The audio circuitry
At Linn because we strive for continuous improvement in everything we do we use appropriate
technologies to achieve our goals.There have been many fine amplifier designs over the history of audio.
Some use valves (tubes),some use bipolar transistors,some MOSFETs.Some manufacturers swear by Class A,
others by Class AB,one or two by Class D,and many others are somewhere in between.Two designs can use
the same components,but achieve completely different results.We believe,and have evidence to support,
that what you do with the parts and technology is always much more important than the name of the
technology.To illustrate this,our current power amplifier range contains MOSFET, monolithic,discrete and
bipolar designs.Our latest monolithic designs sound better than our previous discrete bipolar designs.Our
latest bipolar designs have more power and sound better than our earlier monolithic and bipolar designs.
So what did we choose for the Klimax Twin?
For several years we have been designing and building power amplifiers using monolithic (single chip)
power devices.These chips contain all the audio circuitry of a power amplifier in a few square millimetres of
silicon,and in principle are the ideal way to manufacture a power amplifier.
The high investment and technology required to design and manufacture these chips means that they are
targeted at high volume applications where audio performance is not the most important parameter.
However,we have worked closely with a chip manufacturer whose power amplifier chip designer is also a
keen audiophile.He has designed into a high volume chip tremendous capability,which can be realised by
careful attention to detail and the appropriate circuit topology.The power output stage of the chip uses
MOSFETs,and the high level of integration includes the complex linearisation circuitry required for low
distortion from a MOSFET based design.
