"Parasound has long been admired for their preamplifiers and power amplifiers. It is like listening to speakers with speaker grilles vs without when you compare non-modded JC1 to Empirical Audio modded JC1. • As in the JC 1, the JC 1+ input stage uses hand-matched pairs (footnote 2) of Toshiba 2SJ74 P-channel and 2SK170 N-channel J-FETs. Drafting on the success of the original JC1 mono block designed by John Curl, Parasound released news this week that it will be following up their flagship with a new product slated for Q1 of this year. So, in Australia, if some one wants to buy an Aston Martin Vanquish or Lamborghini Aventador with V12 engines, that would cost them both kidneys, both lungs and both testicles :-) ....... And if you want the Veneno Roadster, your body and soul is the price. Upgraded and enhanced, Parasound has added more than ‘go-faster’ stripes onto its new phono amplifier. Toshiba had the process knocked, and produced them by the freight car load. "Doing so has proved that extremely high performance-per-dollar is still possible today when a company leverages decades of experience, and is spearheaded by a legend." The overall tonal balance of the new Halo JC 1+ is exceptionally evenhanded, offering vibrant, lifelike tone color and full, dense textures. At least in the JFET world relevant to this discussion, much of their activity has been to clone the Toshiba designs. Quite honestly, if I were some of those competitors, I'd be more than a little concerned! This result was a spectacular amplifier that yielded 400 watts into 8 ohms, 800 watts into 4 ohms, and 1200 watts into 2 ohms, with no observable compromise! Parasound Halo JC 1 Monoblock Amplifier High value at a low(ish) price! It's hard, again especially for P-channel devices. 2. The detail and warmth is impressive and rich. Collection in person. Footnote 2: J. Gordon Holt and I visited John Curl in 1987 and witnessed him hand-matching small-signal FETs for use in the Vendetta phono preamplifier. Parasound A31 Three Channel Power Amplifier Parasound Halo P 6 Preamplifier & DAC Reviewed Parasound 275 v.2 Stereo Amplifier Reviewed Parasound Halo Integrated 2.1 … Maybe that trend is spreading into the solid-state "realm"? Parasound, Parasound Product, Products reviews, Parasound Review 2018 Design. In their pursuit to achieve the best possible electrical design, layout, and to use the best parts, John designed the circuits, Carl handled board layout and design (having done the circuit boards for the Vendetta Research phono stage, and the Parasound JC 1, JC 2 BP, JC 3+ and JC 3 Jr), while Bob selected the actual constituent parts, hookup wire, connectors, and terminals that populated Carl's boards, voicing the final result. There just isn't the ready availability of film caps in the varieties found with through hole components. Linear Systems presently makes some low-noise JFETs and Sanken makes some transistors for audio driver applications. In my system, they served up the lowest registers with a remarkably refined level of control, ample detail, and unusually genuine pitch definition. If they are, indeed, truly "great/legendary", shouldn't it be well within their capability to develop an alternate design that uses more readily available devices? However, production models are now available in a silver finish as well. https://content.kemet.com/datasheets/KEM_A4029_ALC10S.pdf in what engineering realm does "no-longer-manufactured" mean "obsolete" ??? Parasound, builder of preamplifiers and power amplifiers, was started in 1981 by Richard Schram, in San Francisco, California. Audionet MAX monoblocks, Channel Islands Audio D●500 MkII Monoblocks (Putzeys based Class D), Channel Islands Audio VMB●1 Monoblocks. In November 2015, with the kids grown and out of the big 5-bedroom, 3-floor house, we moved to a smaller home situated on nearly two acres in north-west Goshen, IN. I have had any number of audiophile and musician visitors' remark on the power of the listening experience as witnessed from my chair. Their effect while powering my reference system was one of affording an overall sense of relaxation, of a warm invitation to listen, allowing me to drop all presumptive concerns about listening to a complex reconstruction engine, a conglomeration of electro-mechanical devices, and simply bask in the musical gestalt of the recordings I played. In black or silver finish, the Halo JC 1+ will be available from authorized Parasound dealers in Q1 2020, … Long known for its enveloping rich sound, I'll admit to being more than merely interested to see just what this updated iteration of such a revered and celebrated amplifier could do. The trend now is for entire systems to be built into a single chip. The resultant original Parasound Halo JC 1 was a collaborative design of the highest order. Doing so has proved that extremely high performance-per-dollar is still possible today when a company leverages decades of experience, and is spearheaded by a legend… I will round out this point by mentioning that he designed and built the electronics for both Mobile Fidelity's SuperMaster, and David Wilson's UltraMaster, tape recorders, head amps for SOTA, Michaelson & Austin (TVA), the Dennesen JC-80 preamplifier, as well as creating loads of custom electronic gear for the Grateful Dead. product knowledge and to leverage their general audio experience, are simply wonderful. He did business as TG Audio Labs (reputedly standing for "Tough Gristle"), and was revered almost as a legend for both his ability to clearly hear and identify the sonic differences between materials and brands of audio parts as well as for his own TG branded cables and products. The Parasound Halo JC 5 certainly lives up to the buzz. (Bit like exotic V8 V10 V12 muscle cars) I'm now driving a 2lt twin turbo buzz box, JUST NOT THE SAME!!! Parasound Halo JC 1 Monoblock Amplifier High value at a low(ish) price! Richard has since shared with me that because they felt that they had so much riding on the introduction of the JC 1, that they had built a number of pre-production units, identical to subsequent serial production models, to be able to vet it against as wide a range of demanding state-of-the-art loudspeakers as was reasonable. Room taming is achieved with the use of RoomTunes Corner Tunes, two Echo Tunes (one each at the tweeter's primary reflection points on the ceiling), and the stunningly effective Shakti Innovations Hallographs. I can tell you that if I were shopping for a pair of monoblocks under $25,000, the Parasound Halo JC 1+ would be my first choice. Parasound JC-1 power amplifiers. Halo is our premier line with a reputation for going head-to-head with the most expensive equipment on the market, while costing a fraction of the price. I disagree. Amusingly enough, when that request was granted, I was told that, just as Henry Ford had offered the Model T in 1909, I could have my JC 1+ in any color I wanted, so long as it was black! At 83lb, the JC 1+ is 30% heavier than the JC 1. External differences Aside from the need to create new circuit board layouts and have SMT/SMD assembly capability, certain audio companies would have us believe that leaded/through-hole parts are "good" and that surface-mount parts are "bad". And while the original JC 1 used nine pair of output transistors, the 1+ now employs 24 beta-matched 15A, 230V, Sanken 60 MHz bipolar output transistors in twelve compliments. The company’s products are well regarded throughout the hi-fi and high-end home cinema sectors, receiving many glowing reviews and are much sought after by music and movie lovers across the world. If you are unfamiliar with the name John Curl, you clearly haven't been around the audio industry long. At first look the Parasound Halo A 51 is an appealing and robust amplifier accented by brushed metal finish. This is the force that has been linked to Parasound's Halo C1 pre/pro ever since its trade-show debut a few years back, and it has only gained momentum with each successive instance of display without delivery. Those who know me (or have read my work over the years) know that my system MUST be tonally accurate, strikingly neutral, stunningly transparent, and jubilantly musical. In black or silver finish, the Halo JC 1+ will be available from authorized Parasound dealers in Q1 2020, with a U.S. retail price of $8,495 each. It features a newly designed cascode circuit driver stage that integrates with Bybee Music Rails™, active high-frequency noise filters from Bybee Technologies. An additional $1500 retail value. None of the companies I've worked for would tolerate such a situation. The JC 1+'s shielded input- and driver-stage circuit boards use an FR408 substrate, a substance that was developed for ultra-high-speed applications in supercomputers and aerospace. Someday maybe I will own pair of the the JC1 + :) .. Add to Compare . Further, it shares its predecessor's desirable trait of delivering its first 25 watts in pure class A, with full power rated all the way down to 2Hz! I owned a pair from about 2006 to 2019 and used them with two different highly regarded speaker systems. First, hats off to Parasound for not bowing to convention and badging its new, hot-rodded version of the original JC 3 phonostage with the shop-worn cliché “Reference” or “Signature Edition.” And second, and more importantly, if you’re a current owner of the Parasound JC 3 phonostage, don’t panic. Finally, Parasound says that the front panel design not only matches the updated Halo family appearance but also complements the inner beauty of the JC1+. It's curious to note that some tube amp consumers, by comparison, seem to have no qualms about the use of new-old-stock/out-of-production parts. Neither are necessarily drop-in replacements for "obsolete" devices, so some redesign effort could well be required to convert to their use. There are precious few companies making JFETs these days. http://www.dnm.co.uk/capacitors.html, The slit-foil caps were originally sourced from BHC, which was acquired by Vishay/Kemet. What would come to be known as the Parasound Halo JC 1 amplifier arose out of modifications that CTC Builders performed on the Parasound HCA-3500 between 1999 and 2001. I've not heard any other monoblock entrant at or even close to this price that is able to recreate so many aspects of music with a more authentic voice. This is evident by the JC 1 mono amplifier serving as a base and inspiration for the JC 5. Great Amp and the price is a steal!! I bet the tube guys had similar thoughts back in the boom days of tube based amplifiers. Apparently the semiconductor fabs no longer manufacture high-performance but low-profit, complementary, small-signal J-FETS that get anywhere close to the performance of those used by Parasound, Ayre, and others. Therefore it is impossible to hear amplifier distortion thru this type of speaker. Normally a $4.5K price offered at $3K. Audience frontRow AC Cables, Audience Au24-SE HP and LP powerChords. ! The JC 5 is a 400-watt per channel stereo amplifier designed by John Curl that combines design elements of two top-of-the-line Halo JC 1 monoblock power amplifiers into a single chassis the same size as one JC 1. Would you find the phrases "not for new design" or "end of life" less offensive? But to the point here, while Richard Schram, President and CEO of Parasound Products, Inc, established the Parasound brand in September 1981, John Curl has been working on Parasound product design since 1989. In place of the original's ground-lift switch, there is now a switch to allow the amplifier's gain to be set to Normal or Low, the latter reducing the gain from 29dB to 23dB for use with preamplifiers whose volume controls can't be used in their optimal positions or when the user's speakers are sufficiently sensitive that hiss can be heard. That total capacitance figure of 22,400 on page 1 sure seems low. It employs Harris hyper-fast, soft-recovery bridge diode rectifiers, REL & Nichicon Muse capacitors, as well as DC servo and relay protection circuits. The first word that comes to mind while they were in play driving my VSA VR-55 Aktives was natural. Though I had inquired of Parasound's Director of Sales, Phil Jackson, back in late 2018 as to my doing a review whenever the reimagined JC 1 might make its way back into the Parasound roster, when the January 16, 2020 Press Release landed in my inbox, I immediately requested a listen! Any thoughts about how the SQ compares to your Pass Labs XA60.8 amps? It more than comfortably competes with, and actually bests, many contenders who have long enjoyed favored status in that lionized class of more refined and inspired amplifier designs. As the JC 1+ costs $16,990/pair, it is significantly more expensive than its predecessor in real terms, but still less pricey than many other high-power, high-end amplifiers Stereophile has reviewed in recent years. I still have that review sample of the SP-10, which I purchased following the reviewandusedformanyyears.Sincethen,Ihavemadetheacquaintanceofsome preamplifiers that are even more neutral than the positively neutral SP-10. By the time the last one rolled off the Parasound assembly line in 2018, after more than a decade-and-a-half of production, they were still remarkably priced–at just $4,495 each. http://www.supertech-elec.com.tw/electronic/ECAPS/Audio-2T.htm The original JC 1 was based on a complementary differential J-FET input stage followed by two stages of selected push-pull MOSFETs, ultimately driving nine pairs of the most powerful complementary bipolar power transistors that were available in the early 2000s. Considered to be one of the foundational products of the American high-end renaissance, it introduced a circuit topology that many will point to as the basis for virtually all modern amplifiers. Even though at its original price of $6000 for a stereo pair, the JC 1 could never be considered a "budget" product in the truest sense of the word. Honestly, I cannot think of a pair of monoblocks that offer a view anywhere near this close to the top of the heap for anywhere near their asking price. It's not inconceivable that a nearly 20-year-old amplifier might need to have certain parts (such as electrolytic capacitors) replaced. I added the Parasound Halo A23 to boost the potential of my PSB Image towers and I am in love all over again. Founded in 1981, Parasound Products, Inc., is a privately-owned U.S. company that specializes in providing affordable audio components to the critical listener. Great amps for the money. Not so easy. And even with a price of $1895, making it the most expensive solid-state phonostage ever brought to market at that time, what many consider to be JC's magnum opus was still highly sought out. His layouts were as much art as engineering. Fundamental tonality and color from guitar, piano, violin, the human voice, et. If those companies have no choice other than to switch to using at least some surface-mount parts, then they would need to retract their previous assertions about the alleged inferiority of surface-mount technology. A detailed explanation of all the changes and improvements incorporated in the Halo JC 1+ can be found on the Parasound website. Parasound JC1 Monoblock Amplifiers Power Amps. At first the JC1s seemed to have a conservative bass, but turns out, it just was more detailed. As the JC 1+ operates in class-A up to 25W into 8 ohms when its bias is set to Normal, it runs hot. Linear Systems doesn't have that available market, so the prices are inevitably going to be much higher, both due to basic economics and the yield challenges. Today's JC 1+ offers 450 watts into 8 ohms, 850 watts into 4 ohms, and 1300 watts into 2 ohms! Midrange, while clearly not as utterly compelling as is rendered by today's benchmark-setting amplifiers such as the VAC Statement 450i iQ Integrated ($150,000) or the Statement 452iQ Musicblocs ($150,000/pr. The actuality was that, unlike many other amplifiers in this class, I was never drawn to, or even tempted to focus or speculate about any individual sonic attribute, and speaks volumes as to the success of their design and execution. It's also disconcerting to find out that Mr. Curl/Parasound decided to incorporate obsolete devices into a new/updated product offering. John saw this as the perfect opportunity to show what his designs could really deliver, as well as making a definitive statement as to how he felt he had been treated at Mark Levinson Audio Systems. In their eyes, that’s just a bad and rushed design. All material within this site is copyrighted and can not be reprinted or used in any form without our express written permission. ", While those are encouraging words, and seem to indicate that I'm doing the right things with component and cable selection as well as room set up, my system (every system? The amp's distortion is completely masked by the much greater speaker distortion. New to the Plus iteration is the use of FR-408 circuit board material, an R-core power transformer on the input stages, and extensively augmented input board shielding, all implemented to improve high-frequency performance and overall signal integrity. I've seen more than one case where the last-time-buy didn't last a lifetime. His first product, the TCP-1 phase-coherent electronic crossover, never really received the attention it deserved. The Parasound Halo JC 1+ power amplifier, in black or silver finish, will be available from authorized Parasound dealers in Q1, 2020, with a USA retail price of $8,495 each.. Actual time spent with the Parasound products in my own system (NC2250 and NC5250) and a friends system (Halo JC1 , A51, A21, ZoneMaster 650) 4. ), its midrange simply blusters with life while maintaining its refined detail, with remarkably full body and richness of harmonic bloom. This allowed for most of its output envelope, apart from the demand for large bass transients for example, to be contained within the class A operational mode, giving it a remarkably sweet and engaging sonic signature. Aesthetically, Parasound says the front panel not only matches the updated Halo family appearance, but also complements “the inner beauty” of the JC1+. Parasound JC1. Two 6 foot tall by 4 foot wide panels of Auralex Studiofoam Wedgies act as diffraction/absorption panels at the first side-wall reflection point for the speakers. Audiophiles of many years have remarked things like, "What more could you ask for," and "I've never heard a rig sound ANY BETTER than this. Amplifier Review Parasound JC3+ phono amplifier, a dual mono design Posted on 14th April 2016. The JC1 features one of the largest power transformers I’ve seen in recent memory and is largely the reason for the JC1’s 60-plus pounds of weight. It would be natural to compare the Halo Jr. to the original JC 3 and more recently the updated Halo JC 3+. That's been the trend for a while. Parasound JC5 thoughts Since I had paired Parasound and KEF in previous systems with much success (JC1’s and Reference 3), I jumped at the chance to hear the new JC5 and the Blade 2’s together. £399.00. These amps are magnificent performers in nearly every regard. This means that in addition to delivering 1300 watts into 2Ω, it can also deliver 450 watts into 8Ω and 850 watts into 4Ω. In Australia that'll cost you a kidney a lung and left testicle. £195.00. Today's JC 1+ carries a retail of $8,495 each, a near doubling in price since the discontinuation just two years ago. I went with Emotiva because the equivalent amps I expected to get had increased so much in cost since I last was in the market. All other devices in that room (lights, printers, computers, etc.) First, hats off to Parasound for not bowing to convention and badging its new, hot-rodded version of the original JC 3 phonostage with the shop-worn cliché “Reference” or “Signature Edition.” And second, and more importantly, if you’re a current owner of the Parasound JC 3 phonostage, don’t panic. Features, Features, Features . First, the Parasound enables the full potential of these speakers to be reached. The 22,400uF is the figure for the input stage supply. I hope you don't take offense when I decline to respond further. That year, the system Bob was showing incorporated the CTC Blowtorch preamplifier ($12,500), Bob's own TG Audio Labs Digital System prototypes ($12,000) for source material, his own TG wiring throughout, and the very open, relaxed, and luminous, six-and-a-half-foot tall, SoundLab Millennium-1's ($16,240).
