VAN DEN HUL The Grail SX phono preamplifier

Symmetrical phono stage With this product you will become the owner of one of the most innovative and advanced fully balanced phono preamplifiers currently available.

The new and redesigned circuit board has improved the overall sound quality, especially in the stage presentation and detail resolution.

Equipment list:

• a specifically designed phono preamp section, unique in the world
• A new and revised board for the predecessor Grail SB/SE
• RIAA – equalization using coils only, no capacitors in the filter that affect the sound
• special circuit board material with golden conductor tracks
• The circuit board has a special attachment to prevent microphonic effects
• Special equipment with wooden feet prevents mechanical energy storage
• Low-noise moving coil input stage without annoying noises even with low-output pickups
• Automatic adjustment of the input stage to moving coil pickups, no resistors required for adjustment
• Ability to compensate for pickup sensitivity (level adjustment)
• Avoid coupling capacitors in the signal path as much as possible
• Strictly separated amplifier sections and circuit layouts deliver a very natural sound
• Inputs: two turntable inputs, one for MC cartridges either balanced or asymmetrical, another for MC only asymmetrical a shielded transformer is placed in an external enclosure to avoid hum and noise
• The power supply with gyrators for each amplifier stage delivers very high noise reduction the external transformer is available for different mains voltages
