Van den Hul Grail
Innovative and advanced phonostage from van den Hul. “The Grail” is a really a dulcet phonostage, specifically designed bearing ultimate performance and reliability in mind.
Two Moving Coil (MC) Inputs via RCA
Feature list:
- a specific designed Phonograph preamplifier section
- 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 sensitivity (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 MC phono inputs
- 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.
