SOUND WARRIOR USB DSD Audio To Analog Made In High-Performance D/A Converter, High-Resolution Compatible, USB/Coaxial/Optical Converter, Japan,

[Important Notice] We have discovered that the USB audio transfer method "Bulk Pet" included with the SWD-DA15 does not work on macOS Tahoe. We are currently investigating a solution. Future information will be posted on the SOUNDWARRIOR website and on social media. Mac users who do not use the Bulk Pet function do not need to install the Bulk Pet driver, and updating to macOS Tahoe will not affect operation. Enjoy Hi-Res Audio to the Fullest: This unit supports playback of Linear PCM 44.1kHz-384kHz/16-32bit and DSD 2.8MHz-11.2MHz. The DAC is equipped with the ES9018K2M, a high-performance audio DAC IC from ESS Technology, renowned for its excellent sound quality. Enjoy high-resolution audio and CDs in premium quality. [Upsampling/Format Conversion Function (SRC)] This unit's built-in SRC (Sampling Rate Converter) allows you to upsample input audio data with the touch of a button, allowing you to enjoy changes in sound. You can also convert input PCM data to DSD data and DSD data to PCM data, respectively, to enjoy changes in sound. (Note: There are some restrictions on the sampling rates and formats that can be selected. For details, see the "SRC Mode Compatibility Table.") If you want to output the input data as is, the unit also features a BYPASS mode, which plays the data directly through without passing it through the SRC. Select your preferred sampling rate and format for each song to enjoy creating the sound you desire. [Can also be used as a preamplifier] The unit comes with one USB, one coaxial, and one optical digital input, allowing connection to a variety of digital devices, including PCs, CD transports, and network audio servers. Easily select between inputs using the selector switch on the front panel. This unit can also be used as a preamplifier-like audio component. Additionally, when connected to a power amplifier with a volume control, the unit's volume is skipped. This is a convenient feature designed for ease of use, as it minimizes circuitry that can degrade sound quality, such as volume adjustment. [Commitment to Headphone Amplifiers] As a headphone manufacturer, we make no compromises when it comes to headphone amplifiers. For this unit, we selected a headphone amplifier IC in line with our development guideline: "To output the highest quality possible without altering the information contained in the sound source." This allows you to enjoy the full potential of the sound source directly and with high quality through headphones. Supports the new USB data transfer method, "Bulk Pet*." USB audio data transfer typically uses the "Isochronous" method. This method processes large amounts of data in a short period of time and transfers intermittently, placing a heavy processing load on the host and device CPUs. High processing loads can also affect sound quality. The "Bulk Pet" method minimizes data transfer and transfers data continuously, evenly averaging the amount of data processed. This revolutionary transfer method reduces fluctuations in the processing load on the host and device CPUs, improving sound quality. The SWD-DA15 supports "Bulk Pet" by installing a driver on your PC. *Bulk Pet is a registered trademark of Interface Corporation. The D/A converter (Digital to Analog Converter) is a crucial component in digital audio, with its quality determining the quality of an audio set. The SWD-DA15 is a remodeled, more affordable version of the SWD-DA20, developed as the core model of the SOUNDWARRIOR desktop audio series. It employs the ES9018K2M DAC IC and is compatible with most currently available high-resolution audio sources (linear PCM 44.1k-384kHz/32bit, DSD 2.8M-11.2MHz). This unit was developed with a focus on the fundamental function of a D/A converter: converting input audio data to analog and outputting it with the highest possible quality. The unit also comes equipped with features that allow users to enjoy a variety of sound changes to suit their preferences. For example, the built-in SRC allows for upsampling of input audio data before playback, and real-time conversion of each format, such as PCM to DSD and DSD to PCM. It also has a function to convert it into a digital signal. It has three digital inputs: USB, coaxial, and optical, and can be connected to a PC, a CD transport, a network audio server, and more. Its compact body fits comfortably on your desktop and is packed with features that allow you to enjoy audio to the fullest.
