Know before you buy
Yes. The amplifier is designed to handle demanding loads, delivering 400 watts into 8 ohms, 800 watts into 4 ohms, and doubling again to 1,600 watts into 2 ohms, ensuring it maintains control over virtually any speaker.
Yes, Dan D'Agostino Master Audio Systems offers an upgrade path for previous Momentum monoblock generations. This allows owners to incorporate the new transformer, input stage, and bias circuitry advancements without replacing the entire chassis.
The updated transformer design provides over 50% more current output compared to previous iterations. This increased current capacity allows the amplifier to respond more dynamically to complex musical transients and maintain stability under heavy loads.
By increasing the Class A bias, the amplifier operates in its most linear range for a larger portion of its power output. This results in improved sonic purity, greater detail, and a more refined presentation at typical listening levels.
The M400 MxV utilizes proprietary Venturi-style copper heatsinks, which are highly efficient at dissipating heat. While it is a powerful amplifier that runs warm, these heatsinks allow for effective cooling even in high-performance setups.
The amplifier features both balanced XLR and RCA inputs. For the best performance and noise rejection, we recommend using the balanced XLR input, which takes full advantage of the amplifier's fully complementary circuit design.
