Description

Features:

  • 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
