MUSICAL FIDELITY - 550K SUPERCHARGER (EA)

The New Supercharger from Musical Fidelity... Give Any Amp Virtually Unlimited Headroom Without Changing Its Sonic Character!

The new Musical Fidelity 550K Supercharger is a conceptual breakthrough that has never been done before in hi-fi. Installed between the existing amplifier and loudspeakers (nothing else has to be changed) it increases the power of your existing amplifier to more than 550 watts! This gives any existing system sufficient power to give realistic concert hall dynamics in your home. The 550K Supercharger uses the kW550 power amp circuit in a low gain configuration. All you have to do is disconnect speaker wire from the loudspeaker, connect that cable to the Supercharger’s input and then connect the Supercharger’s output to the loudspeaker and that’s it.

The circuitry is exactly the same as the award-winning Musical Fidelity kW550’s power amp circuit. In other words: ultra low distortion, superb sound quality, great linearity and superlative tonal performance. It will drive any loudspeaker with ease and deliver astonishing dynamics. Neutrality and linearity are givens here: whatever the sonic signature of your favorite amp is… now you’ll just get more of it… a whole lot more! The 550K Supercharger is housed in a modern sleek package with a small footprint and can easily be positioned next to or behind your existing loudspeaker. This new product from Musical Fidelity is revolutionary to say the least and you will not believe the improvement you’ll hear after you hear this cool new amplifier product! Our highest recommendation!

NOTE: Superchargers are sold as each, you'll need one for each speaker you intend to supercharge.

“Could the 550K increase dynamic range without destroying the essence of the amplifier’s sound? The answer was an unequivocal “Yes!” CDs sprang to life dynamically in every sense. Aside from the generous improvement in dynamics, there was no solid-state etch, dryness, nor was there any change in bass extension or punch. The 550K Supercharger was like a chameleon, adding power without making its presence known by any telltale sonic signature. Using a variety of very different sounding amplifiers of various power outputs overwhelmingly demonstrated to me that the 550 will retain the sonic attributes of your favorite amp, while increasing its output by 10dB or more. This is the sort of product that makes this hobby fun!”
