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.
