Product Description

Bluesound BP100 Battery Pack

If you're into vinyl records, then you'll discover that the Parasound Halo JC 3 Jr. Phono Preamplifier is at the pinnacle of analogue audio technology and value engineering. Its “DNA” and circuit topologies are inspired by Parasound's acclaimed JC 3 and JC 3+ phono preamplifiers. The JC 3 Jr. advances legendary designer John Curl’s reputation for designing legendary phono preamplifiers dating back to the 1970s.

Overview

John Curl is a legendary audio designer with several decades of experience, known for designing acclaimed phono stage preamps for known high quality audio brands and known for Parasound. His previous work, the JC 3+, is a stereophile class-A recommended component, which in laymen’s terms means officially brilliant, with the best performance in its category. Now John has no desire to stop creating fantastic quality products and has a never-say-die attitude and so his new JC 3 Jr. is the ultimate value-engineered phono preamplifier which is his most affordable…ever.

Audiophile Performance On A Budget: If you’re trying to get the most out of your turntable with a modest setup then the JC 3 Jr. is for you. The Jr. is the lowest cost product to bear the Parasound name, but don’t let that fool you into thinking that Parasound have lowered the level of quality. In terms of hardware and components there are certain core elements: Vishay-Dale resistors in the audio path, aluminium shielded power supply and audio circuits (with shielded toroid power transformer), high speed-soft recovery bridge rectifiers and common mode inductors, vampire brand 24k gold-plated RCA jacks and also Neutrik brand locking balanced XLR outputs connectors.

Again, certain key fundamentals can be seen in the acceptance of multiple cartridge options and loading options as there are cartridge options for 47k Ohm MM and MC/MI, plus variable MC impedance adjustment of 50-550 Ohms and also designated gain select for 40 dB/50 dB/60 dB unbalanced (46 dB/56 dB/66 dB balanced). On the performance front the shrewd design and performance seen in the larger Parasound Halo JC3+ can be extended to the 'JR', with an RIAA accurate to within 0.2 dB alongside the incredibly consistent S/N up to 94 dB and THD less than 0.02%.

Summary

So if you are searching for the near-perfect phono preamp to really give your analogue system the performance and quality sound it deserves and at a price that won't send you to the dog-house, then without a doubt, the Halo JC 3 Jr. from Parasound is worth your serious consideration.
