Implements 80-Transistor Matrix Architecture For High Current Output & Driving Power

iBasso AMP18 implements an advanced 80-transistor matrix formed by 40 dual transistors, overcoming the spatial limitations of compact AMP card designs. Supported by an optimised circuit layout and high-quality components, this architecture delivers higher current output, improved low-impedance compatibility, and enhanced overall performance.

Integrates Cascaded Current Feedback Circuit For Precise Transient Response

iBasso AMP18 integrates a cascaded current feedback circuit that avoids transient distortion caused by traditional large-loop deep negative feedback designs. This ensures faster signal transmission, preserving dynamic range and delivering clean, impactful reproduction of sudden audio transients without loss of detail.

Employs Two-Stage Amplification Architecture For Accurate Signal Restoration

iBasso AMP18 employs a two-stage amplification structure where operational amplifiers and transistors work in tandem to restore audio signal details with precision. The first stage ensures low-noise accuracy, while the second stage boosts drive capability, preventing signal attenuation and maintaining clarity across the frequency range.

Incorporates Complementary Output Circuit For Reduced Distortion & Natural Output

iBasso AMP18 incorporates a complementary output circuit that minimises asymmetrical distortion commonly found in conventional transistor stages. By enabling symmetrical amplification of positive and negative waveforms, it ensures complete waveform reproduction, reducing clipping and delivering a more natural and refined listening experience.

Supports DC 12V External Power For High Voltage Swing & Enhanced Output Power

iBasso AMP18 supports an external DC 12V power supply, enabling a ±12V voltage swing and delivering up to 1740mW + 1740mW @ 32Ω in super gain mode. This substantial power output allows it to drive a wide range of headphones and IEMs with authority, producing deep bass, full-bodied mids, and extended treble performance.

Equips Dual 4.4mm Balanced Outputs With Dedicated Line-Out Functionality

iBasso AMP18 equips dual 4.4mm balanced outputs that function as both headphone out and dedicated line-out. The balanced interface enhances compatibility and driving performance, while the dedicated line-out provides a clean signal source for integration into larger HiFi systems.

Ensures Broad Compatibility With DX300, DX320 & DX340 Series Players

iBasso AMP18 ensures seamless compatibility with DX300, DX320, and DX340 digital audio players, delivering a significant upgrade in overall performance. When paired with supported devices, it revitalises the sound output, offering a more dynamic and engaging listening experience, with note that DC 12V support requires DX340 firmware updates while DX300 and DX320 do not support external 12V power input.
