Creating a product intended to be a model up from a much-coveted and multi-award-winning icon (in this instance, the SIA-025) is no easy task. A casual exploration of the sheer number of 5-star reviews and awards from all over the world tells you all you need to know about the SIA-025 Mk.II. It has become a glittering halo in the world of integrated amplifiers, so the SIA-030 always had it’s work cut out.
This stratospheric performance expectation, combined with the goal of keeping the chassis as small as possible, made the design phase extremely challenging, pushing the Vitus Audio team to the absolute limit. Thinking way outside of the box and endlessly obsessing over every possible micro-detail of the design was required to achieve the almost impossible.

The technology inside the SIA-030 reuses the regulated power supply from the output stage of the Masterpiece MP-M201, combined with new technology for the lower voltage stages.
The regulator module can easily be upgraded, likewise for the gain-stages in both the preamplifier and power-amplifier section. The newly developed volume control is now regulated only 0.5dB per step throughout the entire volume control. The total gain available is 18dB, which combined with the input sensitivity selector and high resolution of the volume control, offers full versatility for any sources and loads.
Two optional modules are offered. Firstly, a full DAC/Streamer module already known from the Rl- 101 / RD-101 but further optimized and enhanced for a performance befitting the SIA-030.
Secondly, available soon will be a full phono stage option with mm/mc support and individual load and gain settings.
Fully equipped, the SIA-030 will be all you need for a minimalistic ‘uber’ performing system.
