About
Ooberpad proudly presents to you Parasound Halo JC 3 Jr. Phono Preamplifier. Parasound's brand new Halo JC 3 Jr. phono preamplifier is a simplified version of the company's award-winning flagship JC 3+ and they sound almost identical. In most systems, the difference is not that nuanced. The JC 3+ sound is a tad more refined and power-packed because its component parts and construction are more exorbitant. JC 3 Jr. is stunningly close but is slashed half in its price.

Benefits of Parasound Halo JC 3 Jr. Phono Preamplifier:
Stands Uncompromising in its Amazing Sonic Character
Parasound stood uncompromising while delivering the amazing sonic character of the JC 3+, which is what everyone appreciates about the brand. The Halo JC 3 Jr. retains this sonic signature, adhering to the highest degree of finesse, pin-point imaging and a comprehensive range. The circuit topology is closely related, and circuit boards were meticulously crafted by Carl Thompson, John's circuit board partner dating back to his legendary Vendetta phono stage. Both use premium parts such as REL caps, Vishay-Dale resistors, Neutrik and Vampire connectors, and relays for muting and mono select.
What's different is that both channels of the Jr.'s gain and EQ circuits are built on a single board, behind a single shield, rather than on separate boards with individual shielding in the JC 3+. Jr.'s power supply is shared by both channels rather than dual-mono in the JC 3+. It still employs the same high-speed/soft-recovery bridge diodes and common mode inductor to eliminate background noise. These alterations enabled Parasound to utilize a new low-profile Halo chassis that is cost-effective to build. It's drop-dead gorgeous and will definitely have a long line-up of future products.
