Six Core Advantages:

 

Deliver Flagship-Grade Audio for Entry-Level Users

① Cutting-edge GaN Technology, Max Efficiency & Longer Service Life

Adopts original Infineon CoolGaN™ discrete power solution, paired with dedicated controller and gate driver, achieving overall unit efficiency of over 93%.

It saves nearly half power compared with traditional Class AB amplifiers, and delivers obvious efficiency improvement over ordinary silicon-based Class D amps. It consumes less energy during long-hour operation, slows down component aging and extends service life.

⸻

② Ultra-low Distortion of 0.009%, Sound Quality Matches High-end Class A Amps

Break the stereotype that Class D amplifiers deliver inferior sound to Class A units. Benefiting from GaN’s ultra-fast switching speed and zero reverse recovery characteristic, the unit reaches THD+N as low as 0.009%, SNR up to 120dB and dynamic range of 118dB.

Transparent and delicate treble without harshness, full natural midrange, light and clean bass response. It maintains clear sound under large dynamic signals, provides warm and pleasant listening experience and restores the original texture of recordings.

⸻

③ Ultra-low Heat Generation, Compact Chassis with High Power Output

GaN devices feature extremely low switching loss; nearly all electric power is converted into audio output, greatly cutting waste heat.

No bulky large-area heat sinks required as traditional amplifiers. The compact lightweight body fits easily on desks, bookshelves and AV cabinets without occupying much space.

Only slightly warm even under long-term full-power operation, no more scorching hot amplifiers — perfect for listening in summer.

⸻

④ Dual Power Modes, One Unit Replaces Two

Supports stereo and bridged modes to flexibly fit various scenarios:

Stereo Mode (2Ω): 200W per channel (4Ω), effortlessly drives all bookshelf speakers and desktop Hi-Fi systems, with high channel separation and precise soundstage positioning.

Bridged Mode (BTL): 500W single-channel output (4Ω). High power handles low-sensitivity floor-standing speakers and passive subwoofers, fully driving large cabinets and delivering effortless impact on explosive soundtracks.

⑤ Full Professional Inputs for Flexible System Building

Dual input ports: unbalanced RCA and balanced XLR. Balanced transmission effectively suppresses cable interference and background noise, unlocking superior sound when paired with high-end DACs and preamps.

Built-in 12V trigger port enables power sync with preamps and players for easier home AV system setup.

⸻

⑥ Five Independent Protection Circuits for Safe Operation

Each amplifier module is equipped with independent protection against overcurrent, overvoltage, under voltage, overheating, and DC offset.

It automatically shuts down to protect equipment under short circuit, overload, overheat, and other faults, preventing costly speaker damage from disoperation, safe for home and studio use.

 

Why are traditional power amplifiers never fully satisfying?

 

Issue 1: Traditional Class AB Power Amplifier

Bulky size, hot surface when working, low efficiency; long-hour operation consumes much electricity and damages the unit.

 

Issue 2: Ordinary Silicon-based Class D Power Amplifier

Limited switching speed, prone to high-frequency distortion, dry and cold sound performance, unable to match the sound quality of high-end models.

 

Issue 3: GaN Power Amplifiers on the Market

International brands cost thousands of RMB; high technical threshold, with no high-quality cost-effective options available.

 

Issue 4: High-power Amplifiers Occupy Large Space

Limited placement space and bulky chassis; long-term cooling fan noise can affect the listening experience.

 

Issue 5: Unsolvable Overheating of Class A Amplifier

High switching loss, bulky heat sinks are mandatory, which makes slim and compact design impossible.
