Simaudio Neo 400M Power Amplifier

The Neo 400M is the ultimate Neo-class Power Amplifier.
Extremely powerful, yet with a delicacy and articulation of the best amplifiers out there, the Neo 400M can take on virtually any loudspeaker you connect it to. Delivering a bottom-end slam, with authority and weight to the foundation of the music, it will transport you into a live concert environment. On the top end of the musical spectrum, the Neo 400M delivers finesse, detail and refinement that can challenge your perception of reality vs. recorded music.
When used in conjunction with the Neo 350P Preamplifier, the results are without equal. There isn't a more refined combination at this price point. An ultimate combination for the discerning music lover, and for those who like to listen at higher sound levels.
Of course, key features you'd expect in a MOON Neo Series product are present such as 12V triggers and an RS-232 port for custom-install environments.
Note: Available finishes are dependant on location.
