GaN Amplification – A New Direction for the Robson Masterpiece Power Amplifier
Our new Masterpiece Stereo Power Amplifier 500W represents one of the biggest changes we have made to a Robson amplifier design for some time. At the heart of the new amplifier is advanced Gallium Nitride, or GaN, Class D amplification, combined with our own newly developed power supply technology. For us, the reason for making this change is not simply efficiency or power. As always, the decision comes down to sound. What is GaN amplification? Traditional amplifier output stages generally use silicon-based transistors. Gallium Nitride is a newer semiconductor technology capable of switching significantly faster and more efficiently. In an audio amplifier this allows the output stage to react extremely quickly to changes within the music, while keeping noise, distortion and unwanted losses exceptionally low. That speed is particularly important when reproducing fine transient information – the leading edge of a piano note, the attack of a drum or the smallest changes in a vocalist’s performance. The aim is not to make the presentation sound faster or more impressive, but to allow the amplifier to get out of the way of the recording. To The product Class D does not mean digital There is still a common misconception that a Class D amplifier converts music into digital information. It does not. A correctly designed analogue Class D amplifier can maintain the music signal entirely within the analogue domain. There is no need to convert a vinyl source into digital data simply because the amplifier uses Class D technology. That was particularly important to us. Many Robson customers use both high-quality digital sources and vinyl, and our objective has always been to retain the natural texture and character of both. Why GaN makes a difference Earlier generations of Class D amplification sometimes gained a reputation for sounding clinical or lacking the natural character associated with the best Class A and A/B designs. Modern GaN devices allow the switching stage to operate far more quickly, reducing many of the compromises associated with older designs. In listening terms, this can translate into: Exceptional transient speed Very low noise and distortion Greater control of demanding loudspeakers Deep, well controlled bass Excellent separation and fine detail A wide and holographic soundstage A smooth and natural presentation Most importantly, the technology provides enormous power without losing the delicacy and realism that make a recording believable. Robson’s Approach We have combined the new GaN amplification stage with our own power supply technology rather than treating the amplifier module as a finished solution. The power supply, mechanical construction, component selection and final voicing all play an important part in how an amplifier ultimately performs. The result is the new Masterpiece Stereo Power Amplifier 500W – an amplifier designed to provide effortless power and control while retaining the organic, analogue character we want from a Robson system. For us, GaN is exciting not because it is new technology, but because it allows us to get closer to what we have always been trying to achieve: greater realism, space, detail and ultimately a stronger connection with the music. The Masterpiece Stereo Power Amplifier 500W is available for demonstration. Please contact us to discuss the amplifier, system matching or arranging a listening session. Get in touch

Introducing the Robson Acoustics Masterpiece Cable Range
A high-end audio system can only perform at its best when every part of the signal path is given equal consideration. The new Robson Acoustics Masterpiece Cable Range has been created to complement our finest electronics, with conductor quality, shielding, dielectric materials and mechanical control carefully considered throughout. The range launches with two products: the Masterpiece Interconnect Cable and the Masterpiece Power Cable. Masterpiece Interconnect Cable An interconnect carries a low-level audio signal between components, making protection from interference and signal degradation essential. The Masterpiece Interconnect uses high-purity copper conductors arranged in a multi-layer construction. The individual strands are wound in alternating directions to create a stable conductor geometry, while polypropylene insulation provides a low-loss dielectric around the signal conductors. A comprehensive shielding system combines copper foil and braided copper layers to protect the signal from radio-frequency and electromagnetic interference. Internal damping and the finished outer braid further reduce the effect of mechanical vibration. With substantial 15 AWG conductors measuring 1.65 mm², the cable is designed to preserve low-level information, tonal texture and spatial detail without adding an artificial character of its own. The result is a clean, open presentation with precise imaging, natural tonal balance and excellent resolution. To The product Masterpiece Power Cable The power cable is the final connection between an audio component and the mains supply. Its job is to deliver current reliably while limiting the influence of surrounding electrical and mechanical noise. The Masterpiece Power Cable uses large 11 AWG conductors with a cross-sectional area of 4.02 mm². Its high-purity copper construction provides a low-resistance path capable of supporting the instantaneous current demands of power amplifiers as well as the more delicate requirements of source components and pre-amplifiers. Audio-grade fluoropolymer insulation surrounds the conductors, while copper foil and braided copper shielding provide extensive protection from electromagnetic and radio-frequency interference. Specially selected damping materials are also incorporated into the cable structure to help control vibration and resonance. At approximately 17 mm in diameter, this is a substantial cable designed for serious audio systems. Its combination of current capacity, shielding and mechanical stability allows connected equipment to perform with greater composure, particularly during demanding musical passages. Listeners can expect authoritative bass, improved dynamic freedom and a quieter, more focused presentation. To The product Designed as Part of the Masterpiece System These cables were developed to match the same priorities found throughout the Robson Acoustics Masterpiece range: carefully selected materials, uncompromising construction and musical realism. They are natural partners for our Masterpiece pre-amplifiers, power amplifiers and phono stages, but can equally be used to enhance other high-performance analogue and digital systems. A Masterpiece Speaker Cable is also in development. Based on the proven design of our Reference Speaker Cable, it will feature an upgraded outer braid and handcrafted ebony detailing to complete the range. The Robson Acoustics Masterpiece Cable Range is not about changing the character of a system. It is about preserving the signal, controlling interference and allowing exceptional equipment to reveal everything within the recording.
