K5 PC DAC Headphone Amplifier Digital to Analog Converter with USB & Optical Input DSD256 for Amplifiers, Speakers, Mac, Computer (K5)
- 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 3V 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@32 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 16 to 600 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 direc
