Brama Preamplifier


Description ▴

The heart and soul of your system.

Brama Preamplifier’s linestage is Vinnie Rossi’s realization of the audiophile dream – having it both ways, each at the highest possible level of performance:
Whether you are seeking the tonally rich and holographic presentation of 300B directly-heated triodes, or the absolute purity of solid-state, the Brama Preamplifier is the only one in the world that lets you enjoy both sonic presentations with the press of a button.

Fully balanced, dual mono input-to-output architecture is positioned directly behind the rear panel for the shortest possible signal paths. Super-regulated power supplies for both the power rails and 300B heating supply achieve ultra-low noise and optimal transient response
