DAC ZWEIMANN USB
commitment to Hi-Res audio playback and supports
gapless playback and the ability to play DSD, Quad DSD and PCM along
with other Hi-Res formats. The
DAC ZWEIMANN USB
has what it takes to
help you enjoy your music, and to discover how truly amazing music can
sound on a DAC engineered for hi-res analog and digital audio.
As befits a device that will be the heart of a digital audio system, the
DAC
ZWEIMANN USB
employs VERITA AK4490 DACs, designed by Asahi Kasei
Microdevices Corporation for use in high-end audio equipment.* 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
DAC ZWEIMANN USB
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 pre-amp section, the
DAC ZWEIMANN USB
employs a fully-balanced
circuit design from the output of the D/A Converters and Volume Amplifier
section. Control signals from the volume knob precisely control four
independent variable-gain amplifiers simultaneously — 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
