Musical Fidelity KW550 Integrated Amplifier

Here we have a heavyweight, in every sense of the word, integrated amplifier from British company Musical Fidelity. It actually comes in two large units – one being the main amplifier and the other the power supply. It dates from 2007, is in good fully working condition, and is supplied in original factory packaging along with mains cables plus our usual three month warranty.
Musical Fidelity Say….
The KW550 is a perfect answer to most integrated requirements in a single, beautifully engineered package.
Great attention has been paid to internal layout, isolating each circuit section to prevent possible interaction. The preamplifier sections are our finely tuned and tweaked tube input line level tube preamplifier which uses 6SL7s for smooth sound coupled with low noise and virtually no distortion. This also includes our top quality low noise phono stage which caters for both MM and MC cartridge users. The power amplifier consists of two mono block amplifier modules with completely separate supplies for the absolute best in separation and imaging. Rated for 550W nominal they are enough to drive even the most demanding loudspeakers with ease. Low distortion and very quiet they will deliver all music types exactly as the artist originally intended.
The resultant performance achieved by this unit is among the best in the world. It has excellent signal to noise ratio, low distortion, wide bandwidth, huge dynamic range, extraordinary resolution, and fine detail.
