COS Engineering’s proprietary algorithm up-samples original data to 176.4K or 192K, 24-bit by a process in an array of 4096 with 32-bit precision. To rule out phase contamination that may stem from the more computationally efficient IIR filter, a linear-phase delay FIR filter is chosen. This massive computation is handled by a powerful DSP capable of 3648 MMAC (millions multiply and add) per second.
BUFFER AND RE-CLOCKING

D2 receives data from digital sources, whether a PC, a CD transport, or a mobile device, aligns them in exact frames with a one-second buffer, and sends them out for interpretation by the COS algorithm. The data so processed is then converted to analog signals, under the coordination of a crystal oscillator with a jitter precision less than 1ps and a dedicated re-clocking circuitry.
POWER

D2 harnesses two selected switching mode power supplies with specially designed circuitry for lower noise. These power supplies work with 100~240VAC; there is no need to select voltage.
FULL BALANCED DESIGN

Balanced designs are applied throughout the entire audio signal path. Even-order harmonics on the differential signal pairs are carefully matched and are thus gracefully cancelled in order to achieve the lowest possible distortions.
GALVANIC ISOLATION

The galvanic isolation between digital and analog circuitries further ensures that the audio signal is not to be contaminated.
VOLUME CONTROL (D2V ONLY)

D2’s volume control is composed of a ladder of +-0.1% high precision resistors and an array of analog switches which are low in resistance, noise, and distortion. No mechanical parts are used. Frequent use does not erode its precision.
