Lyngdorf MXA-8400

The MXA-8400 is the most powerful product from Lyngdorf Audio ever, delivering 8 x 400 watts of ultra-linear and stable power. It incorporates Purifi EIGENTAKT technology with the innovative EIGENTAKT ErrorCorrection (EEC), Lyngdorf Audio’s highly efficient and advanced power supply PowerPerfect, ultra-low-noise and precise analog input stages, and a 4-layer main PCB optimized for the best signal purity and grounding. With this range of features, the MXA-8400 sets new amplifier benchmarks in audio quality, measured performance, and reliability.

Purifi EIGENTAKT technology is the result of extensive research addressing persistent challenges in Class D amplifiers. The patented EIGENTAKT ErrorCorrection (EEC) ensures ultra-high, full-output loop gain (>75dB) in the entire audio band. This produces extremely low Total Harmonic Distortion (THD) at any frequency and any power level, as well as unrivaled low Inter Modulation Distortion (IMD), leading to a highly resolved and stable stereo image unmatched by any amplifier technology or operating class. The result is an incredibly neutral sound performance, with negligible audible noise and no sonic fingerprint.

8 Purifi amplifiers with a combined 3.2 kilowatts of output power and even higher peak power represent extremely high challenges for the power supply, which is often a limiting factor with common multichannel amplifiers. PowerPerfect by Lyngdorf Audio is a highly efficient and advanced power supply. With its integrated Channel Balancing Technology and several protection systems, it provides the best basis for each channel, even with all channels driven. It is so power-efficient and has such a low idle power consumption that the enclosure sufficiently becomes the heatsink, with no noisy fans required. The mains power is decoupled by design, requiring no external power conditioner. It safeguards the speakers from mains-generated noise, represents a gentle load to the mains, and does not introduce noise to other equipment.

The MXA-8400 is assembled to the highest quality standards at Lyngdorf Audio in Denmark, where each unit must pass a 24-hour test with all channels driven and must be measured to meet all specifications. This ensures the ultimate performance and highest reliability.
