Musical Fidelity 550k supercharger power amplifier pair

Very unique and rare can work with your existing amp to increase output to 550w or just use as monoblocks 



The Supercharger 550K uses the latest in
low distortion circuitry in a bridged
configuration which delivers 550 watts rms.
The Supercharger 550K is designed to
increase the dynamic range of an existing
lower powered amplifier (from 50 watts to
200 watts) to 550 watts. The dynamic range
will increase by up to 10dB. This does not
necessarily mean that the average listening
level will be much louder; it’s just that
musical transients will now be delivered
without distortion or limiting. Overall the
listening experience is greatly improved
because of dramatically lower distortion
and increased dynamic range.
The 550K accepts both speaker level and
line level inputs. When driven from an
existing amplifier the sound quality is
greatly improved because the 550K presents
an easy load for the existing amplifier to
drive and at the same time gives up to 10dB
increase in dynamic range.
Alternatively, the Supercharger 550K can
be used as a conventional power amplifier
driven by a high quality preamp.
The Supercharger 550K is a perfect answer
to improve dynamic range in a single
beautifully engineered package. Used
properly and carefully, it should give many
years of outstanding musical reproduction.
