SM – 025
SM-025 Signature Series
Boldly breaking away from the acclaimed SM-011 model, the SM-025 Class A/AB monophonic amplifier embodies Vitus Audio’s relentless pursuit of musical fidelity. Every aspect of its design has been meticulously refined to deliver greater power, higher resolution, expanded dynamics, and exceptional silence that brings out the subtlest musical nuances. Designed as separate monoblocks, this powerful amplifier brings out the finest details in your recordings with astonishing clarity and natural precision.
With an output power of approximately 100 watts in pure Class A and a dynamic boost to an impressive 400 watts at 4 ohms in Class AB, the SM-025
will certainly drive even the most demanding speakers.
At its heart is a specially designed 1.4 kVA UI transformer, characterized by exceptionally low losses (less than 2%), combined with a substantial capacitor bank with a capacity of 180,000 μF per channel. A fully balanced circuit from input to output and an uncompromising design with zero global negative feedback ensure uncompromising sound purity.
The SM-025 model incorporates advanced design solutions originally developed for the SIA-030 integrated amplifier. Its enclosure has been carefully engineered to enhance airflow efficiency, protect critical components, and significantly reduce interference. Every detail—from the improved internal shielding to the carefully engineered design—is intended to deliver a refined listening experience, free from interference and technical artifacts.
Hans-Ole Vitus’s visionary approach to design has once again resulted in a device that celebrates the inner emotional depth and vitality of music. Far from the pitfalls of sterile sound reproduction, the SM-025 reveals a vivid and holographic soundstage characterized by stunningly realistic dynamics.From intimate acoustic ensembles to expansive orchestral landscapes, the amplifier delivers an immersive listening experience, faithfully capturing the spirit and atmosphere of every recorded moment.
The SM-025 is not only a sophisticated feat of audio engineering, but also a profound statement of musical intent. For audiophiles who demand exceptional control, realistic dynamics, and an emotional connection to their favorite music, this amplifier embodies the art of perfect sound.
