Flagship ES9038Q2M Chip & XMOS Decoding Chip

The K5 Pro ESS employs the flagship portable ESS DAC, the ES9038Q2M with more outstanding performance and richer audio details. Compared to the last gen, the distortion has reduced by 50%, the crosstalk for LO has increased by 6dB with greater channel separation, and the dynamic range has increased by 3dB. The XMOS XUF208 USB decoding chip equipped with the clock matching management system, allows decoding up to a sample rate of 768kHz and native DSD512.

Specially-Designed Audio Architecture

When it comes to amplification, the K5 Pro ESS is no slouch. The K5 Pro ESS has generous space to fit and package the necessary components for exceptional analog amplification,and packs a four-level audio circuit capable of providing extraordinary audio fidelity in its class: second order LPF + analog volume adjustment + voltage amplification + current drive. Each part of the amplification circuit works perfectly together in harmony for excellent dynamic range and high resolution of sound.

Accurate Volume Adjustment

Through reconstruction of the ADC curve, the K5 Pro ESS' s volume control allows you to smoothly adjust volume at extremely fine increments without any undesirable noise nor with any channel imbalances. With the K5 Pro ESS, you can comfortably use various headphones with all kinds of sensitivities.

3 Gain Levels

Both the input selection and gain are controlled by tactile toggle switches, which are clearly labelled allowing you to easily control your music. Low, medium, and high gain levels are available allowing you to use the K5 Pro ESS with almost any headphone at comfortable volume levels. A purely hardware gain circuit is used at low gain, with unaffected and uncompromised dynamic range and overall music fidelity.

1.5W Large Power

The carefully-tuned feedforward amplifier circuit design increases the power output of the TPA6120 op-amp by more than 60%, for a total power output of up to 1.5 W under a 32Ω load, and up to 20Vpp at 300Ω. The K5 Pro ESS easily handles any low or high impedance headphone.

Support Coaxial/Optical/RCA Line Inputs & RCA Line Out

No matter what audio equipment you use, digital audio inherently has advantages in integrity and fidelity of signals transmitted. The K5 Pro allows you to take advantage of digital audio with optical and coaxial inputs supporting up to 96kHz inputs, convenient for connecting various music players and digital interfaces. Besides the wide variety of digital inputs, the K5 Pro also features a traditional analog RCA line-in. RCA line-in is not only more robust and less prone to breakage than 3.5mm line-in, it also has better resolution. The RCA line-out line signal is adjustable up to a maximum of 2Vrms, so the K5 Pro ESS can be used with a variety of active speakers and external amplifiers.
*When using the line out, please disconnect your headphones

Disappointed

Ordered the Dac/Amp and waited for 2 weeks for the product. Chose a US plug and the package came with a Type I plug, so disappointed. Now I have a product that I can't use without ordering another cable.
