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 ESR 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.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
