Description

 

The GRAIL SB (Balanced)
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.

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 SB” will deliver you outstanding sound quality
with nearly every available modern phonograph cartridge.
