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 SB” is a really dulcet phonograph preamplifier, specifically designed bearing ultimate performance and reliability in mind.

Feature list:


  • 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:


three phonograph inputs, two 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
