Accuphase DP-78 Brochure

An SA-CD/CD player of the highest order Processor section supports highquality formats such as 2.8224 MHz/1-bit and 192 kHz/24-bit. Further improved MDS++ D/A converter. Transport section features dedicated DSP for digital servo and single lens/twin pickup high-speed access mechanism. Separate construction of transport and processor sections and respective connectors allow independent use. HS-Link input/output boards available as option.

The Accuphase separate type player combo DP-100 and DC-101 incorporating HS-Link connectivity is recognized both in Japan and overseas as the ultimate setup for SA-CD playback. It is the standard against which all others have to be measured. And now, the superior technological know-how gained through the development of this combo has found another manifestation in the integrated SA-CD/ CD player DP-78. Incorporating the latest advances in digital technology, the DP-78 is destined to take its place at the top of its class. By concentrating solely on twochannel sources both in the SA-CD and CD format, the DP-78 lets you fully enjoy the best that orthodox music reproduction has to offer.

Ever since its introduction in 1999, the SA-CD catalog of hybrid discs has been expanding. With its 2.8224 MHz/ 1-bit format, the SA-CD stores four times as much information as a conventional CD at 44.1 kHz/16-bit. This allows it to realize dramatically superior physical performance as manifested by wider frequency response and dynamic range. The DP-78 is equipped to make full use of this impressive potential. It will let you rediscover the deep joy and satisfaction that a truly outstanding musical experience can offer. But the DP-78 not only handles the SA-CD format with impeccable finesse, it will bring out the best from conventional CD sources as well. Be prepared for a wholly new encounter with your entire musical catalog.

Transport section outputs

Connection example for effective use of SA-CD/CD transport

The SA-CD/CD transport section and the processor section of the DP-78 are kept entirely independent of each other, to achieve optimum performance in each regard. The transport features a single lens/twin pickup high-speed access mechanism, combined with a digital servo controlled by its own DSP. This advanced approach assures highly accurate processing of the digital signal and excellent support for high-sampling-frequency sources including 2.8224 MHz/1-bit and 192 kHz/24-bit. The DAC a key component for determining sound quality incorporates a further refined version of the acclaimed MDS principle, called MDS++. As a result of this non-holds- barred approach, the DP-78 projects a sound stage of unprecedented realism and sheer musical perfection.
