EXEMPLARY DUAL THX AAA AMPLIFIER CIRCUIT DELIVERING AMPLE POWER TO DRIVE ANY HEADPHONE

FiiO K9 Pro ESS not only acts as a high performing DAC but also offers Amplification functions. Equipped with a pair of THX AAA 788+ chips, the K9 Pro ESS provides vivid details and dynamics whether you are using low or high-impedance headphones. The K9 Pro ESS with the THX AAA 788+ chip can output up to 46Vpp transients while driving high-impedance loads and up to an undistorted 2W when pushing low-impedance loads. The embedded THX AAA chip can produce an undistorted 1100mW under a 300ohm load and an undistorted 2100mW under a 32ohm load, 50% higher than the original THXAAA 788 amplifier chips with higher heat dissipation efficiency.

FULLY DIFFERENTIAL AND BALANCED DESIGN WITH A DUAL FEMTOSECOND CLOCK AND SIX-STAGE CIRCUITRY

The K9 Pro ESS is engineered to offer the best audio performance. To achieve this, a fully differential and truly balanced design is utilised for the K9 Pro ESS. Such a design ensures minimal interference between different components to fully maintain all details and the large dynamic swings in music for unmatched sound quality. Differential signals go through the four channels of the DAC, four channels of volume adjustment, and four channels of Amp for a truly balanced design. It also has a six-stage audio circuitry to ensure the users get the best possible sound performance. The analogue and digital circuits have separated paths with partitions for clean performance. Using an ultra-precise clock management system, the K9 Pro ESS can maintain maximum quality no matter the source. Dual asynchronous femtosecond clocks decode USB and Bluetooth sources, while automatic PLL clocks decode optical and coaxial sources.

FAST AND RELIABLE HI-RES BLUETOOTH CONNECTIVITY WITH LOSSLESS MQA DECODING CAPABILITY

Like every aspect of the FiiO K9 Pro ESS, it features the latest in Bluetooth technology to offer Hi-Res quality audio wirelessly. The FiiO K9 Pro ESS employs the Qualcomm QCC 5124 to handle Bluetooth connectivity, with support for formats such as AAC, SBC, LDAC, aptX, aptX LL, aptX HD and aptX Adaptive. This chip ensures that Bluetooth connections are both reliable and quick, satisfying both the low latency needs for games/videos and the high bitrate necessary for high-resolution audio. With the latest technologies found in the K9 Pro ESS, it supports the unfolding of MQA tracks, allowing you to listen to high-resolution audio files that are not only compact but also retain the master-level sound quality that brings you directly into the recording studio.

ADVANCED POWER DELIVERY WITH LDO’S AND PORTIONED CHASSIS DESIGN FOR LINEAR TRANSMISSION

The FiiO K9 Pro ESS features a highly regarded linear power supply. The K9 Pro ESS’s linear power supply, with its low-frequency transformer and 4 massive 4700uF capacitors makes sure that the rest of the system gets abundant clean power for the whole system. The chassis of the K9 Pro ESS uses a portioned layout, wherein not only the power supply and signals are separated, but the analogue signal loop is also put in an independent section, guaranteeing the integrity of the audio signal being processed. The digital portions of the K9 Pro receive power separately from the analogue parts for effective shielding against audio interference between the two circuits. In each stage of the audio circuit, ultra-low-noise LDO is employed for voltage regulation. No expense was spared in ensuring a clean power supply, with the K9 Pro ESS in total having a substantial amount of 20 LDOs.

THREE WAY GAIN SETTINGS WITH ACCURATE VOLUME ADJUSTMENTS BASED ON ADC CURVE RECONSTRUCTION

With the FiiO K9 Pro ESS, you can switch between high, medium and low gain setting to exactly fit your needs when listening to any pair of headphones. Thanks to the pure hardware gain circuit, even when listening at low gain with high sensitivity headphones both dynamic range and musical fidelity remain unaffected. The volume knob in the K9 Pro ESS has been engineered with the ADC curve reconstruction method for volume adjustment in the K9 Pro ESS. This effectively minimises any left-right channel volume imbalances and noise and also results in a smooth change of volume across all levels. The volume knob may seem like a pretty simple component of an amp, but executing it well is crucial to the listening experience.

God-Tier Dac/AMP!

Bought this one after researching a fair bit, and because I'm lazy and want an all-in-one Dac/Amp.
And boy this does not disappoint. INSANELY clean sound, fantastic features like BT/Phone App equalizer. These are great with my ARYA Stealth.

Hey there, thank you for the great review and ratings! So delighted that you are loving your purchase. Hope you had a comfortable shopping experience. Cheers!

Good DAC

I am using this unit as stand alone DAC. XLR O/P is wired to integrated amplifier. RCA O/P is wired to a subwoofer.
Sound quality is fine, but not so musical (w.r.t chord qutest DAC & inbuilt DAC in Mcintosh MA 7200 integrated Amplifier or even bluesound nodeX).
Sounds extremely clean and open but not harsh at all. Provides lots of detail.
BT input works well.
Runs bit hot in DAC mode also.
Not checked headphone o/p. Hence can't comment on that.
It's quite heavy w.r.t it's physical dimension.
Overall very good unit.

We really appreciate the genuine feedback, we'll share your thoughts with the brand as well!

A great VFM flagship DAC/AMP

It is built like a tank! The vertical orientation is a welcome feature which saves a ton of space. This one can drive! Paired with a good HP (I have paired it with Audeze LCD-X), you will transcend into a different plane without having the push the dial to 11. It can easily drive the X without breaking a sweat. There is absolutely zero loss in fedility across a wide range of audio sources (Tidal, Apple Music, Spotify) and is pretty neutral across the spectrum which offers total control over EQ based of your preference. The sound stage with the X is clean and sounds true to source. With a wide gamut of input options available; you will not be limited in connectivity and pairing it up with your equipment. This one is 100% a zero regrets buy.

Hey Phaneesh, thank you so much for the amazing feedback! It means a lot to us. We are so happy to hear that you are loving our products and services.

Clearly punches above its weight

This is really well built. Doesn't look Chi-fi at all. One slight deficiency in the built quality is the volume control, which has a bit of latency from when the knob is turned and when the actual action happens. The sound that is delivered is very clean and detailed. Though it's intended to be very neutral, the sound signature may be a little "warm", but pleasantly warm, If this makes any sense. This complements very well with my Focal Clear and Sennheiser IE600.

Hey Gaurav, thank you so much for the awesome review!
