Douk Audio K5 PC DAC Headphone Amplifier with USB & Optical Input DSD256 for Amplifier, Speaker, Mac, Computer

Description

Brand: Douk Audio

Characteristics:

  • Douk Audio K5 USB DAC & Headphone Amplifier: Featuring optical USB and SPDIF inputs, as well as optical, RCA, and 6.35/3.5 mm jack outputs, the K5 serves as a high-performance headphone amplifier, USB DAC, and preamplifier, as well as a USB-to-optical converter for transmitting high-quality audio from your computer to audio devices with SPDIF digital inputs, such as CD players, amplifiers, and powered speakers.
  • High-end chipset and top-level parameters: The K5 uses ESS9038Q2M (DAC), SA9312 (DSP), OPA1678 (LPF), and SGM8262 (Amp) operational amplifiers, supporting high-resolution PCM 32-bit/384kHz decoding and DSD256 playback. Its excellent circuit design ensures superior performance with an SNR of over 121dB, a low noise floor of only 3μV, and an incredibly low THD of 0.0007%. The K5 offers exceptional listening pleasure with its ultra-pure sound.
  • Powerful Performance and High/Low Gain Modes: The K5 supports two 6.35/3.5mm headphone outputs and delivers a robust output of 560mW/470mW@32Ω per channel, effortlessly delivering the best performance from your headphones. Specially designed with high and low gain modes, it flexibly adapts to any headphone with a wide impedance range from 16Ω to 600Ω, allowing you to customize your listening experience.
  • Tone Control with Bypass and Gain Switch: Treble and bass are centered for perfect balance. The K5 also features a bypass function that removes all tone controls, allowing you to enjoy the purest sound by switching the switch to PURE. The USB Type-C input can directly supply the K5 with sufficient power. It also features an external power port and includes a 2-in-1 USB cable (Type-C and USB-A) for wider compatibility and optimal performance.
  • User-friendly design for easy operation: In addition to one-click input, tone, and gain controls, the K5 also integrates volume and power buttons for convenient use. Colorful LED indicators clearly display the current working mode and sampling rate. The aluminum alloy body and CNC-formed design are compact yet durable and reliable, making them ideal for those pursuing HiFi sound.
  • Warm Tips: 1. The K5 USB DAC is not compatible with Win7 systems. 2. The USB (Type-C) input can transmit audio signals and supply power to the K5. If the current is above 2A, it is not necessary to use the external DC power interface. If less than 2A, please use the included high-quality DC5V/2A power adapter to ensure the performance of the K5. 3. The volume and tone controls only control the analog audio outputs (RCA/6.35/3.5mm jacks); the optical output is invalid.
  • 4. The optical output is only valid when using the USB input. The analog outputs (RCA, 6.35mm, and 3.5mm) work regardless of the USB or optical input. 5. DSD playback does not require a USB driver if the computer is running MAC OS, Linux, or Android systems. For Windows 10/11 systems (Win7 is not supported), please contact us for the USB driver or download it directly from the user manual.
