How the JC 3+ improves on the original JC 3:

  • Variable MC load adjust independent for each channel from 50-550 ohms with dual gang potentiometers specially made for Parasound by Vishay.
  • Curl-Thompson tweaked circuits to further reduce the JC 3 silent background noise.
  • 24k gold plated copper traces on phono module boards for utmost conductivity and most transparency/detail in the music.
  • 47% larger low ESD power supply filter caps greater reserve for head-snapping dynamics.
  • Ability to turn off illumination of the front panel P logo.
