Vitus Audio Signature SIA-030 Integrated Amplifier

The Vitus Audio Signature SIA-030 stands as a tour de force in modern high-fidelity engineering, seamlessly bridging the ethereal musicality of pure Class A amplification with the commanding grip of Class AB topology. Meticulously handcrafted in Denmark, this monolithic reference integrated amplifier defies the conventional limitations of single-chassis designs, utilizing an over-engineered 2.2 kVA double C-core transformer and a bespoke discrete resistor volume network to unlock an astonishingly holographic soundstage. It is a component born of purist philosophy and uncompromising physical execution, offering discerning audiophiles a masterclass in dynamic authority, tonal density, and absolute silence.

The Signature Series is where it all began for Vitus Audio. The products in this range represent perfectly our approach to audio component design – nothing left to chance, no cost spared.

Massive non-magnetic chassis designed to carry the weight of any required transformer or heatsink, a minimal, timeless aesthetic for which we are famed and and audio quality that is transformative, lifelike and breathtaking.

In a word – foundational

The Signature Series is the foundation upon which everything else has been built.

The key development achievements that make the Signature Series what it is include;

• A custom designed UI transformer (which took around 4 years to perfect) featuring a low open to closed loop voltage drop giving excellent control and fantastic performance in the lower frequencies and an overall quietness, especially for their size.
• Full discrete gain modules based on zero global feedback, non-intrusive DC servos that add no colour to the sound and very high bandwidth (in the MHz)
• A complete modular design allowing for future upgradability.
• A relay-based shunt volume control which today has a resolution of 0.5-1dB per step. (product dependant)
• An over-engineered power supply with special configuration regulators for all low power consumption elements.
• Complex circuitry where every improvement offers a noticeable change in output.

What has been achieved by our engineers is nothing short of astonishing. Every element of this amplifier has been obsessed over and refined to the point of perfection creating the component we present here. A powerhouse of an amplifier in a neat, handsome chassis with optional DAC and phono stage. A truly integrated amplifier for the discerning audiophile looking to preserve space in their listening environment.

Redefining the standard

Creating a component improving upon the much admired SIA-025 was never going to be an easy task. The goal was to design an integrated amplifier that offered that more power and more options, an amp that remained modular, that offered the same elegant looks and the compact chassis of its siblings in the Signature Series.

Serious technology

While this amplifier sits midway in our range, it’s no lightweight when it comes to performance offering 200 W per channel in Class AB mode into 8Ω and double that at 4Ω. And with a frequency response up to 800kHz the amp showcases incredible bandwidth.

We leave you with some quotes from Peter Breuninger of AV Showrooms to whet your appetite;
“The backgrounds are so black that you hear so much detail in a non-fatiguing way… This is one of the best solid state amplifiers I’ve heard in my 33 year reviewing career… Seek this amp out, it will blow your socks off!”

Finishing

The SIA-030 comes in Pure White, Jet Black or Warm Silver as standard. Titanium Orange, Dark Champagne and Titanium Grey are our most popular unique finishes.

Mode selection – Classic & Rock mode

The SIA-030 integrated amplifier features “Classic” and “Rock” modes, which subtly modify the amplifier’s sound output. The “Classic” mode is designed to enrich the listening experience, offering a richer, more relaxed, and detailed sound. In contrast, the “Rock” mode amplifies the robustness and dynamics of the music, appealing to those who prefer a more forceful and impactful sound. These adjustments are achieved through a complete reconfiguration of the output stage, without the use of any filtering or alterations to the signal path, thereby preserving the purity and integrity of the audio signal. Choosing between these modes depends solely on personal preference, as there is no objectively right or wrong setting; it entirely depends on what suits your listening tastes and/or mood.

Class selection – Class A and Class AB

The SIA-030 integrated amplifier offers enhanced personalization through selectable Class A and Class AB operation modes. Class A mode is well known for its rich sound quality, providing greater clarity and detail, perfect for nuanced audio experiences. Conversely, Class AB mode maintains quality sound while offering greater power efficiency and sometimes a more dynamic performance. These operational classes can be used in combination with the the “Classic” and “Rock” mode settings, allowing further customization of the audio output based on individual preferences, ensuring a tailored listening experience.

Modular build – Phonostage & DAC/Streaming modules

The SIA-030 integrated amplifier features a modular design that allows for the addition of optional DAC/Streamer and phono stage modules. This design makes it adaptable for different audio setups and future upgrades of technology.

Masterpiece technology in a signature product

The SIA-030 integrated amplifier incorporates state-of-the-art technology from the brand’s top-tier Masterpiece series. Despite its’ size, squeezed into a compact design is a fully regulated power supply that enhances the entire system, by ensuring exceptionally stable, fast, and clean power delivery not only to the lower power circuitries like the preamplification stage but also to the amplifier’s output stages and hence to the speakers. Guaranteeing a full listening experience across all bandwidths.

This rigorous approach to power management combined with our discrete designs preserves the integrity and purity of the audio signal, significantly reducing distortion and enhancing clarity, detail, and overall musical sound quality by additionally lowering the noise floor to exceptionally low levels.

The Vitus Audio SIA-030 stands supreme in the realm of high-end integrated amplifiers, and our continuous pursuit of innovation has helped establish this new standard for audio fidelity and system integrity in the industry.

Effortless software updateability

The Vitus Audio SIA-030 offers effortless software updateability by simply downloading a .bin file, placing it on an empty USB drive, and inserting it into the unit’s service port—ensuring your amplifier stays up-to-date with minimal effort.
