Product Description
The van den Hul Grail V3 is the latest version of one of the most innovative and advanced phono preamplifier’s available.
Feature List:
- a uniquely 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 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
The van den Hul Grail V3 will deliver you outstanding sound quality with nearly every available modern phonograph cartridge.
