Rega - Fono MM Mk5 - Phono Preamplifier Review unveils a phono stage that raises the bar for moving magnet amplification. By harnessing a fully discrete, cascaded complementary amplifier input stage and a two-stage RIAA equalisation circuit, the Fono MM Mk5 extracts unparalleled clarity, depth and musical authenticity from your favourite vinyl records.

At our hi-fi haven, The Audio Tailor, we’ve spent countless hours auditioning the Fono MM Mk5 across a range of turntables and cartridges. The results? A remarkably low noise floor, pristine transient response and a soundstage that feels alive from the first note.

Design and Build: Elegant Simplicity Meets Robust Construction

Encased in a newly redesigned aluminium chassis that seamlessly complements Rega’s Neo and Fono MC ranges, the Fono MM Mk5 is as much a visual statement as it is a technical powerhouse. The minimalist front panel and precision-machined casework underscore Rega’s ethos of function-led design, ensuring both aesthetic harmony and mechanical stability.

Key Technologies and Performance

The heart of the Fono MM Mk5 lies in its fully discrete, cascaded complementary amplifier input stage. This topology is optimised to squeeze every bit of resolution from your moving magnet cartridge, delivering a gain of 41.4 dB at 1 kHz with a remarkably flat frequency response from 15 Hz to 100 kHz. Rega’s two-stage RIAA equalisation splits the curve into separate amplification paths, minimising interaction and distortion while sharpening transient response.

Technical Highlights:

• Input Sensitivity: 1.7 mV for 200 mV output
• Gain: 41.4 dB at 1 kHz
• RIAA Accuracy: Better than ±0.2 dB from 100 Hz to 100 kHz
• Input Loading: 47 kΩ || 100 pF
• Frequency Response: 15 Hz (-3 dB) to 100 kHz (-0.2 dB)
