Description

Heralding a New Era of Portable GaN Application
In the realm of high-end portable audio devices, iBasso once again leads the industry. The AMP17 marks the first application of gallium nitride (GaN) in the design for portable headphone amplifiers. Compared to traditional MOSFETs or bipolar transistors, GaNFETs boast an electron mobility of up to 2000 cm/V•s, enabling higher electron velocities and lower conduction losses at high frequencies.
The total Miller charge (QGD) of GaNFETs is significantly lower than that of power MOSFETs with equivalent on-resistance. This characteristic facilitates faster switching speeds, which, when employed in audio amplifiers, results in enhanced transient response, dynamic range, and absolute control precision.
High Current Output and Low Internal Resistance
GaNFET features exceptionally low internal resistance, allowing for higher drive currents. Coupled with the AMP17’s low output impedance architecture, this enables precise driving of various low-impedance headphones, delivering a sound that is layered, dynamic, and highly detailed. Even under complex, high-encoding or high-intensity transient signals, the AMP17 remains rock solid, maintaining complete detail, clear rhythm, and delivering an experience that is both stable and impactful.

100 Step JRC Control
The 100 step JRC volume control not only adjusts the volume but also simultaneously reduces the potential noise of the vacuum tubes. This effectively minimizes the background noise.
