Cayin ID6 High-Resolution Streamer, DAC, Valve Headphone Amplifier & Preamplifier
Frequently Bought Together
Product Overview & Specifications
The Cayin ID6 is a reference high-resolution network streamer, dual-mono DAC, digital preamplifier, and fully discrete headphone amplifier anchored by hand-matched 12AU7 vacuum valves. Built upon a customized Android 14 operating system with a Rockchip RK3576 processor, the ID6 features a system-wide bit-perfect audio architecture that bypasses standard Android sample-rate conversion. Its dual ESS ES9082Q DACs operate in MONO configuration alongside an XMOS XU316 USB interface, processing audio formats up to PCM 32-bit/768kHz and native DSD512.
What sets the ID6 apart is its versatile analogue output stage. Listeners can choose between three distinct timbres: Classic Tube, Modern Tube, and neutral Solid-State. Crucially, the 12AU7 tube stage applies across all analogue outputs—including the headphone jacks, fixed RCA/XLR Line Outputs, and variable RCA/XLR Pre Outputs—allowing you to feed tube warmth into external amplifiers, power amps, or active speakers. With a 6-inch Full HD+ touchscreen, internal M.2 NVMe SSD expansion (up to 2TB), and comprehensive streaming app support (Qobuz, TIDAL, Apple Music, Spotify), the ID6 serves as a total digital-and-analogue hub.
KEY FEATURES & SYSTEM HIGHLIGHTS
- Selectable Tri-Timbre Analogue Output: Choose between Classic Tube (warm and organic), Modern Tube (fast and open), or Solid-State (neutral and precise) sound signatures.
- System-Wide Valve Processing: 12AU7 tube processing is routed through all rear RCA/XLR Line and Pre Outputs as well as the headphone outputs.
- Dual ESS ES9082Q MONO DAC Architecture: Dedicated left and right channel DAC implementation for superior channel separation, wide dynamic range, and low distortion.
- Four-Channel Fully Discrete Headphone Amp: Balanced, four-channel discrete headphone circuit with selectable Class A and Class AB bias modes, delivering up to 4.0W + 4.0W into 16 Ω.
- Bit-Perfect Android 14 Engine: Bypasses Android's native sample rate conversion (SRC) across all integrated streaming applications, including Qobuz, TIDAL, Apple Music, Amazon Music, and Deezer.
- Comprehensive Digital & Network I/O: Features HDMI ARC, I²S-LVDS, Coaxial, Optical, USB DAC input/output, Gigabit Ethernet, Dual-Band Wi-Fi, AirPlay 2, and Bluetooth wireless connectivity.
- M.2 NVMe SSD Expansion: Internal 2280 NVMe SSD slot supports up to 2TB of high-speed local digital storage for high-resolution audio libraries.
- 6-Inch FHD+ Touchscreen & App Control: High-definition touchscreen display with dynamic VU-meter/spectrum graphics, supported remotely by the Cayin Control App.
