Linn Klimax Twin Power Amplifier

The Klimax Twin is Linn's reference power amplifier. It is the product at the top of the range — the amplifier against which everything else in the Linn lineup is measured — and it is built without compromise in power supply, output stage design, or materials. In a Linn Exakt active system, the Klimax Twin represents the furthest point you can take amplifier performance within the Linn ecosystem.

It is a two-channel design, operating in stereo or — configured as a mono block — driving a single channel with the full resources of the chassis behind it. In mono block configuration, paired Klimax Twins are among the most capable amplifiers available for Exakt active use, providing each drive unit with a dedicated, reference-grade amplification stage of extraordinary dynamic authority and resolution.

The Klimax Twin receives its signal from a Klimax DSM over the LINN link digital connection. All signal processing — crossover filtering, time alignment, speaker-specific optimisation via Linn Space Optimisation — happens in the DSM. The Twin's function is to convert that processed digital signal into the mechanical movement of a drive unit with the minimum possible degradation between input and output.

The Klimax Design Philosophy

Linn has been building power amplifiers for decades, and the Klimax Twin represents the accumulated understanding of what matters at the limit of performance. The power supply is not a shared compromise between two channels — it is a fully specified, high-current design built to handle the worst-case dynamic demands of any programme material without constraint. The output stage is built with components selected for linearity and consistency, not cost, and the chassis design prioritises mechanical stability and thermal management.

In an Exakt active system, the amplifier is directly connected to the drive unit. There is no crossover component between the Klimax Twin and the driver cone. The quality of what comes out of the amplifier is the quality of what moves the driver. At this level, the differences between the Klimax Twin and lower-tier amplifiers are not subtle.

The sonic character of the Klimax Twin — to the extent it has one — is the absence of character. It does not add warmth, or air, or any of the colourations that are sometimes described approvingly in amplifier reviews. It amplifies the signal Linn's DSM sends it, faithfully and with complete authority. The result, in a well-configured Exakt active system, is music that sounds like music: detailed without being clinical, dynamic without compression, spacious without artificiality.

Klimax Twin in an Exakt Active System

In stereo configuration, the Klimax Twin drives both channels of a two-way active speaker — bass to one channel, treble to the other — or both channels of a passive speaker pair. In a three-way active stereo system, multiple Klimax Twins are needed to cover all six required channels.

The Linn 530 is a self-contained Exakt active loudspeaker with its own integrated amplification, so it does not require a separate Klimax Twin. For those building active systems around other Linn-compatible loudspeakers, the Klimax Twin is the amplification reference.

For system configurations that need more than two channels, the Klimax Twin's mono block capability — one chassis, one channel — allows each drive unit in a multi-way active system to have its own reference-grade amplifier. It is an extraordinarily capable and extraordinarily expensive way to build a loudspeaker system, and in our experience the results justify it.

Who Is It For?

The Klimax Twin is for those building the finest Linn Exakt active system available, without compromise. It requires a Klimax DSM to drive it properly and is most often found in systems built around high-quality multi-way loudspeakers where the full dynamic and resolution capability of the amplifier can be put to use. It is not an entry point — it is the destination.

Buying from Martin's Hi-Fi

Martin's Hi-Fi has been in Norwich since 1968, and the Linn range has been part of what we do for years. We are still family-run — Ted Martin's daughter Elizabeth runs the business today — and we stock only brands we have heard properly and stand behind.

A Klimax Twin system is a major investment, and one that deserves proper guidance from a dealer with long, first-hand experience of the Linn range at its best — which is exactly what we offer.
