parasound jc1 review

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! In addition, the JC 1+ uses a pair of Bybee Music Rails, which are patented active, high-frequency noise filters. $$$$$$$$$$. I don't want to get too far off into the weeds here; you can readily research John's extensive and incredible career. Parasound Halo JC2 BP Two Channel Preamplifier. The output / power supply circuit board copper traces are doubled in thickness, and all internal audio signal path connectors are gold-plated. Price and availability. Tested at £2700. 26 watching. Power to components in the listening room is fully dedicated, with a pair of 20 amp runs for amplification, and another pair of 15 amp runs for all sources. Someday maybe I will own pair of the the JC1 + :) .. There just isn't the ready availability of film caps in the varieties found with through hole components. That characterization seems a tad extreme. Parasound has chosen to take a staple core product that has remained an exceptional value for over fifteen years, the Halo A21 amplifier, and re-spin it into the Halo A21+. • The new amplifier's printed circuit boards were designed by Carl Thompson, who was responsible for the boards in John Curl's Vendetta Research phono stage, as well as for the JC 1 and other Parasound products. or Best Offer. This amplifier needs to be well-ventilated, though if space is at a premium the output-stage bias can be lowered with the rear-panel switch, which reduces the class-A power to 10W into 8 ohms. 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. At least in the JFET world relevant to this discussion, much of their activity has been to clone the Toshiba designs. No other amp delivered as much musical enjoyment as the JC1s with either speaker. Not so easy. See www.stereophile.com/content/music-round-47-page-3. 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. Richard Schram says that although the Gold Tune capacitors were discontinued years ago, Nichicon continues to manufacture them exclusively for Parasound. Whether one would ever feel the need for such capacity is open to discussion, for the Halo JC5 is hardly short of power or dynamic ability in its standard stereo guise, as one might expect of an amplifier based on the John Curl-designed JC1 monoblock power amps. 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. 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’s easy to see why this Parasound has its set of loyal followers. Add to Compare . 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. His layouts were as much art as engineering. At first look the Parasound Halo A 51 is an appealing and robust amplifier accented by brushed metal finish. When I discussed the subject with the late Charley Hansen some years ago, the problem is that there weren't any replacement parts. That mono amp was awarded by Stereophile as Power Amplifier of the Year in 2003 and has honored it as a ‘Class A Recommended Component’ Many audio companies have already switched to surface mount semiconductors where the package is available. "Parasound has chosen to take a staple core product that has remained an exceptional value for over fifteen years, the Halo A21 amplifier, and re-spin it into the Halo A21+," reports Michael Zisserson at positive-feedback.com. Highs are so much more detailed without being annoying. Review after review, award after award seems to naturally follow a company who has put value without compromise first as defined by the very products they make. I wonder how different a pair of JC 1+ would sound in my current system; anyway, Well done, Mr. Curl is all I want to say as well for delivering the JC 5 - simply a most fantastic amplifier. Dell Optiplex 990 Windows 10 computer (core i5, 12 GB RAM, 256GB SSD) dedicated as a music server running JRiver Media Center 26, 64-Bit, Roon, and Fidelizer Pro v8.5. Parasound Halo JC 1 Monoblock Amplifier High value at a low(ish) price! John Atkinson 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. So look out for used cheap ones on the US … Fresh from their packing boxes and replacing my reference Audionet MAX monoblocks, even though they exhibited an overall slightly cooler tone and came down just a tad on the analytical side of natural, they did offer surprisingly good texture and spatial presentation. Positive reviews by both leading audio reviewers and customers alike 2. in what engineering realm does "no-longer-manufactured" mean "obsolete" ??? 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. Those early Krells could be a touch grainy-sounding in the treble, but the Halo JC 1+'s high frequencies were smooth and clean. Their ability to put out the first 10 or 25 watts pure class A makes them very resolving and natural sounding. https://www.analog.com/cpsearch/crossreferencesearch.aspx Linear Systems has really done yeoman's work in providing JFETs for specialized industries. ... totally stymied if a favorite component becomes "unobtanium"? I've seen more than one case where the last-time-buy didn't last a lifetime. This is especially true for P-channel devices, which are harder to make with low noise properties. Stealth Śakra V12, Stealth Śakra, Stealth Indra, Stealth Nanofiber, Stealth PGS, Stealth Helios phono cable, Audience frontRow single-ended and Balanced Interconnects, Furutech AG-16 R4 Silver-plated (Alpha) OCC Phono Cable, Audience Au24-SX (single-ended and balanced). :-) .......... Regrettably, I haven't had the opportunity to hear the JC 1+. Founded in 1981, Parasound Products, Inc., is a privately-owned U.S. company that specializes in providing affordable audio components to the critical listener. UK Edition. I had the pleasure of getting to know Bob through our annual visits at CES.

My initial impressions reminded me of the first time I heard a Krell class-A amplifier, in the early 1980s: low-frequency authority combined with superbly precise stereo imaging and a deep, stable soundstage. The Parasound Halo JC 5 certainly lives up to the buzz. are on an entirely separate, isolated circuit. ), or the Audionet Heisenberg's ($105,000/pr. Why do you think so many great/legendary amp designer's stockpile these JFETs (and other extra-ordinary parts)? As surprisingly exceptional and rewarding as its bass performance proved to be, particularly in this class, midrange performance was stunningly good as well. 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. According to Parasound’s Richard Schram, the original JC3’s design began as a phono preamp retrofit for the JC2 line stage with separate small circuit boards for each channel. I have had a few Parasound products over the years and currently own a P6 paired with a JC 5 power amp. I await them eagerly. Internal differences Great amps for the money. I can only imagine the new model must be exceptional. ... to the function of your design, or might PPS type capacitors - available in SMT for from WIMA and Panasonic, to name two - be satisfactory? product knowledge and to leverage their general audio experience, are simply wonderful. 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. Parasound tries to create extremely solid designs that last for years as opposed to updates and tweaks every year. https://cdn.motor1.com/images/mgl/A80qL/s1/2014-lamborghini-veneno-roads...

The prime listening area is centered roughly 10' back from the plane of the tweeters. On the Vimbergs powered by the Parasounds, this atmospheric track sounded way better than my almost-four-decades-old memory would have predicted. So, companies are then left with the choice of sonic compromise or to use mixed manufacturing technologies. There is a reason, after all, that KEF has often partnered with Parasound to highlight their speakers at audio shows throughout the world! In order to be able to use my PS Audio DirectStream D/A processor's volume control set sufficiently high so that its resolution would be preserved, I set the gain switches of the JC 1+ monoblocks to Low.

That's where the money is. Audio Dharma Cable Cooker 2.5 EFS. The availability of surface-mount film capacitors is ... bridged AHB2s would also be a very helpful comp, Great rap JA for a great amp, you get the good ones to review. It would be natural to compare the Halo Jr. to the original JC 3 and more recently the updated Halo JC 3+. However, unlike most coveted pieces of audiophilia, the JC1 was hugely affordable at $6,000 per pair, which meant that many audiophiles could actually own a piece of audio history, as opposed to just reading about it. While the JC 1 driver was a single-stage circuit, for the JC 1+, John Curl designed a two-stage, cascode driver that would have some of the favorable attributes of vacuum tubes. 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. :-) ....... ... slit-foil type electrolytic capacitors for quite some time. Not if Class-D and the environment has anything to do with it. In the days of CRT-type HDTV sets, Sanyo and Panasonic produced high-voltage transistors, with very low collector output capacitance, that were well suited for use in the driver stage of an audio power amp. :-). Maybe that trend is spreading into the solid-state "realm"? After 16 years of legendary reviews from their JC1 amplifier, Parasound has finally given consumers exactly what they want: Two top-of-the-line Halo JC 1 monoblock power amplifiers integrated into a single chassis that is the same size as one JC 1.
