80 Transistor Matrix for Superior Power and Control

The AMP18 features a complex 80 transistor matrix built from 40 dual transistors. This advanced design provides higher current output and improved control, making it ideal for driving low impedance headphones and demanding audio setups.

Fast Transient Response with Current Feedback Design

Unlike traditional amplifiers that rely on deep negative feedback, the AMP18 uses a cascaded current feedback circuit. This reduces signal delay and avoids transient distortion, ensuring faster response and better detail during dynamic music passages.

Two Stage Amplification for Clean and Accurate Sound

• The AMP18 uses a dual stage amplification system
• The first stage restores audio details with low noise precision
• The second stage boosts current output with linear amplification

This results in clean, accurate sound with strong dynamics and excellent clarity.

Natural and Musical Sound Signature

The complementary output design minimizes distortion and ensures symmetrical signal amplification. This produces a more natural and analog like sound with improved bass depth, midrange richness, and extended highs.

High Power Output for All Headphones

With up to 1740mW per channel at 32 ohms using external power, the AMP18 can easily drive both sensitive IEMs and full size headphones. It delivers strong bass impact and excellent overall control.

Balanced Output for Maximum Performance

The dual 4.4mm balanced outputs provide improved channel separation, lower noise, and higher output power. This ensures a more immersive and detailed listening experience.

Wide Compatibility with iBasso Players

The AMP18 is fully compatible with DX340, DX320, and DX300 players. It integrates seamlessly into the modular system, offering a significant performance upgrade.
