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.
