Parasound Halo JC 3+ MM/MC Phono Preamplifier
Dual mono circuitry designed by the legendary John Curl, and board layouts by Carl Thompson.
The Parasound Halo JC 3+ phonostage offers MM or MC support with single-ended input only, and single-ended or balanced output. A mono switch can improve the sound of mono LPs. Variable MC impedance can be adjusted between 50 and 550 ohm.
Only the finest components are used, with Vishay-Dale resistors in the audio path, Vampire 24k gold-plated RCA jacks, and Neutrik XLR connectors.
A triple shield separates power supply and audio circuits, and the design is fully dual mono. The rear panel is also aluminum. The power supply uses high-speed-soft recovery bridge rectifiers and common mode inductors.
