Accuphase DC-901 D/A Converter The DC-901 showcases Accuphase’s mastery of sophisticated digital technology and creative circuit topology. It is a digital processor designed to bring out everything the SA-CD format has to offer. A new technique called MDSD allows straight D/A conversion of the DSD signal. Multiple DSD signals delayed through digital processing in an ultra-high-speed FPGA are converted by separate D/A converters. After D/A conversion, summation of the multiple data is performed, resulting in an ingenious moving-average filter circuit with double-speed accuracy. An important characteristic of MDSD is the use of MDS type D/A converters which keeps conversion errors to an absolute minimum. At the same time, the MDSD circuit acts as a high-cut filter with completely linear phase characteristics. The end result is a digital signal of outstanding quality, allowing the music to emerge in perfect clarity, demonstrating the ultimate potential of the SA-CD format. Ultra-high-speed FPGA harnesses digital processing power to implement innovative MDSD reproduction with double-speed high-precision moving-average filter circuit.Sixteen MDS type D/A converters driven in parallel. Each channel uses two Hyperstream™ DAC chips (ES9018) in parallel.“Direct Balanced Filter” performs totally separate analog low-pass filtering for line and balanced signal paths.D/A converter printed circuit boards made from glass fluorocarbon resin with low dielectric constant and low loss.EXTERNAL DSP input/output connectors (HS-LINK and optical) allow insertion of DG-58 in signal path.Seven digital inputs: HS-LINK, balanced, coaxial (2), optical (2), USB.Coaxial and optical digital outputs.Line and balanced analog outputs.

Accuphase DC-37 D/A Converter 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 DC-37 is a digital processor that redefines the state-of-the art and has its sights firmly set on the future, including computer-based and high-resolution audio. Only strictly selected circuit components, materials and other parts of the highest quality are used, resulting in an immense richness of information that translates into a spectacular musical experience.MDSD type D/A converter using eight parallel circuitsDirect Balanced Filter with totally separate line and balanced signal pathsSupport for 5.6448 MHz (1-bit 2-channel DSD) and 384 kHz (32-bit 2-channel PCM)Six digital interface inputs including HS-LINK and USBPhase selector for balanced outputsSampling frequency and quantization bit display for input signalSeparate power transformers for digital and analog sectionsAccessoriesUser manual(jpn), Remote control, RCA cable, CD-ROM, Power cord, original boxPower supply voltageAC100V 50Hz/60HzOther informationDimension: W465×H114×D385 mmWeight:14.4kgReleased year:2014*Import duties, taxes and charges are not included in the item price or shipping charges.
