AVID Sigsum Integrated Amplifier (with Built-In Pulsus Phono Stage)
The AVID Sigsum Integrated Amplifier is a complete high-end solution designed to deliver exceptional performance from ‘needle to ear’. Built using AVID’s cascading design philosophy, it combines reference-level technologies into a single, uncompromising component that prioritises musicality, control, and realism.
Developed with a focus on perfecting every stage of the amplification process, the Sigsum integrates four critical elements—power supply, preamplifier topology, power amplifier, and volume control—each engineered to the highest standard. The result is a cohesive and highly capable amplifier that delivers both power and finesse in equal measure.
With a massive power supply, reference-derived amplification, and a world-class volume control, the Sigsum offers effortless dynamics, deep bass control, and an incredibly natural presentation. It is designed to drive a wide range of loudspeakers with ease while preserving the integrity and emotion of the music.
