A100K Power Amplifier

A100K  –  Mosfet Power Amplifier

The A100K is a dual mono power amplifier, equipped with a new generation of mosfets, engineered and optimized for audio use only.

Technical simplicity and selection of components are the best ingredients of transparency and details in every musical reproduction, in the best Italian audio philosophy.

At every listening level the A100K gives an impressive three-dimensional reconstruction, solid  and controlled bass range, with human voice always well present.

The power stages, thanks to the large reserve of stored energy, provide enough power to drive every kind of load, in all conditions. The output current, capable of more than 15A, is limited only by fuses.

To avoid any home supply contamination, a power DC filter, equipped with surge limitation circuit, ensures hum-free condition for the toroidal transformers.

The elegant and sober case is typical of the Italian minimalist design, with a laser machining.
