KORG DS-DAC 100

Description

The KORG DS-DAC 100 is a distinctive and stylish USB Digital-to-Analog Converter (DAC) and headphone amplifier, known for its focus on high-quality DSD (Direct Stream Digital) audio playback. Its unique, elliptical "spaceship" design sets it apart visually, while its internal components are geared towards delivering a clean and detailed sound, particularly with DSD audio sources.  

The DS-DAC 100 supports native playback of 2.8224 MHz and 5.6448 MHz DSD files, leveraging KORG's expertise in DSD recording technology from their acclaimed MR series recorders. It also handles PCM audio formats up to 24-bit/192kHz. A key feature is its ability to perform real-time DSD conversion of PCM files using the included KORG AudioGate 3 software (or later versions). This utilizes the processing power of your computer to upsample PCM audio to DSD for playback through the DAC.  

The hardware design emphasizes low jitter, employing asynchronous USB transmission where the DAC clocks the audio data from the computer. The D/A conversion is handled by a Cirrus Logic CS4398 chipset, a well-regarded component known for its performance. The unit is USB bus-powered, simplifying connectivity by eliminating the need for a separate power supply.  

Connectivity options include a single USB input, unbalanced RCA line outputs, balanced XLR line outputs, and a front-mounted 1/4" headphone jack with a dedicated volume control. The front panel also features LED indicators for power and the sampling frequency of the incoming digital signal.  

The KORG DS-DAC 100 is often praised for its smooth, detailed, and controlled sound, especially with DSD content. While some reviews note that its performance with standard PCM files might be matched or slightly बेहतरed by similarly priced rivals, its strength lies in its ability to deliver high-fidelity DSD playback and its unique design. The requirement of the AudioGate software for optimal DSD upsampling is a point to consider for users who prefer other playback software. Key Features:
