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. TECHNICAL SPECIFICATIONS Mains Power: 115 or 230Volt, 50/60Hz Power consumption: 7 Watts Temperature operating range: from 15 up to 30deg.
