Features & Specs Line Circle

POWERFUL
On the top end of the musical spectrum, the 400M delivers finesse, detail and refinement that can challenge your perception of reality vs. recorded music.
WITHOUT EQUAL
When used in conjunction with the 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.
KEY FEATURES
Of course, key features you’d expect in a MOON product are present such as 12V triggers and an RS-232 port for custom-install environments.
COMPLEMENTARY PRODUCTS
The MOON 390 is multi-function crossover type product that has the function of a modern network player (MiND 2), DAC, preamplifier, headphone amplifier, and phono stage. In other words, it provides the performance you want with the flexibility you need!
LEVEL UP
Add the MOON 860A v2 Power Amplifier will mate seamlessly with any loudspeaker allowing it to reach its full sonic potential, regardless of its load.
