The SM-025 monaural amplifier builds on Vitus Audio’s legacy of musical authenticity, taking inspiration from the SIA-030 integrated amplifier while integrating new technologies. With a fully redesigned chassis and electronic circuitry, it delivers exceptional clarity, dynamic realism, and an emotionally engaging soundstage.
Key Features of the SM-025
- Dual monoblock design for channel separation and optimal isolation.
- 50Wrms Class A / 200Wrms Class AB (8 Ω) output
- 100 Wrms Class A / 400 Wrms Class AB (4 Ω) output
- New custom transformer with extremely low loss and 180,000 μF per channel capacitor bank.
- True balanced circuitry and zero global negative feedback for pure signal integrity.
- Enhanced chassis airflow and internal shielding for longevity and minimal interference.
- Selectable output modes (Rock & Classic) allowing listener customization without affecting signal integrity.
Improvements Over SM-011
- Overall performance improvements: higher resolution, expanded dynamics, and lower noise floor.
- Fully redesigned output stage with new, proprietary technology.
- New transformer designed for higher current and power capabilities.
- Increased Class A power from 25Wrms to 50Wrms (8 Ω) / 50 Wrms to 100 Wrms (4 Ω).
- Taller chassis (+42 mm) for improved cooling and integration of new technologies.
- Updated protection circuitry.
- USB firmware update capability.
