no longer for sale

Used for a few weeks, purchased new, locally. Selling due to upgrade, works flawlessly as new. 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. • Stereo Vacuum tube Line and Phono preamplifier with Headphone amplifier in one attractive package. • Pure Class-A differential amplifiers in the Line stages, no feedback. • Pure Class-A SE amplifiers in the Phono stages, no feedback. • VF display with Blue LED's for Phono Loads and mode selected, and rotating Volume & Input Select encoder. • Balance and SE input/output. • 7 levels of voltage regulation and a low noise R-core power transformer. • Phono stage features low noise JFET inputs and 6H30 outputs as well as programmable loading. • Line stage features low noise JFET inputs and 2 parallel 6H30 outputs. • Features custom designed coupling capacitors in the line and phono stages. • +12v trigger output to turn on power amplifier and other system components. • Low distortion vacuum tube headphone amplifier designed for driving a wide impedance range, 30-300 ohms. • Removable 15A IEC power cord.
