IBASSO AMP17 Amplifier Module for DAP DX340

The iBasso AMP17 is an amplifier module specially designed to accompany the brand's DX340 DAP, providing it with GaNFET transistor amplification for an impressive total power output of 1900mW+1900mW at 32Ω.

iBasso AMP17: GaNFET transistors

The AMP17 amplifier module uses a topology based on GaNFET transistors, whose internal resistance is significantly lower than that of traditional MOSFETs, allowing higher currents to pass without premature compression. This feature, enhanced by the module's low-impedance architecture, translates into the ability to maintain stable and extended output dynamics, even with very low-impedance headphones that require instantaneous and demanding current. Beyond raw power, this approach ensures more responsive reproduction, with bass response and transient articulation preserved even at sustained volume levels.

This electrical efficiency is accompanied by a switching frequency significantly higher than that of conventional MOSFET architectures, allowing switching residues to be pushed well beyond the useful audio band. By mechanically reducing interference related to signal oscillation, the module limits analogue plane pollution, contributing to a more stable sound stage and clearer micro-dynamics. This control of background noise directly benefits extended listening sessions, particularly with transducers that are sensitive to phase variations and interstitial silence.
