Product Features

The Accuphase DC-37 is a top-of-the-line digital preamplifier with exceptional performance and versatility. It has a highly precise MDS++ D/A converter as well as advanced digital signal processing capabilities such as upsampling and re-clocking. The DC37 also has an easy-to-use interface with a large colour display and simple controls. It also has a variety of connectivity options, including USB, Coaxial, Optical, and AES/EBU inputs. The DC-37 is easily integrated into any high-end audio system and produces a transparent, detailed, and natural sound quality that audiophiles and music enthusiasts adore.

Exceptional technology
The Accuphase-DC-37 employs cutting-edge digital technology to deliver unrivalled sound reproduction. It makes use of an ultra-precise clock generator for low jitter and high-precision D/A conversion, as well as advanced DSP algorithms for digital filtering and equalisation. A high-performance analogue output stage with discrete components and a power supply with large-capacity capacitors complement the unit's advanced digital processing capabilities.

D/A converter of the MDSD type
The Accuphase-DC37 is equipped with an MDSD (Multiple Double Speed DSD) type D/A converter that uses four DAC chips per channel to support a wide range of digital signals, including PCM and DSD. This high-precision converter uses a proprietary digital filter and a clock generator to reduce jitter and other digital noise. As a result, the original source material is reproduced with exceptional accuracy, detail, and natural sound reproduction. One of the key technologies that distinguishes the Accuphass- D-C-37 from other digital processors on the market is the MDSD D/A converter.

Balanced Direct Filter
The DC-37 Accuphase incorporates a Direct Balanced Filter for high-precision signal processing. This filter can process both balanced and unbalanced signals with minimal distortion and noise. The filter's superior signal processing capabilities are ensured by the use of a high-speed FPGA and high-precision calculation technology. The Direct Balanced Filter also removes any phase shifts, ensuring that the original signal is accurately reproduced.

The frequency of sampling
The DC-37 -Accuphase supports a wide range of sampling frequencies, ranging from standard CD and DVD sources to high-resolution formats like DSD and PCM up to 384 kHz. It also has an asynchronous USB interface with up to 32-bit/384 kHz PCM and 5.6 MHz DSD support. This enables the DAC to reproduce the entire spectrum of music with high precision and fidelity. Because of its ability to handle a wide range of digital signals, the DC 37 is a versatile and powerful tool for any audiophile or music lover.

Power transformers on their own
The DC-37-Accuphase has separate power transformers for its analogue and digital circuits, which helps to reduce noise and interference between the two circuits. This allows the D-C37 to produce cleaner, more detailed sound. The analogue section transformer is of the toroidal variety, whereas the digital section transformer is of the EI variety. The power supply section also includes large filtering capacitors to ensure a stable and noise-free power supply, which contributes to the DC-37's high performance.

Conclusion
The Accuphase DC-37 is a top-of-the-line digital processor that represents Accuphase's technological pinnacle. The MDSD D/A converter, Direct Balanced Filter, and separate power transformers all work together to produce exceptional sound quality with great clarity and detail. It is simple to use thanks to the high-resolution display and intuitive controls, and the wide range of digital inputs and outputs ensures compatibility with any system.
