Award winning all-in-one DAC, Preamp, Headphone and Phono Amp
For 2022 COS Engineering updates its award-winning digital source to version 2. A transformer upgrade has lowered the heat, removing the need for a ventilating logo from the top panel.
D10 is Roon Ready & Roon Tested device, also MQA enabled for audio file and stream playback, delivering the sound of the original master recording.
6moons 2020 Award Winner:
‘Highly accomplished 5-in-1 D/A converter’
“The COS Engineering D10 from Taiwan is a modern multi talent whose modular concept allows each buyer to bundle the features they want. With the slide-in modules, this can easily be post purchase, no dealer visit or two-way shipping involved.
lt’s been strange times but 2020 hindsight calls the D10 one highlight of this year!”

COS D10 MARK 2
DAC – Pre-Amp – Headphone Amp
DESCRIPTION
Mark 2.
A transformer upgrade has lowered heat, removing the need for a ventilating logo from the top panel.
D10 is Roon Ready & Roon Tested device, also MQA enabled for audio file and stream play back, delivering the sound of the original master recording.
D10 is a ‘dream gear’ 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.
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.
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.
COS D10
Phono Stage Module
DESCRIPTION
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.
COS H1
DAC – Headphone Amplifier
DESCRIPTION
H1 is an audiophile-grade DAC plus headphone amplifier, featuring COS Engineer’s proprietary digital-to-analogue algorithm. For those who seek acoustic joy through headphones, H1 is a ‘must have’ because of the details and the smooth yet dynamically powerful sound it provides.
COS ALGORITHM AND DSP
COS’s proprietary algorithm with a linear-phase delay FIR can up-sample original data to 176.4K or 192K, and this massive computation is handled by a powerful 3648 MMAC/second DSP.
BUFFER AND RE-CLOCKING
H1 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.
HEADPHONE
4 power amplifiers to accommodate 2 unbalanced headphones or 1 balanced headphone.
POWER
H1 harnesses a selected switching mode power supply with specially designed circuitry for lower noise, and galvanic isolation between digital and analog circuitries are added to prevent audio signals from being contaminated.
VOLUME Control
H1’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.
COS D10
Streaming Module
DESCRIPTION
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.
