The DC-37 inherits the outstanding technology of the DC-901 and DP-720, while opening a new chapter in ultra-advanced and innovative digital signal processing technology. It features an MDSD type D/A converter that achieves straight conversion of the DSD signal and supports 5.6448 MHz (1-bit 2-channel DSD) sources. In keeping with this development, the HS-LINK interface has also been upgraded to Version 2 with significantly expanded sampling frequency and quantization support up to 5.6448 MHz (1-bit 2-channel DSD) and 384 kHz (32-bit 2-channel PCM). The DC-37 also offers convenience and flexible functionality. External digital sources can be connected via a total of six digital inputs: HS-LINK, COAXIAL 1, COAXIAL 2, OPTICAL 1, OPTICAL 2, and USB.
The new A-36 inherits many of the outstanding design technology features developed for the higher-end models. It redefines the baseline for pure class A power amplifiers and represents the same unwavering attention to detail and dedication to sound quality for which Accuphase is justly famous.
In the output stage, power MOS-FETs renowned for their excellent frequency response, sonic performance, and superior reliability are used in a triple parallel configuration and driven in pure class A. This is sustained by the strong power supply featuring a massive transformer and two large 47,000μF filtering capacitors. Output power in each channel is rated for an impressive 150 watts into 1 ohm, 120 watts into 2 ohms, 60 watts into 4 ohms, and 30 watts into 8 ohms.
The centerpiece of the DP-950 is its ultra-massive SA-CD/CD drive with highly rigid, high-precision construction. This is complemented by an ultra-strong power supply featuring two high-efficiency toroidal transformers and an array of filtering capacitors. The result is an SA-CD/CD transport that delivers a digital signal of unsurpassed purity.
Newly designed next-generation SA-CD/CD drive combined with exquisite disc tray and ultra-quiet disc loading mechanism for silky smooth operation. Innovative MDS+ type D/A converter using four parallel DAC circuits ensures highly accurate D/A conversion of DSD and PCM signals. Separate configuration of transport and processor sections, each equipped with a set of HS-LINK, coaxial, optical, and USB (input only) connectors. USB connector provides support up to 384 kHz/32-bit and 11.2896 MHz/1-bit DSD.
The Accuphase-developed high-rigidity, high-precision drive optimized for CD reproduction, along with a super-quiet and smooth disc loading mechanism ensure pure signal readout of the highest order. In the processor section, the MDS type D/A converter utilizes four DAC chips driven in parallel, and the filter amplifier features the newly developed ANCC (Accuphase Noise and Distortion Cancelling Circuit). CD transport section and digital processor are kept completely separate. In addition to a USB input, coaxial and optical connectors are provided for digital input and transport output. Quality construction and highly advanced digital technology fully reveal the potential of the CD medium and provide a listening experience that opens up new emotional depths even with familiar music sources.
The new Precision Stereo Preamplifier C-3850 continues the challenge and raises the bar even further, bringing together the entire wealth of preamplifier know-how gained by Accuphase over the years. In construction as well as circuit design, it incorporates latest technology realized with components selected through a thorough review process including extended listening tests. The result is an audio instrument that admits no compromise in the pursuit of peerless performance for musical mastery.
The C-3850 features a further evolved version of this principle, called "Balanced AAVA", with two AAVA circuits driven in a parallel balanced configuration.
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.
Quiet and ultra-smooth disc loading mechanism combined with a high-rigidity, high-precision SA-CD/CD drive extracts the full scope of the recorded information. The innovative MDSD (Multiple Double Speed DSD) D/A converter comprises eight MDS++ devices driven in parallel and a moving average filter to recreate an analog signal of stunning purity. The versatile array of transport outputs and digital inputs enables connection of a voicing equalizer or other equipment in the digital domain. Harnessing the latest technology in a masterful ensemble, the DP-750 goes straight to the heart of the music.
Every audio component draws all of its energy from the power supply which in turn is connected to the AC power grid. The Clean Power Supply components from Accuphase are products that remove noise and impurities from the AC power line through a groundbreaking new approach, resulting in a drastic improvement of the sound and picture quality of connected audio and video equipment. Without relying on an oscillator, the reference waveform is created with further improved accuracy and is linked to the power section by a balanced connection to ensure incredibly low distortion in the output waveform. Because the PS-1230 can deliver as much as 1200 VA (1000 VA), it covers the requirements of almost any high-quality A/V system currently on the market.

Blending the purely analog AAVA volume control circuit with sophisticated technology inherited from the C-2850 results in superb S/N ratio and a refinement of expression that brings new clarity to the music. The utterly smooth operation feel of the volume sensor assembly and a top plate made of brushed aluminum with a hairline finish demonstrate a level of dedication and hands-on craftsmanship that pervades every aspect of this preamplifier. Each C-2450 is individually honed to provide nothing short of perfection.
The E-380 realizes a 20% increase in rated output power thanks to a reinforced power amplification stage and power supply. The further evolved AAVA volume control system allows music enjoyment at any level without even the slightest degradation of signal quality. The power amplifier section utilizes the instrumentation amplifier principle to achieve outstanding S/N ratio. Low impedance design of the output circuitry results in a damping factor of 500, ensuring that the potential of every speaker can be brought out to the fullest. Enjoy a musical performance of amazing transparency and dynamism.
Digital signal processing is implemented through an ultra-high-speed FPGA in conjunction with innovative MDSD reproduction technology, forming a double-speed high-precision moving-average filter circuit for straight D/A conversion of the DSD signal.
