K5 Pro Desktop DAC +USB and Headphone Amplifer

The classic lives on with stronger decoding

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, high gain | 768K/32Bit and DSD512 decoding

A concert right at your desktop

With the K5Pro you can truly experience realistic details and a roller-coaster of emotions from your music. The K5 Pro act as a bridge, allowing your computer, speakers and headphones to work together and transport you to a stunning concert hall right from your desktop. 

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 chip with an all-new clock matching management system, with unprecedented capabilities that supports decoding up to a sample rate of 768kHz and hardware native DSD decoding. 

Get truly faithful reproduction of music with coaxial/digital inputs

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. 

Next generation DAC for unrivaled sound quality

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 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.

Specially-designed audio architecture for true high-fidelity sound

When it comes to amplification, the K5PRO is no slouch. The K5PRO 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. 

Utterly precise volume control

The NJRC NW1195A analog volume adjustment chip features an ultra-low output noise of -118dB and is albe 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 K5PRO provides wonderfully smooth, yet high resolution sound. 

Safe, secure and robust external power supply

The K5PRO uses a DA 15V power supply designed to specifically minimize noise. The incoming DC power is filtred 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 a crucial for outstanding sound for such a precisely-designed high performance audio architecture. 

Musical perfection with DAC volume adjustment

Through of the reconstruction of the ADC curve, the K5Pro's volume control allows you to smoothly adjust volume at extremely fine increments without any undesirable noise nor with any channel imbalances. With the K5Pro you can comfortably use various headphones with all kinds of sensitivity. 

Gain control with switches for precise sound 

Both 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 K5Pro 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. 

Finely-textured all-aluminium body

The all.aluminium 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 Oro is a compact, robust unit that doesn't take up much space, perfect for your desk. 

Minimalist yet full of personality

The one-piece all-metal oversized volume knob is seamlessly integrated within the aluminium 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 colors that perfectly complements the minimalism of the rest of the K5 Pro.

  • Blue light: 48kHz and below
  • Yellow light: 48kHz and above
  • Green light: DSD

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

Highly useful beyond imagination, Wide variety of inputs and outputs

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 you phone via USB OTG, or connect your player via coaxial. 

Extremely powerful headphone amplification

The carefully-tuned feedforward amplifier circuit design increases the power output of the TPA120 op-amp by more than 60%, for a total power output of up to 1.5W under a 32Ω load, and up to 20Vpp at 300Ω. The K5Pro easily handles any low or high impedance headphone.

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 2Vmrs, 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  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.

    Cercavo casse ad altissima sensibilita come levecchie klipisch rf3 da collegarci cosa mi consigliate per un i.pianto stereo minimale ma .Porente e abbasfanz ben suonante?

      Buongiorno, il K5 Pro possiede l’amplificatore interno per cuffie ma non un amplificatore per diffusori acustici... occorre abbinare un amplificatore esterno ( o diffusori amplificato) da collegare sulle uscita RCA Line-Out. Gli RCF indicati nell’altra domanda richiedono un ampli di buona potenza data la sensibilità medio bassa, che potrebbe essere il Pioneer A-10 o ancora meglio l’A-30.

        Grazie pensavo di abbinargli il sonic t amp elettrificato? Magari come pre amp all ampli sony che esiste già...potrebbe bastare? ..non dovessi ottenerere risultati deceenti come potenza ci sarebbero diffusori economici alta sensibilità dignitosi da abbinare al solo t amp?

          Il Sonic T-Amp possiede circa 10 watt “veri” e con diffusori dalla media sensibilità può sonorizzare una stanza di piccole dimensioni o comunque essere adatto ad ascolti in campo ravvicinato a volumi non elevatissimi. Per diffusori più efficienti e adatti al T-Amp può dare un’occhiata alle Indiana Line serie DJ.

    Salve, sarei interessato a questo dac/amp della fiio ed avrei alcune domande da farvi. La prima come si comporta con delle cuffie hifiman sundara. La seconda come posso collegarlo al telefono visto che il mio smartphone ha la type c e quale cavo eventualmente utilizzare per la connessione ( se mi postate nello specifico il cavo vi ringrazio) . La terza se è possibile fare acquisti con le agevolazioni della legge 104. Grazie in anticipo!!!

      Buongiorno, grazie alla generosa potenza l’abbinamento in termini di pilotaggio con le HIFIMAN Sundara è buono. Per il collegamento con uno smartphone dotato di connettore usb-c , occorre un cavo adattatore di tipo OTG da usb-c maschio a usb tipo-b maschio. Oppure un adattatore del genere da abbinare ad un normale cavo usb tipo-a/tipo-b già in suo possesso: per acquisti con agevolazioni ex legge 104 preghiamo di contattarci telefonicamente da lunedì.

      Il k5Pro possiede come chip di ingresso USB l’ XMOS XUF208, lo stesso installato sul dispositivo portatile FiiO Q5s, per questo crediamo che non avrà nessun problema a collegarsi via USB agli smartphone Android.

      Buongiorno, il FiiO K5 Pro è appena uscito e la FiiO dichiara che l’alimentazione inclusa è curata. Ciò nonostante è possibile che possa essere migliorabile come spesso accade con molti apparecchi ad Alta Fedeltà. Certamente un cavo speciale USB può essere considerato come upgrade.
