Musical Fidelity 550K Supercharger review


If you're seeking fireworks, light the blue touch paper, and retreat a safe distance – the MF 550K Supercharger won't disappoint

Huge gains in authority, controls and dynamism positively revel in high volumes

Not without a specific sonic character ; lacks a little resolution

Bend your speakers to your iron will by treating them to an abundance of power: if a £3000 amplifier upgrade appeals, hear these

Musical Fidelity 550K Supercharger


Supercharger. It's a word that has an undoubtedly romantic ring, reminiscent of the Hon. Henry Birkin and his Bentley Boys, sweeping their way to four successive Le Mans victories in the 1920s

Offers good sound, and superior dynamic range and headroom across a range of material, Comes with versatile line- or speaker-level inputs

Supercharger concept works well with valve amps, but sounds best when used just as power amp, fed from pre-amp, Could be crisper and tauter

This exceptionally powerful and unusually versatile power amp delivers good sound, ultra-wide dynamic range and offers lots of headroom for peaks. The Supercharger concept is particularly well suited for use with high-quality, low-power (valve) amps.

What the hell is a Supercharger? More importantly what the hell does it do? Perhaps even more importantly: ‘Do you need one?’
