Kudos Sigao – the sound of silence

Launched at the Munich High End Show in May 2024, the Kudos Sigao Drive is an unpowered crossover that sits between your pre and power amplifiers to improve the performance of your Kudos loudspeakers, no matter what amplifiers you use.

There is no loudspeaker drive unit available that can reproduce the entire spectrum of frequencies that the human ear can hear (20 – 20,000 hertz) which is why hi-fi speakers have woofers for the low notes and tweeters for the highs. Conventionally the audio signal is split inside the loudspeaker with a passive crossover circuit, which means that your amplifier has less control over the loudspeaker drive unit because of the components in the crossover.

To combat this, active crossovers split the signal before the power amplifiers, which means that you have one power amplifier for each loudspeaker drive unit, and the power amp is connected directly with nothing between it and the loudspeaker drive unit.

However this solution introduces problems of its own. The active crossover needs to be designed for each amplifier and speaker combination, and more importantly, it needs to be powered, which can introduce noise into the audio signal.

The name Sigao is from the ancient Greek word for maintaining silence. This is appropriate because Sigao Drive does not need a power supply, so it does not add any noise. It silently splits the signal so that each power amplifier has direct control of the drive unit, and only needs to amplify signals in the frequency range for that drive unit, giving you a cleaner, clearer, more focussed sound.

On the back of the Sigao Drive is a set of RCA input connectors to connect to your preamplifier output, and three sets of outputs to connect to your power amplifiers. With the exception of the Titan 808, the Kudos range only needs two of these to be connected.

There are also five “plugs” which enable Sigao Drive to be perfectly matched to your system. Three of these are to provide the optimum loading for the power amps, one determines the crossover frequency (the frequency at which the tweeter takes over from the woofer) and finally the treble gain, which allows you to tailor the sound depending on whether you prefer smoothness or detail. If you change your amps or speakers at any point, we can provide you with a new set of matching plugs so that Sigao Drive will continue to help your system perform at its best for many years to come.

Production units should be available for demonstration and delivery from July 2024 – please get in touch if you would like to hear Sigao Drive for yourself.

Organik DAC Promotion for Akubarik owners

If you are lucky enough to own a pair of Linn’s fabulous Akubarik floorstanding loudspeakers, then you are now able to upgrade to Organik, Linn’s best ever DAC.

Introduced three years ago in the Klimax DSM, Organik is the first DAC to be completely designed and manufactured in-house by Linn. Improving on the already excellent Katalyst, Organik uses advanced circuit design to deliver an analogue signal with lower noise and distortion than has been possible previously.

For owners of the Akubarik Exakt loudspeakers, we will need to visit your home to remove the amplifier modules from your speakers and return them to Linn to be upgraded. Once complete we will then refit the upgraded modules for you to enjoy. Cost of this service is £7000.

If you have Aktiv Akubarik speakers then for a limited time you can trade in your amplifier modules for brand new Exakt Organik modules. This costs £11000 per pair including fitting and allows you to enjoy the benefits of Exakt and Organik in one upgrade.

Linn Klimax Solo 800

Today Linn has launched their most powerful amplifier ever – the Klimax Solo 800 Monoblock.

As its name suggests, it has a power output of 800 watts into a 4 ohm load. However, as the saying goes, power is nothing without control. Klimax Solo 800 ensures any speaker, no matter how difficult the load, can perform to its full potential. At normal listening levels, Klimax Solo 800 has a Total Harmonic Distortion + Noise ratio that is around a hundred times better than other similarly priced amplifiers.

Innovations in the design of the Solo 800 which enable this leap in performance include:

  • A new, high power version of the Utopik Switch Mode Power Supply that has transformed the performance of Linn source components recently. In Klimax Solo 800, the Utopik can provide up to 2,000 watts of stable power to drive the amplifier, regardless of mains voltage and quality.
  • Adaptive Bias Control to minimise transistor crossover distortion. In common with most high powered, high fidelity amplifiers today, the Solo 800 is a Class AB design, which uses multiple output transistors (16 in this case). For a Class AB amplifier to sound its best and have a long lifespan, there is a bias current that needs to be adjusted to an optimal level. This is normally only done when an amplifier is built or serviced and tends to drift over time. Adaptive Bias Control allows Klimax Solo 800 to continually adjust its own bias current to each of the 16 transistors which keeps crossover distortion to an absolute minimum, no matter what the age or temperature of the internal components.
  • Well designed, cool running circuits and thermodynamically efficient casework mean that Klimax Solo does not need the cooling fan that competitor products depend upon.

Power up with Utopik

Launched in the Selekt Edition Hub last year, the Utopik is Linn’s best ever Switch Mode Power Supply (SMPS). It provides clean, stable and isolated power for your Linn equipment regardless of your mains voltage or quality, whilst being incredibly energy efficient compared to conventional power supplies.

Whilst the superior efficiency of switch mode supplies has long been acknowledged, along with their smaller size and weight, they are rarely used in hi-fi equipment due to difficulties in keeping electrical noise levels low. Linn’s expertise and 30 years of experience in SMPS manufacture has overcome these difficulties and the power supplies easily outperform their heavy and inefficient conventional competitors. New features in Utopik include:

Power Factor Correction: Normally Switch Mode Power Supplies draw current from the mains in a series of short pulses. This introduces noise into the supply which can affect other equipment on the same circuit. Utopik’s design draws current evenly across the AC Mains waveform, in proportion to the incoming voltage, which can be anything from 90V to 250V.

Precision Regulated Voltage Rails: Each voltage rail within Utopik is precision controlled, with a feedback loop keeping the voltage level stable regardless of the current demands on the power supply.

Intelligent Valley Switching: Usually a SMPS switches in and out at random points within the AC Waveform. This can introduce randomised noise into the power supply. With Intelligent Valley Switching, Utopik switches as close as possible to the zero voltage point on the AC wave, minimising the noise.

Utopik is fitted as standard to all Klimax, Selekt and Kustom DSMs from 1 November 2023, and can be retro-fitted to any of the following products regardless of age:

  • Klimax DSM (All Models)
  • Klimax DS (All Models)
  • Klimax System Hub (All Models)
  • Selekt DSM (All Models)
  • Akurate DSM (All Models)
  • Akurate DS (All Models)
  • Akurate Exaktbox-6 and -10
  • Kustom DSM Z4 and Z8
  • Majik DS (All Models)

With the exception of the Kustom DSM we can carry out the upgrade at your home in less than an hour so there is no need send your equipment back to Linn.

Price for the upgrade is £1350 including fitting and VAT.  However if you buy any qualifying Linn product (which includes the Majik 109 loudspeakers at £1500) before 31 January 2024 you can receive a free Utopik upgrade for a product you already own. In many cases we can also provide a free Utopik upgrade if you spend £3000 on other upgrades (e.g. turntable parts or DACs).

LP12-50, LoveFrom Linn

This year it is the fiftieth anniversary of the Linn LP12 – a product that revolutionised the way that hi-fi was demonstrated and sold by challenging the conventional wisdom that loudspeakers were the most important part of the hi-fi chain, and encouraging customers to trust their ears when making buying decisions.

The LP12 is still in production today, it’s modular design allowing even a fifty year old turntable to be upgraded, piece by piece, to the latest specification.

To celebrate this landmark anniversary Linn has teamed up with LoveFrom – a design agency run by Sir Jony Ives, formerly lead designer of many iconic Apple products.

The LP12-50 features the new Bedrok™ plinth, formed from layers of beech compressed under extreme pressure to create a solid and heavy plinth with minimal resonances to isolate the turntable mechanics.

LP12-50 also has Sir Jony’s trademark rounded corners, a new machined control button, and – refining the one part of the LP12 that really needed refining – new lid hinges, crafted in Scotland.

There will be just 250 of these turntables produced, at £50,000 each. To register your interest please visit https://www.linn.co.uk/uk/turntables/lp12-50
