The AMP17 marks the first application of gallium nitride (GaN) in the design for portable headphone amplifiers.\u003c\/p\u003e\n\u003cp\u003eCompared 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eHigh Current Output and Low Internal Resistance\u003c\/h3\u003e\n\u003cp\u003eGaNFET 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.\u003c\/p\u003e\n\u003ch3\u003eSignificant Suppression of Ripple Interference\u003c\/h3\u003e\n\u003cp\u003eGallium nitrides support higher operating frequencies, endowing the AMP17 with an expansive, responsive, frequency bandwidth. Even the finest high-frequency details are faithfully reproduced. Compared to traditional headphone amplifier solutions, the integration of GaNs markedly reduces interference caused by inductor ripple currents on the audio signal. The resulting imaging is crisp, analog, and naturally articulated.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/9255\/5595\/files\/ibasso-amp17-lifestyle-two.webp?v=1752859361\" width=\"2048\" height=\"2048\" alt=\"iBasso AMP17 amp card coming out of DX340 DAP with screws out partly cut off at angle from top left corner on cotton material\"\u003e\u003c\/p\u003e\n\u003ch3\u003eRapid Response and Reduced Distortion\u003c\/h3\u003e\n\u003cp\u003eGaN switch speeds surpass those of conventional silicon-based MOSFETs by several tens of times. This advantage allows the AMP17 to achieve near seamless zero-cross switching. The output waveform approaches an ideal form, rendering the tonal quality more transparent and natural. Under such low-distortion conditions, musical nuances emerge vividly, with every delicate emotional detail precisely restored, delivering an immense and immersive listening experience.\u003c\/p\u003e\n\u003ch3\u003ePower Supply\u003c\/h3\u003e\n\u003cp\u003eBuilding upon iBasso's latest generation of external power supply designs, the AMP17 supports a 12V DC input. In super-gain mode, it unleashes AMP17's full potential, delivering a formidable output power of 1900mW + 1900mW at 320. Whether driving full-size dynamic headphones or flagship lEMs, the AMP17 provides a rich, powerful sound. Its transient response is swift, and the bass is deep, rich, and impactful.\u003c\/p\u003e\n\u003ch3\u003eFull Support for DX300 Series\u003c\/h3\u003e\n\u003cp\u003eThe AMP17 not only supports the DX340 but is also compatible with the DX300 and DX320 players.
