FiiO K5 Pro Headphone Amps with 768K/32Bit and Native DSD512

AKM AK4493EQ DAC chips in the K5 Pro provide a smooth, pleasant, and detailed sound. The device supports audio up to 768kHz/32 bit sampling rates and features native DSD XMOS USB Audio.

The K5 Pro utilizes the XMOS XUF208 microcontroller for its stability, powerful functionality, and proven reliability. It also features the NJRC NW1195A analog volume adjustment chip paired with flagship TI TPA6120 op-amp and OPA1642 JEFT op-amp for precise volume control.

The device employs ADC volume control to eliminate channel volume imbalances and allow the user to smoothly adjust the volume to a more accurate and finer degree. The all-aluminum black body has been CNC-machined, anodized, and sandblasted for a robust yet perfectly textured feel.

Gain switches allow for switching between low, medium, and high gain levels, while the unique RGB status lights indicate the current sample rate.

Toggle switches make it easy to control input selection and gain, and the device offers versatility with multiple interfaces including Coaxial, Optical, and RCA line-in.

The K5 Pro also features powerful headphone amplification, generating up to 1.5W power output under a 32Ω load and up to 20Vpp at 300Ω. It is accompanied by a safe, secure, and robust external power supply designed to minimize noise and power supply ripple.

The K5Pro ESS headphone amplifiers feature a high level of resolution sound and supports various inputs including coaxial, optical, and RCA line-in inputs. It supports 6.35mm (1/4 in.) headphone out/RCA line-out outputs and can easily handle low or high impedance headphones.

With ADC volume adjustment, the K5Pro ESS portable headphone amplifier allows for smooth volume adjustments at extremely fine increments, accommodating various headphones with all kinds of sensitivities.
