Unit powers on and appears to operate normally through RCA and optical, but is not functional as a USB dac and is not registered or recognized by connected PCs. No cracks, chips, damage, or identifiable defects to explain this issue. Will be packaged and shipped carefully same or next day by an experienced seller.

This is the AKM version, not the ESS version. This version is rarer and is generally the more preferred version between the two. Some slight cosmetic imperfections, but perfect in functionality. High-performance DAC: AK4493 | USB decoding chip?XMOS XUF208 coaxial/optical/RCA line-in | 6.35mm (1/4 in.) headphone out/RCA line-out low, medium, and high gain | 768K/32Bit and DSD512 decoding The classic lives on with stronger decoding Desktop DAC and Amplifier Specially-designed audio architectureor true high-fidelity sound When it comes to amplification, the K5 Pro is no slouch. The K5 Pro has generous space to fit and package the necessary components for exceptionalanalog 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. The NJRC NW1195A analog volume adjustment chip features an ultra-low output noise of -118dB and is able to adjust volume by 0.5dB per step. And when this is paired with the combination of the flagship TI TPA6120 op-amp and the OPA1642 JFET op-amp,the K5 Pro provides wonderfully smooth, yet high resolution sound. Utterly precise volume control 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 192kHz inputs, convenient for connecting various music players and digital interfaces. Get truly faithful reproduction of music with coaxial/digital inputs Naturally gifted at decoding In the K5 Pro, clock management is improved and overall decoding performance is excellent. This is due to the XMOS XUF208 USB decoding chipwith an all-new clock matching management system, with unprecedent capabilities that supports decoding up to a sample rate of 768kHz and hardware native DSD decoding. Safe, secure, and robust external power supply The K5 Pro uses a DC 15V power supply designed to specifically minimize noise. The incoming DC power is filtered with a secondary power supply, which then independently supplies power to the amplification part of the audio circuit and the rest of the circuit. This effectively suppresses power supply ripple and minimizes power supply crosstalk between the two major sections of the circuit, for a more stable and less noisy power that is crucial for outstanding sound for such a precisely-designed high performance audio architecture. 1. Desktop DAC and amplifier like a USB sound card + full-sized headphones 2. DAC for external sources like a USB sound card +active speakers 3. Powerful amplifier for mobile devices Connect your phone via USB OTG?or connect your player via coaxial Highly useful beyond imagination? Wide variety of inputs and outputs The one-piece all-metal oversized volume knob is seamlessly integrated within the aluminum front panel, allowing you to easily and comfortably control volume. The RGB light indicator that surrounds the volume knob lights up with different colors according to the current sample rate, giving a lively splash of color that perfectly complements the minimalism of the rest of the K5 Pro. Minimalist yet full of personality 48kHz and below ——Blue light 48kHz and above ——Yellow light DSD——Green light Getting precise with toggle switches Both the input selection and gain are controlled by tactile toggle switches, which are clearly labelled allowing you to easily control your music. 3 gain levels? Low 0dB Medium+6dB High +10dB 3 input modes USB DAC SPDIF IN LINE-IN Finely-textured all-aluminum body The all-aluminum body is repeatedly polished with CNC and is then carefully finished with anodizing and fine sandblasting, for a smooth yet finely-textured shell. The K5 Pro is a compact, robust unit that doesn’t take up much space, perfect for your desk. 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 32? load, and up to 20Vpp at 300?. The K5 Pro easily handles any low or high impedance headphone. Extremely powerful headphone amplification The K5 Pro achieves new heights in sound quality, thanks to the high-performance AKM AK4493 DAC with 32-bit processing and VELVET SOUND technology, along with the XMOS USB decoding chip with 768kHz and DSD inputs. With the left and right audio channels being independently handled and fully differential audio output, the K5 Pro has such a high level of resolution you will be hearing details you never noticed before. Next-generation DAC for unrivalled sound quality Through reconstruction of the ADC curve, the K5 Pro’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, you can comfortably use various headphones with all kinds of sensitivities. Musical perfection with ADC volume adjustment Gain control with toggle switches for precise sound 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 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. RCA line-out for high quality output to other sources 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 can be used with a variety of active speakers and external amplifiers. *When using the line out, please disconnect your headphones The companion for your player K5 Pro could support Coaxial/Optical/Line in. Using FiiO’s customized Type C to USB B cable to connect with DK1 (Type C version), K5 Pro could work as a “dock” for your player to achieve lossless decoding and drive big headphones. Since K5 Pro is powered by DC adaptor, it wouldn’t consume power from the USB port. https://www.fiio.com/k5pro

The FiiO K5 Pro is a portable desktop audio amplifier with digital features. It has 2 channels and 4 inputs, and comes in black color. The model supports up to 768K/32Bit and has RCA, headphone jack, and digital optical TOSLINK audio outputs. It is designed for use with headphones and is suitable for home audio setups.

I am selling my lightly used K5 Pro headphone DAC/Amp. It was used for casual gaming and music listening, but I have gone back to a wireless headset on my PC. Unfortunately I do not think I will be using this anymore since I am no longer used wired headphones. Includes original box, cables, and papers. No damage. Comes from a smoke and pet-free home.

FiiO K5 Pro Kopfhörerverstärker / USB DAC / Netzteil / OVP(seltenst genutzt)Der Desktop-Verstärker FiiO K5PRO verfolgt den gleichen Gedanken wie sein Vorgänger: Am Schreibtisch exzellenten Klang zu liefern. Die Evolution ist allerdings, dass er nun einen eigenen, hochwertigen Digital-/Analog-Wandler mitbringt.Weitere Infos im www.
