Truly Balanced and Hi-Res Certified DAC & Amp

FiiO's K series line-up holds some of the most powerful DAC & Amps, like the K9 Pro, K9 Pro ESS, and K7. Building on its reputation FiiO takes great pleasure in introducing its all-new versatile Desktop DAC & Amp + Preamp - the K7. The FiiO K7 is a "truly" balanced headphone amplifier with THX AAA 788+ amp technology incorporated into its circuitry.

Dual AK4493SEQ AKM DAC Chips

FiiO, to take the performance levels of the K7 to new heights, has included dual DAC chips from AKM technologies AK4493SEQ. The AK4493SEQ is a stereo premium 32-bit DAC with VELVET SOUND™ technology, achieving industry-leading low-level distortion characteristics and a wide dynamic range. The K7 with AK4493SEQ under its belly supports sampling rates PCM 384kHz-32bit/DSD256 (USB DAC), PCM 192kHz-24bit (COAX), and PCM 96KHz-24bit (OPT) ideal for a high-resolution audio source playback.

THX Amplification Technology

FiiO, for its amplification circuit, decided to use the same THX AAA 788+ amplifier technology as the K9 Pro. The FiiO K7 has an output power of 560mW in a 300-ohm load and 2000mW at 32-ohms. This design ensures both low and high-impedance headphones are powered sufficiently.

Two-Level Gain Settings

K7 has two gain-level settings to have a suitable listening volume. The high and low hardware gain levels allow you to easily adjust the K7 to handle headphones of various impedances and sensitivities for a rich and consistent listening experience. Thanks to ADC curve reconstruction, experience a smooth 112 steps of adjustable volume free of channel imbalances and noise - ensuring that every note reproduced is natural and precise.

Bluetooth Connectivity

The FiiO K7 is now available in a new version that features Bluetooth connectivity, known as the FiiO K7 BT. This variant has the latest QCC5124 Bluetooth chip with Bluetooth v5.1 allowing for wireless audio playback from smartphones and tablets. Additionally, it is compatible with high-quality transmission codecs such as aptX Adaptive, aptX HD, and LDAC, delivering CD-quality sound or higher in wireless mode.

Exceptional Power Supply Design

The K7's power design consists of numerous stages, with low-noise LDOs (Low dropout regulators) controlling each stage's voltage. Feeding this power design is an external 12V switching power supply. Overall, the K7's power design provides clean power for an exceptional listening experience. The K7 has a six-stage audio circuit with truly balanced analogue and digital sections – which helps to reduce crosstalk and reproduce music as the artists intended.

The K7 has a six-stage audio circuit with truly balanced analogue and digital sections – which helps to reduce crosstalk and reproduce music as the artists intended. 

Numerous Inputs & Outputs 

FiiO has designed the K7 with numerous input/output capabilities. It contains USB, optical, coaxial, and RCA as inputs and 6.35mm single-ended and 4.4mm balanced as outputs. You can easily switch between three different "outputs" with just one click. One touch of a handy key allows you to switch between 3 output modes (for use with headphones, with speakers, or use as a DAC). One key controls switching between the "4" different inputs, with a flowing light effect to indicate when the input has "switched" and is ready.

All-Aluminium Alloy Construction

The K7 features an all-aluminium alloy construction, carefully finished with CNC and other processes. Its elegant black colour is exquisitely complimented by the gold accents of the THX and Hi-Res Audio badges, and it has a "truly" opulent appearance. The K7 features a minimalistic design that only measures 55mm thick and with a footprint of less than 1/3 of an A4-sized sheet of paper – allowing it to fit perfectly on modern desks.

Intelligent Protection System

FiiO has incorporated multiple intelligent protection systems into the K7 for you to experience worry-free listening. The FiiO K7 is consistent inside and out for you to experience jitter-free audio. "Overheating," overload, and DC protection systems ensure that the K7 always operates at its best, so you can enjoy an unrivalled listening experience in multiple scenarios.

Dual Clock Management

The left and right audio channels have an effective, high-performing AK4493SEQ. Dual clock management used by the XMOS XUF208 decoder chip easily handles diverse music formats. You can rediscover your music with accurate "timbre" and rich and delicate overall sound.

RGB Indicator Lights

The RGB indicator lights provide a distinctive light flow effect while turning ON or OFF or switching inputs, and they can display both single colours and mixed colours. Dazzling and vivid light effects give your desk some much-needed spice.

4.4mm Pentaconn Headphone Jack

You can connect your most power-demanding headphones or IEMs with 4.4mm Pentaconn termination. The Balanced connection decreases crosstalk and interference caused by the balanced output configuration resulting in improved audio signal integrity. As a result, the sound is reproduced with improved channel separation and increased dynamic range, making it cleaner and more accurate.

6.35mm Headphone Jack

This is the most commonly found headphone jack with which you can pair your less power-demanding headphones. It is known for its robust construction, making it durable and reliable for prolonged use. The larger size of the jack provides a secure connection that is less prone to accidental disconnection or damage, ensuring a stable audio signal.

Smooth & Responsive  Volume Knob

The volume knob on the FiiO K7 is tactile and responsive. With a smooth rotation, you can effortlessly adjust the volume to your desired level, giving you precise control over the sound output.

K7 had hit it right out of the park as soon as it had launched. Its versatility and sound quality are just top-notch. Every note resonates with breathtaking clarity. I have thoroughly enjoyed listening to music on the K7, and I am sure you will do too as soon as you get your hands on it.

It is a ‘hard to resist’ package where the K7 truly bangs for the buck and has high versatility for pairing. That makes it one of the most delightful FiiO products I have experienced so far.
I really like the K7 and I congratulate FiiO for their amazing job. If you need a solid, powerful DAC & AMP for your headphones and you are on a budget, the K7 can make you very happy.
A lot of volume adjustment range for sensitive IEMs, Extract the most sound quality out of your IEMs, Balanced and natural sound signature, Really balanced and powerful headphone amplifier.
If you want to turn your workstation into a high-quality listening area, you could do a lot worse than check out the FiiO K7. Detailed, informative and unified sound, Unflustered by lower-res audio files.
The K7 is another solid product from FiiO that impressed me with its versatility in terms of hardware features, compatibility and overall sound performance that pairs pretty well with both IEMs & Headphones.

A dac/amp that gives a feeling of satisfaction

I have used many dac/amps in a very short span of time to find the right audio gear for me. At last I feel satisfied. The design and operation of the device is very good. It would be very difficult to exceed sound quality of this device in this budget by competitors. Fiio drivers r required in windows, a reminder to users. Aimp player or audirvana player for DSD playback can be used in windows with Fiio ASIO driver.
The sound signature is neutral with clear treble but the 3.5mm port lacks air and sparkle little bit. SoundStage is very narrow and personal in 3.5mm port when paired with iems. The sound signature is very authoritative and powerfully detailed on the leaner side. Treble is sharp but fortunately there is smoothness. The bass is very punchy and powerful but not loosing control, just right in quantity. Excellent almost natural sounding dac-amp. Just a bit on the leaner side.

4.4mm plug empowers the amp and brings out the amps tuning signature more. More treble energy, wider soundstage, extreme control & power in bass punch, faster decay. Presence of sparkle/air.

Volume control is quite good:- 25% power present in 70% of the dial. 75% power is present in the remaining 30% of dial making volume control easy.

Cons:- No balanced line in, can't modify digital PCM filters, single ended lacks sound stage therefore good for external speakers not iems. High gain and low gain modes have different Treble performance. This k7 is heavily tuned for Fiio FD5/7. I know Fd7 has muddy characteristic sound which many Youtube reviews even agree. But this K7 has too much energy in lower and mid treble region which is meant to empower the FD7. And lower mids are a touch thinner which is also purposefully done for FD5/7. Also recording noises get amplified to audible levels, which other dacs mostly suppress.

I want to add that my review is written over a period of 3 weeks, and I have tested many Iems/headphones in the mean time and came to this conclusion that SYNERGY is the most important factor to consider while buying audio equipment.

Synergy info:- Hifiman R9(silver plated balanced cable), IT01x(very slightly the treble feels inaccurate), Moondrop Aria (Bass punch can be hurting). Absolute no to any clarity enhancing/high resolving iems like moondrop chu etc. Probably will sound good with Fiio FD7(not tested with K7 yet) but I have listened to them before

Lastly it's good overall but sound signature could have been more musical if timbre and mids would have received a little more emphasis. Feels dry with my current iem. The 788+ is very very good but the dac implementation is not upto standard. Therefore k7 feels raw power and grunt without delicate delivery

Thanks a lot for your detailed and genuine feedback, we're glad that you have such positive thoughts about the product and we'll share your thoughts with the brand as well. It'll also help our fellow customers to make the right choice!

Worthy Investment

Recently bought Hifiman Ananda SE (through HPZ - great product and delivery experience), and needed a more powerful amplifier. I have an EarMen Tr-Amp which is very well capable of driving it, but planars are supposed to scale better with more power, and hence the purchase. Initially, I wanted to go with XDuoo XA-10, but decided against it in the end due to the concerns on loose power terminal and its tendency to run hot.

Fiio K7 is very good for its price, sounds pretty much uncoloured and has got my favourite AKM DAC. I'm not a fan of ESS (in Tr-Amp), and I'm happy that I got one with AKM in this price bracket.

Sound quality is nice, airy, not too bright, has adequate thump as called for by the music, and works fine with sensitive IEMs like my IE200 or Final A5000. Volume control isn't linear - that's one to nit pick, but it does result in avoiding channel imbalance at all volume levels, as advertised. All in all, happy with the product.

Now, coming to the delivery, I have no clue why HPZ chose Smartr as their courier partner instead of the tried and tested BlueDart. They were sitting on my package for 2 days, not even attempting to call me, let alone deliver it. I had to find my way through them and their warehouse by calling their customer support, and drove myself there to pickup the package. I was told that they didn't get a delivery person to send it across - how convenient, and why do they run a delivery business in the first place without a contingency. HPZ - if you're trying to cut down on the delivery charges, please give me an option, and I'd happily pay for the shipping and go with a reliable courier service. Left a bad taste, despite liking the product, and I'd now think twice before ordering a pricey product from HPZ.

Widening of Horizons!

FiiO K7 has opened up the soundstage of my aging Audio-Technica ATH-M50, Bose QuietComfort 25 and KZ-ZSN Pro X. I've started to hear hitherto unheard of elements in the very same music files of all genres and all qualities that I've been listening to for years. I'm more impressed with the mids and highs with the voices coming out more clear and rounded. The difference in bass is not all that pronounced but still the bass guitar riffs have become more prominent. I'm thinking in terms of getting a new pair of headphones of at least 250 Ohms impedance to realise the full potential of the device. I'm perfectly happy with the purchase.

Hey there, nothing makes us happier than knowing you loved your purchase, hope you had a comfortable shopping experience and thank you for the great review and ratings!
