Quad-DAC Mode for True Hi-Fi Sound
For the first time in the A&norma series, the SR35 deploys the CS43198 DAC from Cirrus Logic, in Quad DAC configuration. A very well-received DAC praised for its outstanding spatial sense and resolution.
In addition to this, a new design of audio circuit has been implemented, incorporating Astell&Kern's unique technologies along with the Quad DAC and our patented TERATON ALPHA technology for outstanding advancement in the dynamics, sense of space, resolution, and the level of separation. Furthermore, our latest technologically advanced amplification circuitry, which was only available in our flagship products has now been incorporated into the SR35, boasting a dramatically improved and industry-leading SRN of 130dB.
A Dual/Quad DAC Switching mode is offered to enable users to adjust and improve power management efficiency, further improving the long continuous playtime, a core feature of the A&norma series.
