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?

The Klimax audio design was developed from our previous best amplifier, the

Klout, which uses completely different circuitry from any of our other

amplifiers. Like the Klout, the Klimax also uses all surface mount technology

with eight, rather than two ultralinear bipolar output power transistors. There

are many other refinements and advances over the Klout design, the result

of many years of experience, analysis, experimentation and our simple,

consistent method of judging sound quality. We use bipolar output

transistors in this design because they are the most appropriate solution.
