Aetherium-500

The ClefSonic Reference Monoblock is a high-current Class AB power amplifier designed for serious loudspeaker control, effortless dynamics, and a refined analog listening experience.

Built around a massive 1600 VA toroidal transformer and a 200,000 µF capacitor bank, the amplifier delivers the kind of reserve power needed for demanding loudspeakers and complex musical passages. The goal is not just high wattage, but stability, grip, and musical authority.

Its 10-pair output stage provides strong current delivery, while the Class AB topology keeps the sound powerful, controlled, and naturally expressive. The front-mounted analog VU display gives the amplifier a traditional high-end character, combining old-school visual charm with modern engineering muscle.

Balanced XLR and unbalanced RCA inputs make the amplifier easy to integrate into both professional and high-end home audio systems. The heavy aluminium chassis, finished in piano black, gives the unit a clean, luxurious presence while helping mechanical stability and long-term durability.

This is a monoblock amplifier built for listeners who want scale, silence, control, and that classic feeling of real hardware doing real work — no shortcuts, no plastic-fantastic nonsense.
