Know before you buy
This design approach processes the audio signal in a way that significantly reduces noise and interference. By cancelling out common-mode distortion, it delivers a cleaner, more transparent soundstage and improved clarity compared to standard single-ended designs.
Yes. With 800 watts into 8 ohms and 1600 watts into 4 ohms, the 880M is designed to handle virtually any speaker load. Its high damping factor and robust power supply ensure it maintains control over even the most demanding drivers.
Lynx technology eliminates global feedback, which allows the amplifier to react to the music signal in real-time. This results in a more natural, accurate reproduction of the original recording without the phase errors often introduced by feedback loops.
The 880M operates in Class A for the first 10 watts of power, providing the refined, smooth performance associated with that topology. Beyond that point, it transitions into Class AB to provide the massive current and headroom required for high-volume peaks.
The 880M includes a sophisticated self-diagnostic system that continuously monitors for potential issues. It will automatically detect overheating or the presence of DC in the input signal and shut down to prevent damage to your equipment.
Each amplifier weighs 144 pounds, so you will need a dedicated, heavy-duty audio rack or a stable, reinforced surface. Ensure your furniture is rated to support this weight and that you have adequate ventilation space around the units to manage heat dissipation.
