Named After Kunlun
The Prologue to iBasso High-End Desktop Devices
Kunlun is the mythological abode of celestial beings and symbolises utmost reverence. The iBasso Kunlun is named in this spirit — and represents our relentless pursuit of high-end sound quality.
As a high-end GaN desktop headphone amplifier, Kunlun integrates cutting-edge amplification technology and embodies a pioneering spirit of technological exploration and advancement.
Pioneering GaN Desktop Amplifier
The Summit of Sound Quality
As the industry’s first to apply GaN in a very affordable desktop headphone amplifier, Kunlun signifies iBasso’s exploration of front-line technology. GaN FETs boast electron mobility of up to 2000 cm²/Vs, surpassing traditional MOSFETs and silicon transistors, demonstrating higher electron velocities and lower conduction losses at high frequencies.
GaN FETs have a significantly smaller total parasitic Miller charge (QGD) compared to equivalent Rds(on) power MOSFETs, enabling faster switching speeds. When applied to audio amplification, this results in improved transient response, dynamic performance, and control.
High Current, Low Internal Resistance
Precision in Every Detail
GaN’s ultra-low Rds(on) allows higher current drive capability. As a powerful desktop amp, Kunlun’s output impedance is as low as 0.12Ω and is capable of accurately driving low-impedance in-ear monitors, delivering a dynamic, layered sound. Its control strength is like a towering robot performing a delicate ballet.
Equipped with 40 High-Performance Transistors
A Powerful Lineup Delivers Overwhelming Performance
Kunlun utilises premium components: 8 power transistors in the output stage and a 16×2 configuration in the drive stage, totalling 32 transistors to build a super-large discrete amplification system.
Compared to traditional op-amp architectures, Kunlun’s current output capacity is several times higher, offering greater dynamic reserve and headroom, with detailed clarity while delivering both powerful and delicate high-quality sound equally.
7400mW + 7400mW @ 32Ω
Conquering All Challenges
In balanced mode at a 32Ω load, each channel delivers up to 7400mW, enough to drive high-impedance, low-sensitivity full-size headphones. Kunlun exhibits a robust dynamic range with a rich, layered soundstage.
Linear Power Supply
Rejecting Digital Rectification, Kunlun Returns to Analog Aesthetics
Kunlun abandons switching power supplies, opting for linear transformers with high-quality voltage regulators. This ensures smoother power delivery and a lower noise floor.
The linear power supply keeps the entire analog signal chain stable and quiet while presenting micro-textures and details with near “zero distortion”, enhancing the analog flow of music.
Comprehensive DC Protection
A Firewall For Your Headphones
The built-in DC protection circuit detects abnormal DC components and immediately cuts off output power, safeguarding your headphones from damage and providing full protection for audiophiles.
Cutting-edge Parts Selection
Investing Heavily For Superior Sound
Every component in Kunlun is carefully selected, adhering to the philosophy of “in pursuit of perfection”. The device uses eight high-performance GaN FETs and a large number of audiophile-grade electrolytic and film capacitors, ensuring a stable power supply and extremely low distortion, resulting in a clean, delicate, warm, and engaging sound.
Analog Adjustment, Digital Control
Making Ease of Use Second Nature
Kunlun employs high-grade TI Texas Instruments volume control chips. At any volume, the left and right channels maintain high consistency, with linear and delicate adjustments.
At the same time, Kunlun utilises an analog potentiometer for control, allowing users to experience the tactile feeling of turning a physical analog potentiometer.
A three-position stepped potentiometer allows hardware gain adjustment, matching various headphone sensitivities while effectively suppressing noise and distortion, keeping the sound pure and natural.
CNC Aluminum Chassis
Exudes a Sense of Luxury
The chassis is made with precision CNC machining of aluminum alloy, with anodized surface treatment for a hard, scratch-resistant surface. Its sleek, classic appearance exudes a refined metallic texture.
The top allows for good heat dissipation and, combined with an optimised internal design, assures stable and efficient operation under high-load conditions, helping prevent overheating that can affect sound.
