iBasso AMP17 GaN & Discrete Transistor Balanced Amp Card for DX300 Series

Exceptional GaN Discrete Balanced Amp Card for High-End Portables The iBasso AMP17 marks a breakthrough in portable amplification by incorporating Gallium Nitride (GaN) FETs alongside precision discrete transistors. Designed exclusively for the DX300, DX320, and flagship DX340 digital audio players, this amp card delivers unmatched performance in a compact, modular format. As the first GaN‑based headphone amp card in iBasso’s lineup, it offers ultra-fast switching, minimal conduction loss, and significantly enhanced transient response. Whether you're powering low-impedance IEMs or demanding full-size headphones, the AMP17 ensures crisp, layered audio with rock-solid stability even under intense musical passages. High Power & Low Impedance:With its 4.4 mm balanced output, the AMP17 provides up to 1030 mW per channel on battery and an astonishing 1900 mW per channel at 32 Ω when powered by an external 12 V DC adapter—ideal for high-impedance headphones or immersive listening sessions. Audio Precision & Low Distortion:Engineered to achieve a frequency response of 10 Hz–40 kHz, an SNR of 122 dB, and THD N of –116 dB (no load), this amp card elevates sound detail, clarity, and dynamic range. Coupled with Advanced GaN Benefits:GaN transistors offer up to 2000 cm²/V·s electron mobility—far superior to silicon devices—yielding faster switching, reduced Miller capacitance, and enhanced control over zero-crossing. These attributes reduce distortion and ripple interference, offering clean, analog-like sound with airy soundstage and muscular dynamics. Modular Compatibility:The AMP17 seamlessly integrates with iBasso’s modular AMP card system. It’s fully compatible with DX300 and DX320 but requires external 12 V DC power only on the DX340 for super‑gain mode. The logic and interface remain identical to stock amp modules, ensuring a smooth and intuitive user experience. Why Choose AMP17:This amp card is ideal for audiophiles who demand extreme performance in a portable format—whether for accurate mastering, detailed listening, or powering flagship headphones. The combination of GaN and discrete circuitry makes the AMP17 a technological leap forward in portable audio amplification.
