About the SIA-025 Mk.II
The Vitus Audio SIA-025 Mk.II is a high-end, fully balanced solid-state integrated stereo amplifier from Vitus Audio’s Signature Series. It combines a relay-controlled passive resistor-network volume control with switchable Class A and Class AB operation: approximately 25 W per channel in Class A and 150 W per channel in Class AB into 8 ohms. It provides three balanced XLR and two single-ended RCA analog inputs, an XLR preamplifier output for bi-amping or connection to an external power amplifier, balanced speaker outputs, and a full-bypass function for integration with an external surround processor. The amplifier is designed and manufactured in Denmark. Published specifications vary slightly between production documentation and older dealer literature, particularly for dimensions, weight, volume range, and power figures; the figures below prioritize Vitus Audio’s current published data.
