D1, a fusion of a DAC and a pre-amp with style, is conceived and designed not only to make music based on digital data real and pleasurable, but also to meet the demand of those with willing and perfectionist ears. It renders crystal clear, spacious and dynamic music.

The exterior of D1, composed of aerospace grade aluminum alloy which seals off electric and magnetic interference from outside, is crafted finely to embody a structure of straight lines and a single circle.

COS’s proprietary algorithm with a linear-phase delay FIR filter can up-sample original data to 176.4K or 192K, and this massive computation is handled by a powerful 3648 MMAC/sec DSP.

D1 stores digital data in a one-second buffer before converting to analog signals, under the coordination of a crystal oscillator with a jitter precision less than 1ps and a dedicated re-clocking circuitry.

Two torroid transformers power the digital circuit and the analog circuit separately, thereby eliminating possible interferences.

The analog circuit bifurcates into two boards to eliminate cross-talk, and the high-performance DAC chips, one on each board running as mono, are manually tuned and matched to attain a lower distortion.

D1’s balanced design ensures that even harmonics match and are gracefully cancelled out. Distortions are low to the extent possible.

D1’s volume control is composed of a ladder of high precision resistors and an array of analog switches which are low in resistance, noise, and distortion.

Awards & Reviews
6moons.com’s Blue Moon Award.

Audio Art’s Best Value Award 2016. (in Chinese)

6moons.com: “An advanced, very stylish DAC/Preamp.”

Audio Art: “…lively sound, scintilating and sweet….” (content in Chinese)

HiFi Knight: “This device offers fluency and coherence on a level very rarely heard. Extremely black background and instruments separation are both cherries on top….”

Inearspace Good Buy Award, “Beauty In and Out.”

HiFi+: “…full of expression and nuance….”

HiFi Pig: “It is rare for a first product to be so good. For £8000 (€9000) it might not be cheap, but it is that good.”

Doug Schroeder: “Unforgetable sound.”
