Overview
Ludicrous Power Levels
At 400 watts per channel x 4 @ 2 Ohms and 200 Watts x 4 @ 4 Ohms, this amplifier hits ludicrous levels of power. The difference between this amplifier and other high-rated amplifiers on the market though is the design quality and sound quality. The Euphoria Expert series of amplifiers are highly refined works of art from an engineering standpoint. The EXM400.4 is a solidly built unit with all of the right components to deliver concert-level performance for many years.
