Mille power amplifiers are born to fully enhance the outstanding performance of the Mille speakers. The new ADC (ADVANCED D-CLASS TECHNOLOGY) ensures pure listening pleasure while keeping a compact size with unmatched power efficiency. The heat sink, engineered with double technology, extrusion and aluminium die-castingenables the Mille Power amplifiers to work constantly at full power without ever overheating, further maximizing thermal efficiency. The Hertzaudio car amplifier ML Power 4 (4 x 250 W 2 Ω)is the obvious choice for a top level front-rear Mille system.
