Features

- 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

- 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

- 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.

- Ability to turn off illumination of the front panel P logo.

- Now Available in Silver or Black.
