Musical - Fidelity Fx Power Amplifier
Musical Fidelity FX power amplifier is a high-performance audio component within the brand's legendary "F-Series" lineup, recognized for delivering a "muscular" and natural sound profile. First making waves in the early 1990s, the FX and its siblings—such as the 100-watt Class A F15 and the 220-watt F18—were designed to handle demanding speaker loads with ease, characterized by their massive bandwidth and neutral yet warm sonic signature.
