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.

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.

Not much to complain

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!

For every Audiophile beginner

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.

Great DAC/Amp at this price point

I was a bit sceptical if this would drive my HD600 and was pleasantly surprised by the details it got out. I was using a portable DAC/Amp earlier and this really justified the greatness of HD600. Created super wide soundstage for me, especially in Atmos coded content.

Hey Vikas, thanks a lot for this lovely review and we are glad you are enjoying it! Keep the music playing.
