Marantz Ma-9s2 User manual

MA-9S2 Reference Monoblock Amplier

We began with the historic Model 9. We improved that distinctive voice with the MA-9S1. And

now we present the MA-9S2 as the latest step in our relentless pursuit of sonic accuracy. It defines

new horizons in both musical performance and contemporary elegance.

When you first see the MA-9S2, you’ll be impressed with its clean yet purposeful look. When you listen,

you will realize that the one thing that surpasses the MA-9S2’s construction, is it’s sound.

Far more than massive current capability elegantly housed in brushed aluminum, the MA-9S2 thoroughly updates the performance of

our original Model 9. It’s the culmination of more than a half-century’s eort in reproducing audio in the home. Of course, this must be

a Marantz. A major untertaking, the engineers at Marantz tore apart the MA-9S1 and redesigned it from the ground up to be even faster,

with less noise, and more authority. The MA-9S2 represents over 50 years of expertise in amplier circuitry, and sincere love of music.
