Parasound Releases JC 3+ Phono Preamp

Parasound's new Halo JC 3+ phono preamplifier features independent load adjustment options for moving coil (MC) cartridges and increased power-supply capabilities and updates to its dual-mono module circuit boards.

Parasound says the new Halo JC 3+ phono preamplifier will be available in late December for a retail cost of $2,850.

Parasound is a San Francisco-based audio company that has always tried to walk a fine line between cost and performance. A few years ago the company developed its Halo JC 3 phono preamplifier that provided vinyl enthusiasts a step-up phono preamplifier that offered many high-performance audio traits for a cost that didn’t break the bank.

Feeling the spirit of the holiday season, Parasound has announced the Halo JC 3+, an updated version of the Halo JC 3 phono preamplifier that will be available later in December 2013.

The JC 3+ adds variable load options that offer fine adjustments for moving coil (MC) cartridges for each channel at a range of 50 ohms to 550 ohms via low-noise, dual-gang Vishay manufactured potentiometers.

“Where the JC 3 background was utterly ‘black,’ the JC 3+ black is ‘blacker,’” states Richard Schram, founder of Parasound. ” While these may seem like small details, the JC 3 is already an incredible performer and Parasound is going for that little bit more in the JC 3+.”

Parasound says the JC 3+ produces a MC signal-to-noise of 87dB, which is up from 75dB, and it has increased the gain of the moving magnet (MM) option 1dB to 48dB. In addition, the company has lowered the gain of the MC from 68dB to 64dB to help maintain input levels on some sensitive preamplifiers that were overloaded by the output of the older JC 3 and high-output MC cartridges.

Other improvements include a newly redesigned power supply that features 47 percent larger low-ESD power supply filter capacitors that help to generate more current reserves for increased dynamic capabilities, and a new on/off switch for the front panel illumination of Parasound’s “P” logo.

MSRP is $2,850.
