Vitus SIA-030 Integrated Amplifier
The SIA-030 sits at the summit of Vitus Audio's Signature Series — an integrated amplifier that draws directly on the engineering of the company's flagship Masterpiece range and makes no concession to compromise in either design or execution. It is a serious instrument for a serious listener, and it answers the question of how good an integrated amplifier can genuinely be.
Fully Regulated Power Supply
The SIA-030's power supply is fully regulated throughout — delivering exceptionally stable, fast, and clean power to every stage of the circuit, from preamplification through to the output stages. The practical result is a noise floor low enough that low-level musical information — the kind that gives a recording its sense of space and breath — is retrieved rather than buried.
Classic and Rock Modes
The SIA-030 offers two selectable sound modes — Classic and Rock — that completely reconfigure the output stage without filtering or alteration to the signal path. Classic offers a richer, more relaxed presentation with finer detail resolution. Rock amplifies dynamics and impact for a more forceful, immediate sound. It is a meaningful choice, not a cosmetic one.
Class A / Class AB Operation
The SIA-030 can be switched between Class A and Class AB operation. Class A mode prioritises richness and clarity; Class AB unlocks the amplifier's full power output — figures are set out in the specification table below. The ability to move between these two fundamentally different modes of operation within a single chassis is one of the SIA-030's most compelling engineering achievements.
Modular Design and Updateability
The SIA-030 is built on a modular architecture. An optional DAC/Streamer module and an optional phono stage can be added to the unit, allowing the amplifier to grow with a system without requiring a separate component for each function. Firmware updates are handled via a .bin file loaded onto a USB drive and inserted into the unit's service port — keeping the SIA-030 current as Vitus Audio develop new capabilities.
Masterpiece-Series Technology
The SIA-030 incorporates state-of-the-art technology derived directly from Vitus Audio's top-tier Masterpiece series. This is not a filtered-down interpretation — it is the application of reference-level engineering within the Signature Series framework.
