SIA-025 Mk.II Integrated Amplifier

Possibly the most well reviewed high-end amplifier the industry has seen.

With the SIA-025 Mk.II, the Vitus Audio design team created a real integrated amplifier you’ll adore. The initial concept was a real challenge. Fitting all the parts the SIA-025 Mk.II shares with its larger siblings into a relatively small chassis. For example, the output stage is taken from the SM-10 monaural amplifier, by putting all efforts into developing this true balanced integrated class A amplifier, Vitus Audio succeeded in making a new standard in design and performance. Exactly what you would expect from the Signature Series.

The SIA-025 Mk.II adds great flexibility in terms of more inputs, the possibility of bi-amping should it be needed and a full bypass function for enabling compatibility with an external surround processor.

Partnering this amp with the Vitus Audio SCD-025 Mk.II CD Player forms a user-friendly and, dare we say, ‘cool-looking’ system that delivers an incredible performance.
