iBasso AMP17 Balanced Amplifier Card with GaN technology, dedicated 4.4mm PO and LO outputs, and up to 1900mW power delivery. This module brings first-ever Gallium Nitride FETs combined with discrete transistors for superior efficiency and dynamics in portable audio. It offers clean technical performance with low output impedance and excellent measurements for demanding headphones.
About iBasso AMP17
The iBasso AMP17 brings advanced Gallium Nitride technology to portable audio amplification for the first time. This innovative combination of GaN FETs with discrete transistors creates a discrete Class AB balanced design that delivers fast transients and excellent efficiency. Users gain superior power delivery and cleaner signal handling that makes demanding headphones come alive with authority while keeping background noise extremely low.
Compatibility stands out as a major strength of this amplifier card. It works perfectly with the DX340 and extends support to the older DX320 and DX300 models without issues. The dedicated 4.4mm balanced headphone output pairs with a separate 4.4mm balanced line output so the device can serve both personal listening and external system integration needs. This flexibility helps owners maximize their existing DAP investment across different setups.
Power output reaches impressive levels that handle even tough headphone loads with ease. Battery operation provides 1030mW plus 1030mW at 32 ohms while the external 12V DC input unlocks Super Gain mode for up to 1900mW plus 1900mW at the same load. The consistently low 1.1 ohm output impedance ensures precise control over a wide range of headphones and IEMs without unwanted damping effects.
Technical performance metrics highlight the card’s precision engineering. It achieves a THD+N of -116dB with no load and -110dB at 600 ohms along with a 120dB dynamic range and 122dB SNR. Crosstalk stays at an excellent -117dB and the frequency response covers 10Hz to 40kHz within tight ±0.5dB tolerance. The line out delivers adjustable voltage levels reaching 3.0Vrms in high gain for clean external amplification.

Reviews
Power feels endless when I plug in my demanding headphones. The soundstage opens up wide with precise imaging that makes instruments feel alive and separate. Bass hits hard yet stays controlled and the overall clarity surprises me every session.
Switching to this card improved dynamics noticeably on my DX340. Details emerge cleanly without harshness and the background stays pitch black. I enjoy longer listening sessions because the presentation stays engaging and fatigue free.
Compatibility with my older DAP works flawlessly and the dedicated line out simplifies connecting to my desktop setup. Transients feel lightning quick while maintaining natural tone. This upgrade brings new life to my entire headphone collection.
