Vitus SM-103 MK2

The SM-100 was the very first power amplifier to come out of the Vitus Audio design studio. A true balanced amplifier that changed the marketplace and made clear what a monaural power amplifier should provide to the user. The initial design was housed in two chassis but we always intended to create a four chassis system to separate power circuitry from audio circuitry.

The development of the MP-M201 saw this dream become a reality and we took the development leaps forward made with that amp and the amazing advancements made in the SS-103 into the SM-103 creating a powerhouse that will astonish with micro detail and resolution.

With a completely no-compromise design, the SM-103 Mk.II can take on the very finest products from around the world, regardless of their cost. Based on the SS-103, each SM-103 Mk.II uses only the finest matched transistors and super precision resistors to ensure optimal working conditions for the different stages of each module.

This amplifier redefines how close you can get to a live performance experience from your recordings. With future upgradability a given thanks to their internal modular design, this is an amplifier that will bring joy for many decades to come.
