ID6
Triple Timbres, Instantly Switchable
The ID6 offers three selectable timbres: Classic Tube, Modern Tube, and Solid-state. The timbre options apply to the headphone outputs, RCA and XLR line outputs, and preamp outputs.
Its tube stage pairs 12AU7 dual triodes with MOS-FETs delivering two uniquely voiced tube presentations with natural warmth, body, and musicality.
A dedicated tube window puts the glowing filaments on display, enhanced by subtle ambient lighting for a visual experience that complements the sound.
Classic Tube Timbre: Warm, smooth, relaxed, and easy to listen to; vocals are delicate and engaging
Modern Tube Timbre: Expansive soundstage, incisive resolution, and tight, powerful bass.
Solid-state Timbre: Precise and composed, with maximum resolution; ideal for revealing fine detail in classic and instrumental music.
Redefining Fluid Operation
Powered by the Rockchip RK3576 octa-core processor (4x Cortex-A72 @ 2.2GHz + 4x Cortex-A53 @2.0GHz) with a dedicated AI UPU, the ID6 delivers fast, fluid system performance.
Its multi-core architecture handles large music libraries, streaming apps, DSD512 playback, and multitasking with ease - keeping navigation responsive and playback smooth.
Deeply Customised System with Bit-perfect Transmission
Cayin has optimised Android 14 from the low-level drivers to the audio framework for system-wide bit-perfect playback, including through third-party apps. Its USB Audio and I
2S digital paths support up to PCM 32-bit/768kHz and native DSD512.
The HDMI I
2S-LVDS output and USB HOST audio allow the ID6 to serve as a digital source for a compatible external DAC.
Four-channel Discrete Fully Balanced Headphone Amplifier
The ID6 features a four-channel, fully balanced discrete headphone amplifier, with Nexperia audio-grade BJT transistors handling the current gain and output stage.
Switch between Class A and Class AB amplification (DAO) operation to match different listening preferences, while a built-in DC-servo circuit helps maintain a clean, low distortion output.
App Integration
The Cayin Control App puts key ID6 functions at your fingertips, from timbre switching and playback settings on device control.
Dual Mono ES9082Q DAC Architecture
The ID6 employs dual ESS ES9082Q SMART Hi-Fi DACs, each operating in dedicated MONO mode for fully independent left and right channels - improving channel separation, SNR, and overall clarity.
Its channel-summing architecture combines the multi-channel outputs of each DAC to further enhance dynamic range and output performance, preserving fine detail while giving large-scale music greater weight, scale, and authority.
Audiophile-grade USB Processor
The ID6 uses a 16-core XMOS XU316 USB audio processor as its digital interface, with native UAC2.0 and UAC1.0 support for broad compatibility across Windows, macOS, Android, Linux, and other major platforms.
Its asynchronous transfer architecture and precision clocking help reduce jitter and the effect of source-side noise, supporting stable high-resolution playback.
Play Freely, Store Flexibly
Dual-band 2.4GHz/5GHz Wi-Fi supports online streaming and major casting protocols for flexible network playback
Qualcomm QCC5125 Bluetooth delivers stable wireless performance with support for multiple high-resolution audio codecs
A dedicated M.2 NVMe 2280 SSD slot supports high-capacity local storage for large music libraries
Music can also be played from internal storage, USB drives, external hard drives, and card readers
Independent Digital & Analog Power Supplies
The ID6 is built around a high-performance toroidal transformer, with fully independent power supplies for the digital and analog sections.
High-efficiency DC-DC regulation, ultra-low-noise linear regulators, and polymer molybdenum filter capacitors work together to supress ripple and circuit noise - providing clean, stable power for the entire audio path.
All in One
The ID6 combines a streamer, DAC, preamplifier, and headphone amplifier. Digital inputs accept compatible sources such as CD players, while its line and preamp outputs connect to amplifiers. Digital outputs can feed an external DAC.
Thoughtful Details
A 6-inch 1080 x 2160 FHD+ display features a custom landscape UI with multi-touch control, while the seamless black glass panel creates a cleaner, more refined front profile.
A dedicated ADC feedback circuit works with the SoC to analyse audio in real time, enabling dynamic spectrum visualisation and VU meter display.
The precision-tuned volume knob offers smooth, controlled resistance, with an integrated illuminated ring that also indicates the current audio format.
Dual-side ventilation improves heat and dissipation for stable operation.
External high-gain antennas were included to strengthen both Wi-Fi and Bluetooth connectivity.
Compact, Premium
The chassis is machined from a single piece of aluminium alloy, then finely sandblasted and anodised for a smooth, premium finish.
