The Vinyl Corner: Parasound Ships Halo Phono Preamp

December 14, 2010 By Home Entertainment Editorial Staff

Parasound, the San Francisco-based manufacturer of high-end audio components, has announced that it is now shipping the first production run of its much-anticipated John Curl designed Halo JC 3 Phono Preamplifier. Nearly 20 years ago Curl also designed the Vendetta Research SCP2B that is still regarded by many audiophiles as the preeminent phono preamp. As of this writing, the JC3 is so new, we beat the Parasound website to the punch; we could find no reference to it yet.

The new Parasound Halo JC 3 is a high-performance dual-mono phono preamplifier. Like all phono preamplifiers, the JC 3 must multiply the tiny audio signal generated by a high-end low-output moving coil or moving magnet phonograph cartridge and make it strong enough to deliver to the input of a line level preamplifier. The JC3 uses the smallest possible amplifier circuit and the least amount of copper to reduce potential noise and distortion.

The JC 3 uses dual mono power supplies with an R-core rather than a toroidal transformer - toroids have very high capacitive coupling, which enables noise on the AC line to pass into the power supply and ultimately into the phono gain stages.  Protection from AC noise is further enhanced via a built-in AC line conditioner.


To feed your internal spec beast: The JC 3's signal to noise ratio is 83 dB with the MM input and 73 dB for MC, and the 20- 20kHz RIAA curve is accurate to within 0.2 dB.  THD is .005% at 20 kHz. 
MSRP $2,350
