CaracterísticasAudio Research proudly introduces the G-series of vacuum-tube electronics, in homage to the great astronomer and scientist, Galileo Galilei.
As the world’s oldest continuous manufacturer of vacuum tube electronics, Audio Research builds upon its accumulated expertise gained over 44 years of high performance audio design and focuses it on a new series that provides superlative music reproduction. GS represents a new exploration into the past of Audio Research – a continuation of refining performance in a beautiful design aesthetic. Inspired by classic Audio Research components from the 1970’s, the new appearance is modern yet comfortingly familiar. Much as Audio Research has expanded the boundaries of what is possible in music reproduction, the GS series adds a visual refinement and elegance befitting the performance of this series.
The GSPre is a full-function vacuum-tube preamplifier combining a line and phono sections, with a revelatory headphone section for more intimate listening. Built around a sophisticated balanced circuit, with great connectivity and ease of use, the GSPre provides great flexibility in addition to its sublime sound.
The GSPre is the nerve center of a system – not only directing signals and providing attenuation, but also interpreting and deciphering complex signals to create a musical story with the drama and intrigue befitting of your favorite songs. The job of a preamplifier is to do its work discretely, leaving the musical signal with as little signature as possible yet still unraveling the chapters that comprise the lyrical narratives of the source material. With decades of expertise creating some of the finest preamplifiers ever produced, the GSPre is certain to continue the legacy for which Audio Research has built their reputation.
The GSPre is both a line stage and phono stage, with programmable functionality and flexibility, making it the perfect solution to adapt and grow in your system. The phono stage is no mere afterthought, but a separate, vacuum tube-powered circuit providing enough gain for a whole variety of cartridges. When listening conditions require a more personal experience, the GSPre also has a headphone amplifier capable of driving a range of headphone impedances. The front panel layout is designed to simply and clearly display all functions and information, and integrates beautifully with the rest of the chassis and the G-Series amplifier.
