PARTTIME AUDIOPHILE BEST AMPLIFIERS, SUMMER 2022 GUIDE—Parasound Halo JC 5
"Just one step down from the highly regarded Halo monoblocks, the Parasound JC 5 is a dual mono design "from the transformer windings on." We found this stereo power amplifier to sound good, first and foremost, with a midrange quality that's rare among solid state amps at this price point. "Inherently neutral, accurate without being dry, no solid state etching or harshness whatsoever, and imaging and soundstage that could compete with similarly priced tube amps." A Reviewer's Choice winner."

Input Audio March 2022
"The Halo JC 5 stereo power amplifier was developed in collaboration with legendary audio designer John Curl. It is designed without compromise for exacting musical reproduction. With its exquisite performance and compelling value, the JC 5 is the new 'amplifier benchmark.'"

Positive Feedback, January 2022
"Many components come along that sit well in our systems and become an integral part of them, even increasing our joy in what we are hearing. However, on rare occasion, we unbox and plug in a piece that truly elevates our entire listening experience—this sums up my time with the Parasound JC 5."

AudioXpress, October 2021
"... I can confidently say that you would have to throw down for much more to better the subjective sound quality. Your entire system—from sources to wiring to speakers—would also have to be exemplary to even match this amp's pedigree and performance. This behemoth is worthy of unqualified admiration; highly recommended."

Part Time Audiophile, April 2021
"Everything about this 400W into 8Ω and 600W into 4Ω with 12W of pure Class A transitioning into Class AB oozes thoughtfulness and attention to detail"

Twittering Machines, April 2021
"My initial impressions listening to the DeVore Fidelity O/93 speakers powered by the gobs-O-music power delivered by the Parasound Halo JC 5 are, in a word, effortlessness."

SoundStage! HI-FI January 2019
"Having heard the JC 5, I realize that it's worth every penny. Its sound delighted me in ways that few other components ever have. By any measure, the Halo JC 5 is a superb power amplifier. I can't recommend Parasound's Halo JC 5 highly enough."

Hi-Fi News (UK) December 2019 - Outstanding Product Award
"This is one fast, hard-hitting amplifier with superb grip on speakers. The JC 5 will please even if you never explore the limits of its performance."

Home Theater Review November 2018
"The JC 5 plays whatever you want the way it was meant to be played. For Parasound to have such stringent design criteria on the JC 5 is impressive indeed. Like its big brother, the original JC 1, the Parasound JC 5 is a stunning amplifier."
