The only connected speaker that delivers high fidelity sound in such a compact design

Up to 900W from a 3 litre speaker, starting at £990

Devialet today unveils Phantom REACTOR, a new pinnacle in

sound engineering, and the next step in the company’s vision to make the emotional

power of sound accessible to as many people as possible through ground-breaking


Phantom REACTOR is an ultra-compact speaker that delivers unprecedented power, fidelity

and volume. The result of three years of research and development in acoustic and mechanical

engineering, Devialet is proud to announce Phantom REACTOR 600 and Phantom REACTOR

900, as the latest additions to the Devialet Phantom family.


With Phantom REACTOR, Devialet has once again taken sound to a new level. It is the only

ultra-compact loudspeaker with a maximum volume of 98 dB SPL, enabled by an

unprecedented 900W of peak power. Phantom REACTOR reproduces sound as the artist

intended: all the details with zero distortion, zero saturation or background noise. Just pure

sound reproduction.

Phantom REACTOR is precision-engineered, both technically and physically, for optimal audio

performance. A compact spherical design with perfect acoustic form, two push-push woofers

with extreme cone excursion delivering ultra-deep audio and one full-range speaker combine for

the ultimate sound experience in a smaller package, with zero compromise on sound quality.

• 219mm (Length) x 157 mm (Width) x 168 mm (Height), it is small enough to be held in one

hand, but can play as loudly as a symphony orchestra playing at full force

• Delivering unreasonable sound from infra-bass at 18Hz (like having a subwoofer in the room)

to sharp treble at 21Khz

• Phenomenal sound amplitude without distortion, saturation or background noise through

unique Devialet-created technology

Phantom REACTOR is plug and play. It can be operated wirelessly via Bluetooth, Spotify

Connect, Airplay, UPnP or through an analog or optical jack connection - and can be remotely

controlled through a dedicated app.


Since it was first founded, Devialet has worked continually to miniaturise its inventions and

make them available to new audiences.

The miniaturisation of Phantom REACTOR should be a technical impossibility – but it has been

made possible by the unrelenting passion of 100 Devialet engineers, constantly challenging

audio conventions, one radical invention at a time. 11 additional patents have contributed to

Phantom REACTOR’s amazingly disruptive design, all leading to an ultra-compact form at a

more accessible price.

Breakthrough Devialet innovations, pushed further and embedded in Phantom REACTOR


● Analog Digital Hybrid (ADH.), Devialet's core innovation in sound amplification,

combining the sophistication of Class A analog amplification with the power and

compactness of Class D digital technology;

● Speaker Active Matching (SAM.), the mathematical model that ensures perfect control

of speakers and high acoustic fidelity of Phantom REACTOR;

● Heart Bass Implosion (HBI.), the revolutionary acoustic process that emits bass sounds

with phenomenal depth and physical impact;

● Active Cospherical Engine (ACE™), the spherical design and the perfect acoustic form

to reproduce a sound and diffuse its energy linearly in all directions.


Phantom REACTOR is designed, manufactured and assembled in France, in a new

manufacturing facility opened by Devialet specifically for Phantom REACTOR.

For Phantom REACTOR, Devialet is expanding its distribution network. In the UK, Phantom

REACTOR will be available at Selfridges, Harrods,, as well as

through Devialet’s own stores and network of high-end audio resellers including Hidden Systems Windsor.

Changes to LINN Exakt Box Model Range

Changes to LINN Exakt Box Model Range

Changes to Exakt Box Model Range

Exakt is Linn’s proprietary digital active crossover technology that ensures perfect time alignment of every note and every harmonic, making the music sound less like hi-fi and more like real music.

You can either buy a complete Linn Exakt system or by purchasing one or more Exakt boxes you can upgrade your existing system to Exakt technology.

The Majik Exaktbox-I combines an eight channel Exakt crossover with eight 100 watt power amplifiers. This product is being discontinued at the end of this year, so if you would like to upgrade your Majik system using a visually matching Exakt box then you will need to get your order in soon.

The new Akurate Exaktbox-I is now available that also offers eight channels of 100 watt Exakt amplification. Next Spring the Katalyst architecture will be added to the Exaktbox, improving things even further.  This will be retrofittable to existing Akurate Exaktbox-I units at the cost of the difference in retail price between the old and new units.

Majik Exaktbox-I will also be upgradable to Katalyst, but this will be charged at the full upgrade price.

To learn more about Linn’s Exaktbox range, or to hear the difference it makes in your own system, please get in touch.

New Linn Selekt DSM

New Linn Selekt DSM

New Linn Selekt DSM

The big Linn launch of 2018 has to be the Selekt DSM.  Precision engineered to be a “tactile, interactive” product, Linn claims that the DSM will bring life back into digital music.

Apart from the shape, the most obvious physical difference between this and the other Linn DSM products is the inclusion of a rotary dial on the top of the machine.  This allows adjustment of the volume and enables the user to scroll through and select from playlists.  There are also six silver buttons on the top of the unit that can be configured (or “pinned”) for various functions.

As is usual for Linn, the Selekt is designed for life, and therefore designed to be upgradeable.  Harking back to the days of the original Wakonda and Majik amplifiers, the Selekt can be retro-fitted with “cartridges” to improve performance and functionality as the technology becomes available.  Available upgrades in the new year are rumoured to include 5.1 surround amplification, a headphone amplifier and wireless and Bluetooth capability.

Comparisons are obviously being drawn with the Naim Uniti Nova and our current best seller in this segment, the Devialet Expert Pro 140.  All are great products and your ears will guide you as to which one is the best for you.

Prices for the new Linn Selekt DSM are as follows:

Selekt DSM £4,000
Selekt DSM with integrated power amp £5,250
Selekt DSM with Katalyst £5,500
Selekt DSM with integrated power amp and Katalyst £6,750

New LINN Akurate Katalyst

New LINN Akurate Katalyst


Linn's new Katalyst DAC Architecture performs digital-to-analogue conversion with greater precision than ever.

By using independent power supplies, a super-accurate master clock, an ultra-low distortion output driver and a high stability input reference level, it gives the most accurate conversion of digital data to an analogue signal currently available.

So what does this new technology sound like? The most common reaction from the clients who have already upgraded is "wow".  Katalyst makes the music more like music and less like Hi-Fi. It gives a closer insight into how the artist wanted their music to sound.

Simply put, this new technology allows music to further enrich your life.

The best way to find out about Katalyst is to come and hear it for yourself.

Review of Lejonklou Sagatun Mono and Tundra Mono by HiFi+ July 2017

Here's a great review of Lejonklou Dual Pre Amp and Dual Mono amplifier by Alan Sircom

"To my mind, the Lejonklou Sagatun and Tundra Mono amps are how amplifiers are supposed to sound. There is a tendency for some amplifiers to follow Beecham’s quip – “The English may not like music, but they absolutely love the sound it makes” – in that they make music sound beautiful, but completely free from what makes people passionate about music itself. The Lejonklou Four invert this: they get to the core of what makes people enjoy music. Recommended!" +

Congratulations Fredrik Lejonklou

The Great Exchange - Linn limited time Summer 2017 promotion

The Great Exchange - Linn limited time Summer 2017 promotion

In 2007 Linn pioneered hi quality music streaming with the launch of the Linn DS, delivering sound quality and flexibility unmatched by CD players.

Two years later they stopped making CD players altogether.

Linn want to bring as many loyal customers to embrace streaming but if you still love vinyl they’re giving the chance to trade in a CD player to get the LP12 turntable you’ve always wanted.

So if you’ve enjoyed Mimiks, Genkis, Kariks, Ikemis, Kolektors, Wakondas, Kairns together with the all-in-one Classik Music & Classik Movie systems now is the time to move forward.

Linn recognise the commitment you’ve made to the brand, and we want to make it as easy and attractive as possible for you to upgrade to their latest products.

For a limited period, you can exchange your Linn disc player, or Linn pre-amplifier, for a guaranteed value against any new product:

Pick a Network Music Player, new Speakers, an LP12 Turntable, or even their latest Exakt upgrades—it’s all up to you.

Linn’s latest products offer superior performance, access to vast new sources of digital music and features you just won’t find with a CD player: such as Radio, Space Optimisation, Multiroom and limitless control options.

Plus, each one is upgradeable: new features, services, and even performance upgrades are regularly available.

So whether you want to listen to the radio, use a Computer or NAS to storage your CDs, want to flick music to Airplay to a Linn HiFi or connect your turntable – LINN has is covered and with Hidden Systems we can help get you there.
