VITUS AUDIO SIA-025 MK2 Pure Class A Integrated Amplifier

When we undertook the design and construction of the SIA-025 Mk.II, we knew that the task would be a formidable one if we were to preserve or even exceed the quality for which we are famous.

At its core was combining fully integrated circuitry in the same chassis as our legacy product, the SS-010, with no sacrifice in terms of size or noise. The technologies that this required already existed but had to be refined and optimised for their new roles.

Despite the inherent challenges, our design team refused to compromise upon the renowned Vitus Audio principles including the rule that no component is required to deliver more than 25% of that which it is capable of handling. This dramatically increases component longevity.

The result of our design team’s efforts has been a technical and critical triumph – an amplifier with five inputs (balanced and unbalanced), a preamplifier output (for bi-amping purposes), balanced speaker outputs, and a full bypass function offering compatibility with external surround processors.

The balanced, fully integrated SIA-025 Mk.II performs to the standards our customers rightly expect from our Signature Series. It provides an aesthetically elegant system that delivers an incredible performance.
