HIFI ESS9038 USB DAC Digital to Analog Converter Desk Headphone Amplifier DSD256 Item description Features Douk Audio K5 USB DAC & Headphone Amp: Featuring USB and SPDIF optical inputs, as well as optical, RCA and 6.35/3.5mm jack outputs, the K5 serves as a high-performance headphone amplifier, a USB DAC, a preamp, but also a USB to optical converter to transmit the high-quality audio from the computer to those audio devices only with SPDIF digital input such as CD players, amplifiers and active speakers etc. High-end Chipset and Top-level Parameters: The K5 adopts ESS9038Q2M (DAC), SA9312 (DSP), OPA1678 (LPF) and SGM8262 (amp) op-amps, and supports PCM 32bit/384kHz high-resolution decoding and DSD256 playback. Its excellent circuit design ensures superior performance with a SNR over 121dB, a low noise floor of only 3μV and an incredibly low THD of 0.0007%, K5 delivers an exceptional listening pleasure with its ultra-pure sound. Strong Power and High/Low Gain Modes: K5 supports dual 6.35/3.5mm headphone outputs and provides robust power of 560mW/470mW@32Ω per channel to effortlessly unleash the best performance of your headphones. Specially designed with high and low gain modes, flexibly adapt to all headphones of a wide impedance range from 16Ω to 600Ω and tailor your own listening experience. Tone Control with Bypass and Gain Switch: Treble and bass with midpoint positioning for perfect balance, the K5 also features a bypass function to remove all tone controls, allowing you to enjoy the purest sound by toggling the switch to PURE. The USB Type-C input can power the K5 directly with sufficient current, it also has an external power port and includes a 2-in-1 USB cable (Type-C and USB-A) for broader compatibility and optimal performance. User-Friendly Design for Easy Operation: Besides input, tone and gain one-click switch , the K5 also integrated the volume and power button into one to simplify the use; with colorful LED indicators, clearly show the current working mode and sampling rate; aluminum alloy body and CNC-molded, compact but durable and reliable, very suitable for those who pursue HIFI sound. Warm Tips: 1. The K5 USB DAC is not compatible with Win7 system. 2. The USB input (type-C) can transmit audio signals and provide power to the K5. If the current is above 2A, there is no need to use the external DC power interface. If less than 2A, please use the supplied high-quality DC5V/2A power adapter to ensure the performance of the K5. 3. The volume and tone knobs only control the analog audio outputs (RCA/6.35 / 3.5mm jacks), invalid for the optical output. 4. The optical output is only valid when using the USB input. While the analog outputs of RCA, 6.35 and 3.5mm jacks will work no matter using the USB or Optical input. 5. For DSD playback, no USB driver is required if the computer is running MAC OS, linux or Android systems. While for Windows 10/11 system (Not support Win7), please contact us for the USB driver or download directty from the user manual.
