MONAURAL POWER
These incredible pure class A/AB mono amps share a chassis size with it’s sibling the SS-025 Mk.II. Based on the technical leaps made with the original SIA-025, the SM-011 uses SMD in place of leaded components wherever possible, fitting an incredible amount of technology in a modest space.
The completely modular Vitus Audio design means future upgradability is a given and in this version we introduced two different modes of coupling the output as developed for the MP-S201.
MUSICAL EXPERIENCE
The SM-011 builds on the success of the SIA-025. You get more of everything, more silence, higher resolution, more power and better dynamics. The amps feature a 1.4kVA custom UI transformer with <2% loss, a 240.000µF capacitor bank, is true balanced from input to output and as always, there is zero global negative feedback. This is a magnificent amplifier that will offer incredible performance for a lifetime.
FINISHING
The SM-011 comes in White, Jet Black or Warm Silver as standard. Titanium Orange, Dark Champagne and Titanium Grey are our most popular unique finishes.
