DutchNote Posted June 4, 2022 Posted June 4, 2022 (edited) Further information: Musical Fidelity Supercharger 550k is an amazing product. Have used them with great success using tube amplifiers and solid state to drive PMC twenty.26 and Infinity Rs1b. They turned my Luxman 507ux into an absolute powerhouse with so much more of everything the Luxman already does so well. Have original boxes so happy to ship at buyers expense.

Silver Audiophile Posted June 4, 2022 Posted June 4, 2022 I've owned many Musical Fidelity amps over the last 20 years, including these monoblock MF 550K superchargers. They are unique in that they can work as a regular monoblock power amps with line level input from a regular pre amp, or as a power amp 'booster' to another lesser powerful amp (like a tube amp, in the above example). In the later configuration, one keeps the sonic signature of the original power amp, which in itself makes this product pretty unique. My fond memories of this amazing amp is the power and control it had over the speakers drivers. Visceral tight bass, delicate full mids, and air out top. It's the same 550W monoblock amplifier circuit used in Musical Fidelity's kW550 integrated amplifier, but in a monoblock pair chassis. GLWTS 5
