• Separate high-speed soft recovery rectifiers, filter caps, and voltage regulators for each channel
• A mono switch can improve the sound of mono and older LPs
• Built-in AC line conditioner to prevent AC noise from polluting the circuits

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 the illumination of the front panel P logo.
