The SS-103 is a true Signature product that we are extremely proud to put our name on.


For those who want the very best in performance the SS103 is our statement stereo power amplifier in the Signature Series. With a completely no-compromise design, this amplifier will take on the very finest products from around the world, regardless of their cost!


The SS-103 houses brand new circuitry, which uses only the finest matched transistors and super precision resistors to ensure optimal working conditions for the different stages of each module. This combined with a special coupling of each input stage, results in an ultra linear frequency response.


The true balanced design, together with the local shunt regulated power supply, ensures excellent signal to noise ratio, making it possible to reveal every micro detail in the recordings. The result is a power amplifier, capable of exposing micro details/dynamics never heard before without compromising the coherence of the recording. As the design is true balanced, all non-balanced signals are converted to true balanced straight at the first input stage.


The performance of SS-103 redefines how close to the live event you can get by listening to reproduced music.


For those who want the very best, without going into our Masterpiece Series, there is no finer choice than the SS-103 or the SM-103.


Difference between SS-102 and the new SS-103 in short:


1. Improved regulators based on MP-M201 design on input, which improves resolution, soundstage and presentation


2. Updated output stage to accomadate sound modes.


3. Sound modes from MP-S201 implemented, giving the user the ability to select preferred presentation.


4. Updated top ventilation cover with VA logo


Upgrading from SS-102 to SS-103 is possible, but only at the Vitus Audio factory. Contact us for further information.
