JC3 Manual

October 2011

"As with the JC 1 and 2, the construction quality of the Halo JC 3 is first-rate."

"Like the Vendetta, the JC 3 wasn’t merely quiet, or even really, really quiet-it was silent."

"In every case the portrayal of the recorded acoustic was exquisitely detailed."

"It’s superb at both frequency extremes, and tonally it’s as close to neutral as any component I’ve heard."

"Highly recommended!"

- Brian Damkroger

 "As with John Curl’s legendary Vendetta phono preamplifier, the Halo JC 3 was superbly quiet."

"Looking back through this report, I seem to have used the word superb several times, and justifiably so:

The Parasound Halo JC 3 measured performance is indeed superb."

- John Atkinson

"The internal layout was gorgeous, if like me, you’re into such things. It abounds with top-quality parts including Vishay-Dale resistors and

REL capacitors in critical circuits."

"it’s as quiet as a mouse in hospital slippers."

"And this is key to its bat-sensitive low level resolving power, its ability to peer deeply into the small recess of a musical moment"

"Dynamically there’s a riveting balance of extremes at play, from profound ambient silence to rollicking kick-butt energy."

"this is the kind of resolving power and specificity that make the JC 3 so addictive."

"In terms of real-world performance, the place where most of us actually live, the Parasound Halo JC 3 is the best phono preamp I’ve heard in my system."

"My highest recommendation."

- Neil Gader
