Products The GRAIL

The GRAIL With this product you will be the owner of one of the most innovative and advanced phonograph preamplifier's available at the moment.   “The Grail” is a really dulcet phonograph preamplifier, specifically designed bearing ultimate performance and reliability in mind.    Featurelist:   • a specific designed Phonograph preamplifier section, unique in the world • Phonograph RIAA - equalization with coils only, no sound impairing capacitors in filters • special printed circuit board material with gold conducting paths • the printed circuit board has a special seating to evade microphonics • special equipment foot made of selected wood avoids mechanical energy storage • low noise moving coil input stage, no annoying noise even with low-output cartridges • automatic adapting input stage for moving coil cartridges, no matching resistors needed • possibility to compensate phonograph cartridge sensivity (level adjustment) • cut out of coupling capacitors in the signal path as far as possible • strictly separated amplifier sections and circuit layout deliver a very natural soundstage • inputs: two phonograph inputs, one for MC cartridges, one for MM or MC high-output • a shielded transformer is placed in an external housing to avoid hum and EMI noise • power supply with Gyrators for each amplifier stage deliver very high noise cancellation • the external transformer is available for different mains voltages    Designed to provide high-end audio, “The Grail” will deliver you outstanding sound quality with nearly every available modern phonograph cartridge.   TECHNICAL SPECIFICATIONS   Mains Power 110 or 230Volt, 50/60Hz Power consumption:  7 Watts Temperature operating range:  from 15 up to 30deg.
