LEAK Stereo 230 Integrated Amplifier + LEAK Sandwich 250 Loudspeakers

Movie and Music enthusiast as its heart

The LEAK STEREO 130's all round performance is engaging, detailed and refined. Detail, timing and dynamics excel, regardless of source or medium. Designed for the modern-day music enthusiast with a nod to our heritage, the LEAK STEREO 130 does not discriminate when it comes to expresiion and enjoyment of your music reproduction.

Headphone Users

The LEAK STEREO 230 uses a dedicated amplifier circuit with current-feedback technology for the headphone output. Equal in performance to standalone headphone amplifiers, beyond the price class of this complete system, the design offers high-speed output signal transition thanks to a high slew rate. The result is a dynamic, detailed and engaging performance with all manner of headphone types.

Arc de Triomphe

Equipped with an Audio Return Channel(ARC) connection, the LEAK STEREO 230 integrates perfectly for home AV applications, bringing the LEAK Hi-Fi pedigree to your screen, too.

A major loudspeaker invention

Throughout the history of broadcasting and recording, certain exceptional developments have become milstones in the progress of sound reproduction.

One such milestone was the world’s very first low distortion amplifier – the famous original Leak Point One, in 1945.

Another was the pioneering major breakthrough with the invention of the fantastically rigid Leak sandwich cone diaphragm – which was demonstrably of great strength and many times stiffer than all conventional forms of cone, of its time.

Axial pressure response of Sandwich 1250 Loudspeaker

To understand the impact of this innovation, one must remember that to obtain low distortion, the movement of a loudspeaker diaphragm, or cone, should follow as accurately as possible the waveform of the signals applied to its voice coil.

This results in significantly larger areas of the cone vibrating in motion, uncontrolled by the voice coil.

These uncontrolled emotions produce transit “hangover”, amplitude distortion (peaks and troughs in the frequency response) and intermodulation distortion (lack of clarity of spurious tones).

The Evolution of the Sandwich Cone: Engineering Excellence from 1961 to Today

Originally presented in 1961, the Sandwich used engineering and design principles applied to airframe construction.

Now, reintroduced and re-engineered with modern-day learnings, the new Leak Sandwich cone comprises of a stiff aluminium skin for the outer surfaces (where the stresses are greatest) bonded to a thick core of a polymethacrylimide (PMI) based structural foam, often used aerospace and the automotive industries.

This applied, precision-engineered use of the most suitable materials in optimum proportions and dispositions gives immense rigidity.

This means the Leak Sandwich cone reproduces the signal applied to the voice coil, totally free from mechanical break-up and its associated distortions. The result is a remarkably smooth frequency response, free from violent peaks or troughs over a very broad frequency range, indicative of an excellent, transient response.

The Unseen Power of Speaker Cabinets: Advancements in Acoustic Design

It is not often sufficiently realised how profound the influence of the loudspeaker housing (the cabinet) is on the overall acoustic performance.

Its design requires a great degree of electroacoustic knowledge as a design of the motor units themselves.

The new Leak Sandwich cabinet benefits from 60 years of technological development since the original.

The structure consists of a composition of MDF and composite board, thus creating a second ‘sandwich’ reference, with the boards layered for optimum cabinet strength.

While the new cabinet fuses intelligent bracing with this ‘sandwich’ of materials, it also maintains a specific front-rear bracing, with the distinct, visible countersunk screw on the rear – a famous trait of the original.

The Perfect Fusion of Technology and Design: Introducing the New Leak Sandwich Loudspeaker Models

The technology found within Leak audio devices presents science and innovation in abundance, yet the industrial design often draws favourable attention.

Just like the warmly received Leak Stereo 130 and 230 integrated amplifier models, the new Leak Sandwich 150 and 250 loudspeaker models maintain the understated, classic Leak styling. Finished in a sumptuous walnut, real-wood veneer, the cabinet is decorated with an aluminium trim insert matched and finished to the same exemplary standards of the driver trims and cone materials.

The decorative grille cloth is purpose chosen to match the classic Leak styling with a specification for maximum acoustic transparency.

A keen eye will also notice that the new Leak Sandwich 150 and 250 are supplied in perfectly matched pairs with a ‘handed’ array presentation.

Much more than continued industrial design traits, the meticulous placement of each driver is considered to the nth degree, thus enabling a projection of a truly precise stereo soundstage.

Elevating the Experience: The Perfect Stand Solution for the Leak Sandwich 250

Such is the format of the Leak Sandwich 250, many traditional stands would not allow for sufficient presentation of this loudspeaker.

To address this consideration, the Sandwich 250 is complemented by a precision-measured plinth that positions the loudspeaker’s driver array at the optimum level and position.

The result is a finely finished loudspeaker and matching stand combination of furniture-grade quality, that eliminates any compromise of the listening experience for the proud owner.
