SIX ACOUSTIC X 400 GanFet Integrated Amplifier

Description

A Game Changer in Audio Engineering

There is currently nothing in the audio marketplace that sounds like this for the price. The X400 bridges the gap between classic analog warmth and modern digital efficiency. By utilizing advanced Gallium Nitride Field Effect Transistors (GaN FET), the X400 operates in Class D but creates a much faster, wider frequency response. This technology provides the detail, speed, and dynamics usually reserved for high-end tube amplifiers, all within a compact, cool-running chassis.

Uncompromising Power and Configuration

Designed as Dual Mono Amplifiers, the X400 ensures total channel separation and precise imaging. It delivers a robust 125 Watts RMS per Channel at 8 Ohms and doubles down to 250 Watts RMS at 4 Ohms, ensuring it can drive even demanding speakers with authority.

Versatile Connectivity

Whether you are connecting a turntable preamp, a DAC, or streaming wirelessly, the X400 is ready. It features high-quality Bluetooth aptX for good-quality wireless streaming, along with a full suite of analog inputs including two pairs of RCAs and a pair of balanced XLR inputs.
