Where Engineering Excellence Meets Musical Truth

Exceptional Clearance Opportunity: £18,995 

This Ex-Demonstration Vitus SIA-025 MK II represents a rare opportunity to acquire Signature Series performance at a substantial saving. Combining fully balanced Class A/AB topology with Vitus Audio's legendary build philosophy, this integrated amplifier delivers reference-grade sonics in an elegantly simple package – now available with £5,005 off the £24,000 RRP.

Engineering Without Compromise

The SIA-025 MK II embodies Vitus Audio's uncompromising approach to circuit design. At its heart lies the principle that no component ever operates beyond 25% of its capacity – dramatically extending longevity whilst maintaining pristine signal integrity. This fully balanced, dual-mono architecture combines 25 watts of pure Class A power with 150 watts Class AB per channel, ensuring effortless control across any loudspeaker load.

Born from the legendary SS-010 platform, Vitus's Norwegian engineering team refined every element to create an integrated amplifier that rivals separates. Five inputs (three balanced XLR, two unbalanced RCA), relay-controlled volume in precise 1dB steps, dedicated pre-out for bi-amping, and bypass functionality for home cinema integration – all housed within machined aluminium casework that epitomises Scandinavian precision.

The relay-controlled volume network ensures absolute channel matching, whilst the balanced topology delivers exceptional signal-to-noise ratios exceeding 100dB. This is amplification designed to reveal every nuance, from the delicate decay of acoustic instruments to the dynamic impact of full orchestral crescendos.
