Refined Dual Mono D/A Converters Derived From Top-of-the-Line Components

The D/A converters analog output circuitry features both excellent high-end resolution and natural musical texturing that only high-end components such as Esoterics K Series SACD players can offer. Centered around Asahi Kaseis high-end AK4490* 32-bit DAC, this circuitry accentuates the expressive power of these players with 4 parallel/differential circuits and 8 outputs driving each channel—twice that of conventional players in terms of circuit scale—to further enhance sound quality with excellent linearity and low distortion.
Arranged in a discreet dual mono configuration, the D/A converters and analog output circuitry are laid out in parallel on either side of the board, and are completely isolated from the digital signal processing circuitry, achieving superb channel separation.

USB Support for 2.8/5.6/11.2MHz DSD, 384kHz/32-bit PCM and Asynchronous Transmission

In addition to playback at the original sampling frequency, 2X, 4X and 8X up-conversion of the PCM digital signal is also provided. A range of D/D conversion modes are also available for the PCM format, such as PCM-to-DSD conversion.
*AK4490 is a branded product of Audio4pro™ and of Asahi Kasei Microdevices Corporation, and designed for professional studio and digital audio applications.
