As befits a device that will be the heart of a digital audio system, the ZWEIMANN DAC employs two VERITA AK4490 DACs, designed by Asahi Kasei Microdevices Corporation for use in high-end audio equipment.
The VERITA AK 4490 chips are widely use in audio equipments:
The VELVET SOUND architecture of the AK4490 is capable of producing a finely-detailed and expressive sound at frequencies audibility, necessary for Hi-Res Audio playback. And newly developed Low Distortion Technology achieves 112dB of S/(N+D) which is the highest level in the industry for a 120dB-class DAC.
As well as 11.2MHz DSD Native playback, the ZWEIMANN DAC also supports wide variety of Hi-Res Audio sources, including 384kHz/32-bit PCM, and delivers on Hi-Res Audio’s promise of smooth, ultra-detailed sound and an outstanding soundstage.
In the tube section, the ZWEIMANN DAC employs a fully-balanced circuit design from the output of the D/A Converters with four amplifiers — both positive and negative for the left and right channels. With this circuit design, audio signal paths are simplified and independent left and right channels and phase is preserved for clear sound quality with outstanding channel separation.
“..ZWEIMANN DAC is first and foremost an example of excellent dynamics and micro dynamics as well as a thorough separation of noises on a clear noise free background..”
