Quick Overview

VITUS AUDIO SM-103 Monoblock Amplifier

The SM-103 is a no-compromise design that will take on the very best, regardless of cost.A completely no-compromise design, this amplifier will take on the very finest products from around the world, regardless of their cost! With a completely no-compromise design, this amplifier takes on the very finest products from around the world, regardless of their cost! Based on the SS-103, each SM-103 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 truly balanced straight at the first input stage.

It is part of the Signature Series. The performance of these products redefines how close to the live event you can get by listening to reproduced music.

The difference between SM-102 and the new SM-103 in short:
1. Improved regulators based on MP-M201 design on input, which improves resolution, soundstage and presentation
2. Updated output stage to accommodate 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
