JC 1 Amplifiers
The JC 1 Monaural Amplifier might possibly be the world’s finest power amplifier. Parasound, John Curl and CTC Builders collaborated in the design of this amplifier to create a new standard for elegance, sonic precision and value. The JC 1 provides 400 watts into 8 ohms with 135 amps of peak current. Its 25 watts of pure Class A power is user-switchable to 10 watts of Class A power when heat dissipation is a concern. Other features include balanced XLR or unbalanced RCA connectors, a 12v trigger, an audio sensitivity trigger, adjustable turn-on delay, and a ground lift switch. Advanced circuitry, premier parts selection, unequaled sound quality, and stunning design are bound to make this amplifier a legend in its own time.
JC 1 Reviews: 2003 Amplifier of the Year, Stereophile Stereophile, December 2003 Sam's Product of the Year "Before you blow $10k-$20k or more on some amps that were recommended by a reviewer who didn't buy them, give a listen to the Parasounds, which this reviewer did purchase." "Don't buy an amp without hearing these, even if you can't afford them." - Sam Tellig Stereophile, February 2003 "It took but a few seconds for me to absolutely fall in love with the Halo JC 1." "Powerful, refined, smooth, organized, dynamic, transparent, and rhythmically supple, the JC 1 offered a combination of attributes that added up to many weeks of listening pleasure. I'd be happy to have it go on indefinitely - as, no doubt, will many of you." - Michael Fremer Positive Feedback, August 2003 "...Parasound's Halo JC 1 amplifier, is among the most precisely nuanced amplifiers I know, able to draw the slightest and most delicate of musical expressions, to make the subtlest distinctions. It can also rock you, like your back ain't got no bone, 'cuz it's a brute. It is the amp for all seasons." "It has the ability to produce a believable facsimile of spaciousness, that 3-D sound-staging that makes the illusion of space between the instruments nearly tangible; the ability to produce timbral, harmonic, and dynamic accuracy that results in what we call 'inner detail'; the ability to produce delicate refined purity of tone one moment, and then bowl you over with A BIG WALL OF SOUND the next." "...these amps are truly outstanding, among the best I've ever heard, and the best I've had in my system." - Max Dudious EnjoytheMusic.com, November 2003 "Beautiful Brutes." "The JC 1s rank with the best amplifiers I have heard in recreating a multideminsional sound field." "They pump out seemingly effortless power no matter how insanely loud I push them, with never any sense of strain such as you hear when an amplifier is running out of gas." "The JC 1s are also capable of wondrous delicacy, and the kind of transparency that makes you feel that you're hearing every instrument, every voice, but never at the expense of the musical whole." "To be able to buy these robust, delicate, emotionally involving, brilliantly conceived and executed music recreators for $6,000 seems to me little short of a miracle." - Wayne Donnelly The Absolute Sound, June 2003 "...I was impressed with the remarkable speed, clarity, transparency, and focus of these amps straight out of the box." "The high frequencies were to-die-for silky smooth, crystal clear, and abundantly detailed. The kind you could listen to all day long without fatigue." "There wasn't anything that didn't sound great on the JC 1." "I was left with an ear-to-ear grin on my face that lasted the rest of the week." - Sue Kraft HiFi News (UK), January 2004 "...incredibly effortless and natural." "This amplifier certainly held me captivated and entertained, drawing me into the music." "If you want to lose yourself in the music, there are precious few components as good as the JC 1." - David Allcock Bound for Sound, #149 "Clean, clean, clean." " I've heard $30,000 power amps not sound so nearly perfect." - Martin DeWulf
