Electrocompaniet EC5 Pre-amplifier
A decade of innovation unleashed
The ultimate expression of preamplifier purity has arrived.After ten years of painstaking development, Electrocompaniet unveils its revolutionary EC 5 preamplifier - a masterpiece that redefines signal integrity through groundbreaking proprietary technology while honouring the brand’s classic design aesthetic with meaningful new upgrades.At its heart lies Electrocompaniet’s game-changing volume control system: pure electronic construction with no mechanical components or relays to compromise your audio. This engineering marvel maintains a constant signal path length regardless of volume setting, delivering unprecedented transparency across 1000 steps with 0.1dB resolution.The fully discrete, dual-mono design operates in pure Class A throughout, powered by independent power supplies for each channel with multiple stages of noise and regulation. Two dedicated 80VA toroidal transformers and 15,000μF of storage capacitance per channel ensure uncompromised performance under any condition.With astonishing specifications including a 0.5Hz-450kHz frequency response and vanishingly low 0.0002% THD+N, the EC 5 represents the pinnacle of analog preamplification, where the electronics disappear, leaving only the music.The triumphant return of the volume wheel—now seamlessly integrated into the acrylic front panel—provides both tactile satisfaction and precise control. Behind the elegant 7-inch color display lies a component engineered to be the perfect command center for the acclaimed AW300M and AW800M power amplifiers.
