C O S　D 1 0
D10 is a dream component for your beloved sonic pleasure. It is a DAC, a pre-amp, and a headphone amp, well built with streaming capability. Yes, the same spacious, supple and dynamically powerful sound that COS products have been offering. D10 is also a phono amp, one that delivers from your preferred vinyls luscious vibes.

Retail prices in the MY including TAX :
D10 without modules: RM22,000
Streaming module: RM4320
MM/MC Phono preamp module: RM4320

COS ALGORITHM, BUFFER and RE-CLOCKING
COS's proprietary algorithm with a linear-phase delay FIR filter can up-sample original data to 176.4K or 192K. D10 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.
 
STREAMING (optional)
Stable and quality streaming is available, with or without a wire, for TiDAL, Spotify, Deezer, and Qobuz. Setup is easy with iOS and Android applications.
 
PHONO-AMPLIFIER (optional)
There are 5 loading resistors and 3 loading capacitors, all selectable, to accommodate phono cartridges of your choice. Other features include JFET input stage, on-board low-noise linear regulator, and handpicked components for RIAA curve matching and zero capacitor between audio signal paths. Extremely low in noise and distortion.
 
TWO-LAYER HOUSING
D10 has an NCT internal chassis and an aluminum exterior. This design provides a fortified frame that make possible lowered noise and minimized interference, plus a fine outlook.
