The Technology of Precision

The DP-1000 is the culmination of Accuphase’s 50-year pursuit of creating the idealtransporter. This high-rigidity, high-precision drive is equipped with a silent andelegant disc loading mechanism. The outer rotor brushless DC motor smoothly
rotates the disc, while the newly developed dampers protect the pickup fromvibrations. Incorporating a number of technological improvements like a low
center of gravity and fortified frame alongside features like programmableplaylists, the DP-1000 is the ideal transport to quietly and accurately read data.

■ Accurate Reading
Vibration countermeasures in SA-CD/CD playersthat read audio data from rapidly rotating discs
greatly impact sound quality. The DP-1000 uses ahighly rigid 7.2 kg (15.9 lbs) SA-CD/CD drive
mounted on a 3.8 kg (8.4 lbs) bottom plate tocreate a low center of gravity. This low center ofgravity construction prevents the housing fromwobbling while significantly reducing external
vibrations from reaching the traverse mechanism.
The traverse and disc loading mechanisms areinterconnected using high-quality elastic dampersof two different hardnesses to reduce the magnification of natural resonances in the objective lensand actuator, thus improving reading precision.

No mechanical contacts results in a highly reliablemotor with such low vibration and operating noisethat the quiet listening environment it creates will
make you completely forget that you are in thepresence of a rotating component.

The DP-1000 and theDC-1000 are connected
via an HS-LINK cable.
HS-LINK is Accuphase’s
original digital signaltransmission standard.
＊HS-LINK is a registeredtrademark of Accuphase
Laboratory, Inc.

Accuphase celebrates 50 years of manufacturing with the DC-1000, a digital processor
developed to deliver the ultimate in performance and sound quality. It is equipped with
the ES9038 PRO (ESS Technologies) processor: an 8MDSD (DSD signal) / 8MDS++(PCM signal) type D/A converter that drives 8 channels in parallel to deliver almost 3 times
more performance than single channel converters. Low-noise technologies refined during
development of the amplifiers, like amplification of ANCC and internal signals and parallel
arrangement of power circuits, allow the DC-1000 to deliver unprecedented levels of emotion.

Precision MDSD digital processor

The Technology of Precision■ MDSD (Multiple Double Speed DSD) principle
DSD signals contain a large amount of quantization noiseat frequencies higher than the range of human hearing,so digital filters have to be used to remove high frequency
noise. Typically, DSD signals are converted into PCM
signals before being input into the digital filter. The MDSD
principle employed in the DC-1000, however, generates 8
phase-shifted DSD signals and then inputs them to the 8channels in the MDS++ type D/A converter. The entire
circuit then operates as a moving-average filter withcompletely linear phase characteristics to eliminate highfrequency noise. MDSD represents a ground-breaking
playback method that does not convert DSD signals into
PCM signals, but instead operates as a filter thateliminates high frequency noise.

The MDS++ conversion principle is a revolutionary D/Aconversion method that employs multiple delta-sigma
type D/A converters connected in parallel for drastically
improved performance. By passing output from thehigh-performance ES9038PRO (ESS Technologies)
through 8 parallel converter channels, the DP-1000
provides a theoretical 2.8 (=√8) increase in overall performance for distortion, noise, linearity, and more. Because
the improvements provided by the MDS++ principle
are independent of signal
frequency and level, output
signal noise at very low levels
can also be minimized, a featthat conventional delta-sigma
converters find extremely
difficult to achieve.
