It means K5 Pro ESS amplifier can drive most of the headphones selling in the market. 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 amps with almost any headphone at comfortable volume levels. A pure hardware gain circuit is used at low gain, with unaffected and uncompromised dynamic range and overall music fidelity. Accurate volume adjustment Through reconstruction of the ADC curve, the desktop headphone amps 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 amplifier, you can comfortably use various headphones with all kinds of sensitivities. Safe, secure, and robust power supply The K5 Pro ESS headphone amps 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. For a true high-fidelity sound When it comes to amplification, the K5 Pro ESS DAC is no slouch. The K5 Pro ESS amplifier 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.

What needs to be noted when using K5 Pro ESS? (1) Please adjust the knob to the minimum volume before each listening, then adjust to the volume that suits you. (2) Please insert the power supply and input signal before putting on the headphones. (3) Try not to use inferior cables. Q2.After the K5 Pro ESS is plugged in, it will feel numb to touch the body with your hands. Is this a leakage, is it normal? Because K5 Pro ESS is a Class II device, it is the same as a desktop computer. In some cases, it may feel numb when you touch the body during use. This is normal and does not cause any safety impact. And laptops that are charging will often encounter this problem. K5Pro ESS's adapter has also passed the safety certifications of China, Japan, South Korea, Europe, the United States, and many other countries, and the quality is no problem. It should be noted that the selection of the K5 Pro ESS's power supply is an optimal result after comprehensive consideration of multiple objective phonemes such as product startup, sound quality, indicators, reliability, certification, and cost. The current power adapter, among all the adapters in our experiments, has the lowest noise, the highest startup success rate, and the best indicators. So please rest assured. Q3.Can the headphones out and line out work at the same time? Is the line out output amplitude adjustable? Can it be used as a pre-AMP? The headphones out and line out can work at the same time, and the amplitude can be adjusted. However, the line out output is up to 2Vrms. It is possible to connect an integrated amplifier or an active speaker, but it is not enough to use with the pure power stage amplifier as the preamp. Q4.How to play DSD format when the K5 Pro is connected with the computer? There is an example of the Foobar2000(v1.3.8) installed on Windows computer in our official website, please google "fiio" to check it out. And iOS device users are required to buy the musicapplication program which can support DSD format, such as Audirvana Plus. Q5.Do I need to install a driver to connect it with my computer? Yes, and you can go to our official website to download the driver. Q6.Which "Gain" should I use with my headphones? Choose the gain setting with your earphones such that a comfortable listening volume lies somewhere between 9 and 3 o'clock on the volume knob. Q7.What is the priority level when selecting the Spdif input, if the optical and coaxial input are inserted at the same time? Coaxial input will be the priority. Review: Great Little Desktop Dac/Amp - Full disclosure, I ended up returning this unit because I ended up upgrading to the K9 Pro. So if I returned it, why am I still giving it a rave review? Because, for the money, this is a fantastic DAC/Amp. The amp side provides plenty of power to your headphones. The layout of the unit is very straight forward, simple, yet large potentiometer that controls the power and volume. Flip switches for the gain and the source select and then the headphone input. Very easy to use and a lightweight amp that performs very well. I used this amp to drive Audeze LCD-GX and while that is a pretty efficient headphone, this amp provided lots and lots of amplification. I used the amp in low gain and it still got quite loud with headroom to spare. So there are a few reasons I ended up upgrading to the K9 Pro and returning this model. One, I wanted bluetooth capability; being able to stream music from my phone was something I really wanted. Another was I wanted to be able to use balanced cables in my system. Additionally, I was looking for a solution that would help reduce jitter and pops and noise while I was using the optical SPDIF input. My television is notorious for having all of those things, so I tried many, many solutions, in order to mitigate that, including SPDIF filters, digital reclockers, different cables, HDMI extractors, etc, and what I landed on was the Fiio K9 Pro. So this is not a knock on the K5 Pro because this is a $200 DAC/Amp. Rather versus the K9 Pro which is over 3x the price, at $700, this review is a reason for me to explain, if I didn't want/need any or all of those things, the K5 Pro would absolutely still be in my system because sound quality-wise and usability-wise the K5 Pro is a fantastic value. If you are looking for a high quality sounding DAC/Amp at a great value, this Fiio unit really should be one you should try. Review: Impressive sound quality, more impressive value. - So first off I wanted a K7. I have some harder to drive cans but its basically impossible to find anywhere. desertcart pulled it and several other retailers are all listing it as a pre order but not available yet. Anyway... ended up settling on this or so I thought (spoilers, I don't feel like i settled anymore, it does exactly what I wants at this price point and I'm glad I saved the 50$). I don't mean to say the k7 isn't better, I wouldn't know, but I am gonna say that the K5 drastically outperforms my expectations. I'm a primarily audio-gd user, and due to mishandling it I broke the volume potentiometer on my main rig and so I bought this as a standin. I didn't want something to outperform my main rig, and this manages to get right up to it without quite beating it... and that's saying something because it's over 1000$ in amp and dac. This is an absolutely mind blowing eye watering ear melting value. Now on to the sound: It's mostly hifi. There are parts to this device's presentation that is closer to "the hifi version of something not very hifi but people dig anyway". The other products in the line up feature a bass switch for example, and this definitely has some exaggerated bass but only enough and in just the right way that makes it good. It's not gonna make the staunchest audiophiles happy on their main rig, but it will satisfy anybody who knows they're kinda sorta settling for one reason or another. It's really good value hifi while retaining some elements of consumer appeal (think like, beats by dre). Basically this amp/dac combo is the new king of yeah but it's doing it with x. It sounds this good, it's not the best i've heard, but at 150$ It's a huge wtf. It sounds this good, yeah, I've heard better but not from something this SMALL. The pictures make it seem like it's bigger than it actually is, it's like a 4x5inch thing, really small, about the size of a modern cable modem. This rig does a lot of things like that. New to hifi? Buy it. Seriously, nothing's gonna touch this at it's price point. Can you do better while still maintaining the value? Sure, you've got a lot of room to grow without losing good value for your money but this is probably where great sound really starts. If I was starting out, I'd want to start with this device right here. Need another for your work setup or just your shop or something? Buy it. It won't make your face wrinkle up in disgust, and in some cases it'll make you say whoa, without replacing your prized hifi and it's the cheapest thing I could find with a 6.3mm jack and no bs. Only real complaint I have about this amp/dac combo is what the other reviewer pointed out: there's a deadzone at the start of the volume knob, after you click it on to when you start hearing stuff is a surprisingly large amount of the turn, I'd say 15-20% of the knob is deadzone after the on click then you start hearing it and it rapidly climbs in volume at teh beginning presumably to make up for lost time. I wish there was a touch more nuance in the lower volume levels because I listen primarily quietly, although this does get loud and that serves me well on my work setup because i'm way more likely to listen to something loud and brutal while working. BFG division has gotten me through a lot of shifts, but most of the time I listen quiet and this loses some of the super low end volume range... But it is meant to be used with an intelligent transport of some kind (aka a computer so you can make up for this a bit with your player or system volume, and the volume movement is there in the knob it's just really tight starting out and hard to adjust because of it). The gain switch is nice for medium to higher volumes, however... oh and on the subject of stuff it connects to, I'm using this on linux with no issues. I hope that's useful to somebody. Anyway this review is already obnoxious, take care audiophiles! ## Features - [High-performance DAC&USB decoding chip]: The K5Pro ESS headphone amps achieves new heights in sound quality and comes with a high level of resolution sound.

Unfortunately it did not play nice with my PC on a fresh install. This DAC/AMP replaced a Topping DX3 Pro+ and is an upgrade to the older K5 Pro that I used for 2 years prior to the Topping with an AK chipset. This DAC/AMP has a Sabre ESS chipset and a powerful headphone AMP and sounds amazing with my Hifiman 400se headphones and my 7hz Salnotes Zero IEM's. The unit comes with 3 gain levels and even with high impedance headphones I did not need to use a higher gain. It did take me 2 days to get this up and running correctly and I made the assumption that the unit was DOA. First of all, this unit is plug and play, however on my PC windows set up the bitrate to 32 bit 48000khz. This prevented an output from the DAC/AMP to my headphones. This was fixed easily enough when I went into settings and changed the rate back to 32 bit, 44100khz. After this, everything sounded absolutely fantastic. Shame it took me a couple of days to work out what was wrong. The second issue I had was with the ASIO drivers from Fiio. My recommendation is not to bother using them, as they introduced noise to playback with a faint intermittent background ticking, which was extremely annoying. I thought the unit was faulty, until I removed the drivers and used WASAPI instead of ASIO. Great sound for the money and a terrific headphone amp. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/772436507-fiio-k5pro-ess-amplifier-headphone-amps-stereo-high-resolution-portable](https://www.desertcart.com.ar/products/772436507-fiio-k5pro-ess-amplifier-headphone-amps-stereo-high-resolution-portable) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
