  • Page 2 Gryphon Preamplifier XT. The Gryphon Preamplifier XT is a »prestige product« in the only meaningful sense of the term: a handmade product in very limited numbers based on the extensive research and development efforts of professional audio engineers, a component expert, a mechanical engineer and a designer.

    The sole purpose of every Gryphon product is to recreate as accurate an illusion of the live music experience as is humanly possible. We are successful only if our endeavors move you not to say »What a wonderful amplifier«, but to say instead, »What marvelous music«.

    M A N U F A C T U R E A N D A S S E M B L Y The Gryphon Preamplifier XT is manufactured by a select team of specialists. The fully sealed printed circuit boards with three times the normal quantity of high purity copper are assembled by a supplier of precision medical equipment with strict standards of quality control and pre-inspection of components.
  • Page 5 Moving Coil and RIAA circuits which handle ultra-low level signals. In order to optimize the outstanding signal-to-noise ratio of the Gryphon XT, it should be placed as far away as possible from strong magnetic fields (such as large transformers in power amplifiers, etc.).
  • Page 6 P U R E C L A S S E A M O D E x 4 0 The extremely high bias current means that the Gryphon Preamplifier XT uses a mere fraction of its capacity for even the most demanding signal. Gryphon Preamplifier XT literally »coasts« along, well within its wide operating range with an ease which can be heard as smoother, more coherent reproduction, without grain or suppression of dynamics.

    Use the impedance table to find the correct resistor value. This value is normally specified by the cartridge manufacturer and can be supplied by your Gryphon dealer. Use only a high-quality precision metal film resistor. Mount the resistor as indicated and take special care to avoid »cold« solderings.

    S P I K E S The use of spikes beneath the Gryphon Preamplifier XT allows more efficient isolation from vibration and resonances. Coasters are provided for the protection of furniture. T H E A R T O F G R O U N D I N G In a normal audio system we recommend the use of both grounding posts (if grounding is required at all).
  • Page 10 I N T E R C O N N E C T I O N S Although you probably already have a favorite cable, the Gryphon Preamplifier XT is so revealing that you may have cause to rethink your opinion on this crucial optimum contact. A bad connection becomes a series resistance, with degrading effect on performance.
