The ultimate integrated SA-CD/CD player — High-rigidity, high-precision
SA-CD/CD drive combined with exquisite disc tray and ultra-smoothloading mechanism. Ground-breaking MDSD (Multiple Double Speed DSD)
digital signal processing circuitry constitutes a moving average filter forstraight D/A conversion. Superior quality digital audio interface HS-Link.
When Accuphase introduced the ultimate separate-type
SA-CD/CD player, the models DP-800 and DC-801, a newepoch in audio history had begun. Garnering worldwide
acclaim both for their technological excellence and soundquality, the transport and processor pair has become thenew reference for SA-CD reproduction.
The new DP-700 is an integrated type SA-CD player
incorporating that very same state-of-the-art technology.
Major highlights are the ultra-rigid SA-CD/CD drive
assembly and the MDSD principle that takes the DSD
signal straight from the digital to the analog domain.
Latest digital signal processing technology is in evidence
throughout. Extensive series of listening tests wereconducted to shape the DP-700 into the world’s foremost
integrated SA-CD/CD player. As with all other Accuphase
players so far, a conscious decision was made notto support multi-channel formats but rather focus on
extracting the ultimate in musical fidelity from two-channel
SA-CD music sources.
In the transport section, a dedicated DSP chip controls
the digital servo to assure accurate readout of the signal
recorded on the SA-CD. Another vital aspect is thesingle-lens/twin laser diode pickup mounted to a highspeed positioning mechanism, providing a significant
improvement in read access times and accuracy. The
processor section features the innovative MDSD principle
forming a sophisticated moving average filter circuit,
together with the MDS++ D/A system that keeps conversion
errors to an absolute minimum and at the same time acts
as high-cut filter efficiently removing noise components
in the high frequency domain. The Direct Balanced Filter
provides separate low-pass filtering for the balanced andunbalanced signal paths, and the analog balanced output
circuitry eliminates interference during signal transmission.
The overall result is simply outstanding sonic performancethat removes the last veil from the music and beautifully
demonstrates what the SA-CD format is all about.
Internally, the transport and processor sections of theDP-700 are kept entirely separate. Digital inputs allow
independent use of the processor section for externalsources to enjoy music reproduction with the same superbquality.

HS-Link : High Speed Link
HS-Link is an ultra high-quality digital audio
interface developed by Accuphase using the latest
digital signal transmission technology. It supports
send/receive verification for copyright protection.
The LVDS (Low Voltage Differential Signaling)
principle allows a single dedicated HS-Link cable totransmit all audio data with utmost fidelity, including
2.8224 MHz/1-bit and 192 kHz/24-bit signals.

The DSD signal from the input is upsampled by a factor of2, resulting in a sampling frequency of 5.6448 MHz/1-bit.
After volume processing, the circuit performs D/Aconversion using a highly ingenious moving-averagefilter principle.
In the DP-700, this involves seven delay devices and eight
MDS++ type D/A converters. The signal is delayed (shifted)
progressively by one clock cycle to produce eight signals
which are sent to separate D/A converters for direct D/Aconversion. The converted signals are then summed.
Since conversion errors are kept to an absolute minimumby the use of MDS++ type DACs, the MDSD principle
results in an 8-pole high-cut filter with perfectly
linear phase characteristics.
