Overview

The Lyngdorf SDA-2400 is a high-performance stereo power amplifier designed to integrate seamlessly into virtually any system—traditional hi-fi, multichannel setups, or even directly with media players and streamers. With both digital and analog inputs, it’s the ideal choice for installations demanding precision, quiet operation, and powerful output.

Flexible, powerful, and remarkably quiet.

Unlike conventional Class D amplifiers, the SDA-2400 employs Lyngdorf’s advanced PWM technology with patented switching speed optimization, delivering ultra-low and linear distortion. The result is an amplifier with a clean, transparent sound and an exceptional signal-to-noise ratio—ready to power any speakers with confidence and clarity.
