Parasound JC1

The JC-1 Amplifiers designed by famous Audio Designer John Curl are well-known in the Hi-End Audio Community.  I have listed Reviewer's Accolades and their Specifications later below.  

These are virtually brand new in terms of very minimal use on them as they were used in a second system that I didn't have much time to listen through due to my busy schedule.  They are cosmetically flawless other than normal connector use to attach speaker cables and interconnects.  They have at most 4-months of use in total.  I am the original Owner and the environment is smoke-free.

Reason for selling?  I am embarking on a Master's Degree and am liquidating most of my stereo gear to assist with funding it.  A JC-2 Preamp that was part of this System is listed in a separate Audiogon Ad.

I have not sold in some time, but in the past, I have sold 39 Items on Audiogon and had a perfect (100%) satisfaction Record.  I am an M.D. by background and most people know we take very good care of our possessions, especially audio equipment. 

Any serious offers will be entertained.  I am happy to answer questions, but as I have a busy schedule with both working and studying, I usually only look at e-mails at the end of each day,  So please be patient we me in getting back--It will be the same day, but depending on your time zone, it may be late or very late that day.

Buyer pays for shipping (2--double boxes).  Please at 2.9% to final offer to cover PayPal Fees that will be incurred.

Thank you for your interest!!

Accolades for the JC-1 Power Amplifiers:

Home Theater Review:

“When Parasound announced it was releasing a line of products with legendary designer John Curl under the moniker Halo, the press release alone was spank material.  At the top of the product line sat the JC1 monaural amplifier, named after the man responsible for bringing it into existence, John Curl.  The JC1, when it was released, ranked among the most coveted pieces of audio gear in history and remains on that list to this day. 

Hi-Fi News (UK):

"...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

Enjoy the Music:  

"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." 

Positive Feedback:

"...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." 

The Absolute Sound: 

...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

Stereophile Magazine:  

"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
