  • Designed by John Curl - creator of the legendary Vendetta Research phono preamp
  • Inputs and outputs use Vampire brand 24k gold-plated RCA jacks
  • Balanced outputs use Neutrik brand premium XLR jacks
  • MM 47k ohm, MC 47k ohm or MC variable 50-550 Ohms
  • RIAA accurate within 0.2 dB
  • Exclusively Vishay-Dale resistors in the audio path
  • Triple shielding; low-carbon mild steel partitions isolate the power supplies & AC wires
  • Dual mono design; each audio channel is separately enclosed in its own extruded aluminum enclosure
  • Separate high speed-soft recovery rectifiers, filter caps and voltage regulators for each channel
  • Superior R-core type power transformer
  • Mono switch can improve sound of mono and older LPs
  • Built-in AC line conditioner to prevent AC noise from polluting the circuits
  • AC polarity reverse switch can reduce hum in many systems
  • Non-magnetic aluminum rear panel for purest sound
  • Turn On Options switch: manual or auto with 12v trigger input
  • Premium detachable heavy gauge IEC AC cord
  • 2u Chassis, rack mountable with HRA2 (sold separately)

  • 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.
  • 82% larger R-core power transformer greater reserve for more low end impact.
  • Ability to turn off illumination of the front panel P logo.
  • Now Available in Silver or Black.
