FIIO PRESENTS THE ALL-NEW DESKTOP DAC AND AMPLIFIER - THE K5 PRO ESS
FiiO introduces the latest K5 Pro ESS desktop DAC and Amplifier. Building on the
K5, a pure desktop amplifier, the team added DAC functionality coupled with the high performance of K5 to
create the new K5 Pro ESS Desktop DAC and Amplifier. The K5 Pro ESS connects to an audio player via a
digital audio interface and works with a computer as a professional desktop decoding amplifier. Adopting
Sabre's high-performance audio DAC chip, ES9038Q2M with 32-bit processing, to achieve a new height of
decoding audio. The audio architecture is further elevated with an XMOS USB decoding chip with an all-new
clock matching management system, with unprecedented capabilities that support decoding up to a sample rate
of 768kHz PCM and native DSD decoding.
EMBEDDED WITH ESS SABRE + XMOS CHIPS FOR PRISTINE PLAYBACK AND DECODING
The new FiiO K5 Pro ESS has been upgraded to keep up with the times to offer high-fidelity audio. The K5 Pro ESS employs the flagship portable ESS DAC chip, the ES9038Q2M, with outstanding performance and richer audio details. Compared to the last generation K5, the distortion has reduced by 50%, the crosstalk has increased by 6dB with greater channel separation, and the dynamic range has increased by 3dB. The K5 Pro ESS also features a high-performance XMOS XUF208 USB decoding chip equipped with a clock matching management system, allowing decoding up to a sample rate of 768kHz/32bit and DSD512 natively. This capability enables the K5 Pro ESS to decode and play your music at the highest quality.
POWERFUL HEADPHONE AMPLIFICATION WITH 3 GAIN LEVELS FOR VOLUME CONTROL
The upgraded FiiO K5 Pro ESS now offers amplification functionality. The K5 Pro ESS features a carefully-tuned feedforward amplifier circuit design that increases the power output of the TPA6120 OP-Amp by more than 60%. This offers a total power output of up to 1.5W under a 32ohm load, and up to 20Vpp at 300Ohms. To add to this, you also get 3 gain level settings - Low, medium, and high gain, allowing you to use the K5 Pro ESS with almost any headphone at comfortable volume levels. Through the reconstruction of the ADC curve, the K5 Pro ESS's volume control allows you to smoothly adjust the volume at extremely fine increments without any undesirable noise or with any channel imbalances. With the K5 Pro ESS, you can comfortably use various headphones with all kinds of sensitivities.
EXPERTLY DESIGNED AUDIO ARCHITECTURE FOR HIGH-FIDELITY AUDIO PLAYBACK
FiiO K5 Pro ESS does not fall behind when it comes to amplification power. The K5 Pro ESS has generous space to embed and package the necessary components for exceptional analogue amplification. It packs a four-level audio circuit capable of providing extraordinary audio fidelity in its class with Second-order LPF + Analogue 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. This entire audio architecture has been specifically designed to extract the optimum performance of the K5 Pro ESS.
OFFERS A VARIETY OF INPUT AND OUTPUT CONNECTIVITY OPTIONS FOR EASY USE
No matter what audio equipment you use, digital audio has advantages in the integrity and fidelity of audio signals transmitted. The team of acoustic engineers at FiiO understood this and granted the K5 Pro ESS capabilities to allow you to take advantage of digital audio with optical and coaxial inputs supporting up to 96kHz inputs. This connectivity is convenient for connecting various music players and digital interfaces. Besides the wide variety of digital inputs options, the K5 Pro ESS also features a traditional analogue RCA line-in. RCA line-in is not only more robust and less prone to breakage than 3.5mm line-in, but it also has better resolution. The RCA line-out line signal is adjustable up to a maximum of 2Vrms, allowing the K5 Pro ESS to be used with a variety of active speakers and external amplifiers.
SHOWCASING A MINIMALISTIC DESIGN WITH A SECURE AND ROBUST POWER SUPPLY
FiiO K5 Pro ESS is designed with quality materials featuring a one-piece all-metal oversized volume knob that is seamlessly integrated within the aluminium front panel, allowing you to easily and comfortably control volume. The RGB light indicator lights up with different colours according to the sample rate of the played audio. The input selection and gain are controlled by tactile toggle switches, which are clearly labelled, allowing you to control your music. The K5 Pro ESS utilises a DC 15V power supply engineered to minimise 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 components. This design effectively suppresses power supply ripple and minimises power supply crosstalk between the two major sections of the circuit. This allows for more stable and less noisy power.

For the price there is very little to complain. I have given four stars, why not five? In terms of absolute sound quality it does not get five but does get a very good four.
It is nothing short of amazing what DACs can do today for this little money, a decade back you could not imagine the refinement in DACs at this price point. If you are starting out or perhaps a little lost in your path dabbling with Headphones in the region of 10 to 15K, look no further than this. It will suffice and some more.
Serious audiophiles, if you are one you probably are looking at products of a different league. I do not mean more expensive products, yes, you do kind of get what you pay for but if you can not afford the true top end offerings then there is always the DIY community to help you out.
I will not get into too much detail on the sound, at this price-point they generally sound decent. I have admired Fiio over the years for what they offer for the money, this is no different. Sound is dynamic, not clinical but neutral. The 'digital glare' that audiophiles talk of, you will find it here but definitely not to the extent of ruining your music. As I have mentioned earlier, you are not going to feel you are missing something as long as you pair this with similarly priced headphones. Go higher though and then the itch starts. It struggles to drive my Hifiman Edition XS to its full potential, you know it when you play complex compositions with expansive sound stage and ambience. For example Hans Zimmer or John Williams. You come away with the distinct impression that there is more to be had, that bassoon could sound more tuneful or that cello could tear into you a bit more. No I do not dream of these things, I have enough experience to know when it is missing.
So in conclusion, amazing device for the money, very little to complain. Beautiful sound for the money. Seasoned audiophiles, you will want more.
We really appreciate the genuine feedback, we'll share your thoughts with the brand as well!
This desktop DAC AMP is hard to beat for the price given the specifications and features. Works magically with my DT770 Pro 250ohm headphones and FH3 IEM. The Fiio K5 pro is a fantastic entry level desktop DAC+AMP.
Thanks for the great review & we hope you had comfortable shopping experience. We are sure your review is gonna help other beginner audiophiles to make an informed decision. Cheers & Welcome to the world of audiophilia!
