Audio Research GSpre Line Stage/Phono Stage, Store Demo

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 variety of phono 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.
