive verification for copyright protection. The
L VDS (Low V oltage Diff erential Signaling) principle allows a single
dedicated HS-Link cable to transmit signals using advanced
formats such as 2.8224 MHz/1 bit or 192 kHz/24 bits. Conv entional
digital formats are also supported. Because digital audio data
are transmitted with utmost fidelity , the sound quality achieved b y
HS-Link is simply outstanding.
