kW750 Power Amplifier



Print This Page

Overview

The kW 750 is not like any amplifier from any other manufacturer. It is so powerful that it virtually never clips or limits. The basic sound is similar to single ended triodes. Because it never limits or overloads it always remains sweet sounding and relaxed. The kW 750 has massive unlimited dynamic range.

At first listen the kW 750 doesn't sound that remarkable your ear/brain interface automatically and instantly adapts to the huge unclipped headroom available; it's when you go back to an ordinary amplifier that the differences become so glaringly and painfully apparent. Ordinary amplifiers (and by that we mean below 200 wpc) are limiting and clipping regularly. When an amplifier limits in this manner distortion rises dramatically quite often giving rise to "an exciting" sound. What people are actually hearing is a great increase in distortion which adds harmonics to the signal. With the kW 750 this doesn't happen. It remains clean and stress-free under all conceivable circumstances.

If you want to hear the full dynamic range from a recording you need to have sufficient power to deliver that to the loudspeaker terminals. Apart from our kW 500 the kW 750 is about the only amplifier in the world capable of doing this. And it does it cleanly with a beautiful delicate exquisite sound. Our MD grabbed the first prototype and hasn't been back with it, it's that good.
