AMS100 (DISCONTINUED) - Overview

We are confident that the AMS100 is the most advanced pure Class A power amp ever made. It clearly tops the trio of exceptional power amplifiers within our AMS range.

The 100 Watts per channel AMS100 features the same core Class A excellence as its AMS35p and AMS50 siblings, boosted significantly by further trickle-down technology from our flagship TITAN amp, plus a unique power supply design.

Its innovative PSU arrangement – a first in the hi-fi world – gives the AMS100 huge technical advantages over any other amp, by negating power-supply noise.

The result is the most clean, powerful performance we’ve produced: if you’re a true musical purist, this is the amp for you.

The AMS100 is the perfect partner for our Primo pre-amp, sharing the same state-of-the-art engineering and premium aesthetics.

Stereophile’s review said: “Musical Fidelity's AMS100 is magnificent,” while Hi-Fi News proclaimed it “maybe the ultimate Class A transistor amplifier”.
