List of products by brand Accuphase

The name ACCUPHASE was adapted by taking the prefix ACCU from the word "accurate", and combining it with PHASE which is a most important factor in audio technology. We feel it is a very fitting brand name to describe our products that fully portray this and other important characteristics, which penetrate the innermost depth of audio technology. Our endless pursuit of quality requires a very high degree of processing which persuades us to avoid the use of mass production systems. Consequently, production volume is limited and Accuphase products are available only at a restricted number of specialized stores. Accuphase equipment is not subject to the whims of market fashion since they are made, above all, to achieve true high fidelity sound reproduction. This is the foremost reason why our products have enjoyed long-run production.

With a functionality level close to higher-end models and a versatile array of input and output terminals, plus the choice of adding option boards, the C-2150 provides fully immersive music enjoyment. This next-generation control center will satisfy even the most demanding music lover.

Accuphase C-2300 Precision Stereo Preamplifier

For more than half a century, Accuphase has continued its relentless pursuit of creating the ideal volume control circuitry. The C-2300 preamplifier utilizes Balanced AAVA – the successor of the AAVA system – to control volume without sacrificing vibrancy in the source sound. A newly added 4-band tone control enables fine adjustments to sound tone. Experience the sonic depth from the combined sound quality and superior features the C-2300 provides.

Accuphase C-3900 Precision Stereo Preamplifier

To celebrate the 50th anniversary of Accuphase\'s founding, the development of a new flagship model to incorporate the entire wealth of the company\'s experience was begun. Now, after five years, the work is complete. The C-3900 represents an uncompromising harmony of technology and sensibility, boasting ultimate performance and sound quality that ushers in a new era of the preamplifier.

The Dual Balanced AAVA design with two balanced AAVA circuits delivers sonic excellence that is transparence itself. Volume adjustment is realized while retaining all the vibrant energy and richness of detail that is the life breath of an artistic performance.

Accuphase C-47 Stereo Phono Preamplifier

The C-47 is the first phono amplifier of this series which realizes a fully balanced configuration from input to output. The resulting product not only is highly impervious to external noise, it also features a dedicated head amplifier optimized for the characteristics of MC and MM phono cartridges, and a high-accuracy equalizer amplifier, thereby ensuring precise equalization with a minimum of noise. A set of newly added dedicated balanced MC phono inputs enables balanced connection to the analog record player. By bringing out the full performance potential of each phono cartridge, the C-47 delivers a rich and deeply satisfying musical experience.

Accuphase DAC-60 Digital Input Board

The DAC-60 is a digital input board that can input digital signals directly into amplifier units when installed in Accuphase preamplifiers and integrated amplifiers (listed below). Three input types are provided (USB, OPTICAL, COAXIAL) for connection to a broad range of digital devices.

Accuphase DC-1000 Digital Audio Processor

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

Accuphase DF-65 Digital Frequency Dividing Network

The Digital Frequency Dividing Network DF-65 harnesses the very best of digital technology in every aspect, including a high-speed 40-bit floating point DSP. The standard unit configuration supports signal processing for up to four-way systems. Highly accurate digital filters offer a choice of 59 cutoff frequency points and up to 96 dB/octave attenuation. Integrated time alignment function adjustable in 0.5-cm steps, and delay compensator for automatically offsetting any filter circuit delays. Monophonic output mode provides high versatility for various configurations.

Accuphase DG-68 Digital Voicing Equalizer

Since launching the revolutionary DG-28 in 1997, the DG series, which combines sound field correction (Voicing) and sound field creation (Equalising) functions, has been pursuing the ease of use and high electrical performance. DG-68 is a successor of DG-58, released in 2013, adopting the latest devices and further improving AD-DA conversion accuracy.

In VOICING mode, the DG-68 measures room acoustics accurately and eliminates extreme dips and peaks such as standing waves. This improves the localisation of vocals and the expansion of  sound stage dramatically. In addition to automatic adjustment of   target characteristics, it is also possible to draw desired target curve in the manual mode or to correct room acoustics according to the customer’s own loud speakers.
