You own the Musical Fidelity FX-LPS phono preamp. You want a direct, signal-path-short chain: Turntable -> FX-LPS -> FX Power Amp -> Speakers. No tone controls, no digital conversion. Just pure analog gain.
So, how does the Musical Fidelity FX power amplifier compare to other amplifiers on the market? In terms of sound quality, it's right up there with the likes of the Krell K-300i and the Mark Levinson No. 585. However, its compact size and relatively affordable price point (around $6,000) make it an attractive option for those who want high-end sound quality without the hefty price tag.
A highly biased solid-state beast known as a "mostly Class A" amplifier. It provides roughly 50 Watts of pure Class A power before transitioning into Class AB to pump out a devastating 220 Watts per channel into demanding speaker loads.
Musical Fidelity has always maintained that an amplifier should be heard, not felt through harshness or artificial coloration. The FX series embodies this by focusing on ultra-low distortion, massive power reserves, and exceptional linearity.
The original FX-A1 is a stereo power amplifier rated at a conservative (35 into 4 ohms). Before you scoff at "only 20 watts," recall that Musical Fidelity’s legendary A1 integrated amplifier was also 20 watts. The FX-A1 is essentially a pure power amp version of that classic topology. It utilizes Class A/B operation running into heavy Class A bias for the first several watts—meaning for normal listening levels, it operates as a Class A amplifier, eliminating crossover distortion entirely. musical fidelity fx power amplifier
Musical Fidelity discontinued the FX series around 2018 to focus on their M-series (M2si, M3si, M6si) and the revival of the A1 integrated.
How does the FX stack up against modern rivals?
Unlike amplifiers that prioritize sterile bench-test measurements over real-world listening, Musical Fidelity tunes the FX series for emotional engagement. The goal is simple: to replicate the exact conditions of the recording studio or live concert hall directly in your listening room. Key Features and Engineering Excellence
It utilizes a discrete bipolar transistor output stage. By avoiding integrated circuits (ICs) in the critical audio path, Musical Fidelity achieved a lower noise floor and vastly superior transient response. You own the Musical Fidelity FX-LPS phono preamp
power amplifier remains a stellar example of vintage British engineering. For audiophiles looking to build a high-performance system on a budget, or those who appreciate the robust, industrial look of early 90s audio gear, the Go to product viewer dialog for this item.
When enthusiasts search for the , they are usually referring to one of three specific models, though the design philosophy is identical across the board.
While rated at 8 Ohms, the design, similar to other MF amps of the era (like the F15 or A1000), likely offers significant headroom for driving lower-impedance, less efficient speakers.
: Vintage units may require servicing of older capacitors to maintain original performance and longevity. Just pure analog gain
Because the FX series boasts high current output, it is an exceptional match for notoriously difficult-to-drive loudspeakers. Whether you own demanding electrostatic panels, power-hungry floorstanders, or low-sensitivity monitors, the FX amplifier will extract their absolute best performance.
: Original units may have electrically conductive thermal paste on the MOSFETs, which can lead to shorts or internal sparking if not replaced during servicing. Power Supply
Thanks to its high current capabilities, this amplifier pairs beautifully with notoriously difficult-to-drive speakers, including electrostatics, planar magnetics, and multi-driver floorstanders with complex crossover networks. Final Verdict: A Timeless Audiophile Investment
