Rated at 600 millivolts , allowing it to pair effectively with a wide range of preamplifiers.
Utilizing MOSFET output devices, the FX series prioritizes thermal stability and high-bandwidth performance. Sound Quality and Performance musical fidelity fx power amplifier
The FX amplifier sits alongside other legendary Musical Fidelity products like the A1 Integrated and the high-power M6s PRX . While it may not have the extreme "Class A" heat of the A1, it offers a more practical power-to-heat ratio for users who need nearly 100 watts of clean power for larger rooms. Rated at 600 millivolts , allowing it to
The design often features a large bandwidth and discrete circuitry, though some DIY enthusiasts have noted that the power supply section is a prime candidate for modern upgrades to further lower the noise floor. Legacy and Context While it may not have the extreme "Class
For those looking to purchase or restore an FX unit, it remains a highly regarded piece of "British Hi-Fi" history that can still hold its own against modern mid-range amplifiers in terms of pure transparency and grip.
Like many Musical Fidelity products from its era, the FX amplifier is built with a focus on core audio performance rather than excessive aesthetic flourishes. However, long-term owners should be aware of a few maintenance considerations:
Some units may require updates to the thermal paste and insulators on the MOSFETs to prevent electrical conductivity issues that can arise over decades of use.
