Yes. Among the upgraded parts used in the JC 1 are a 10-amp toroidal transformer enclosed in a steel canister filled with epoxy resin, Sanken output transistors, Harris hyperfast soft-recovery diodes, Nichicon Muse DC and local bypass capacitors, Nichicon Great Supply raw DC capacitors (for a total of 132,000µF capacitance), and Vampire continuous-cast copper wire and gold-plated OFC RCA jacks. Right on spec. ... is to review … Will the latest transistor technology (stacked Nanosheet FETs) provide audible differences from conventional bipolar and Mosfet/JFet technology? RS: The manufacture of FETs is a totally different process than bi-polar devices. by John E. Johnson, Jr. | Jun 5, 2020 | Product Review. Can you clarify? The Parasound Halo JC 1+ power amplifier, in black or silver finish, will be available from authorized Parasound … But Pascal’s rating of 1500w 8 ohms, 2500w 4 ohms and only 600w 2 ohms revealed a very different objective. It does show that if you listen to music pretty loud with a 4 Ohm speaker, the power limit from the amplifier will decrease as the amplifier heats up. It’s not ours. Consider Parasound's Halo JC 1 monoblock power amplifier, designed by legendary engineer John Curl and originally reviewed by Michael Fremer in February 2003. Anyway, I am convinced that it is worth the high price to get something that is built for an audiophile system in every stage of the signal path, including the cables. Next, a braiding machine braids the outer woven jacket onto the cable. PARASOUND JC 1+ POWER AMPLIFIER SPECIFICATIONS. Here is the choir with the recording setup in a cathedral. While Richard Schram notes in a print interview from May of 2015 that the original Parasound Halo JC-1 amplifier … Toward the end of this review, I received the new Parasound Halo P6 preamp that will solve this woe. So, that is what I did. This poses a real challenge to our supply chain management. In fact, the JC 1 is certified THX Ultra2—which means it meets certain amplifier standards set by THX for home theater. Looking at the complexity of these cables, I can see why they are expensive. At 20 Volts, 8 Ohms, IMD increased to 0.0204%. We will see how various amplifiers perform with these tests as time goes along. Integrated amplifiers exist with … "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. Familiarity with the product and manufacturer 3. So I asked John Curl and he called the brilliant microwave engineer in Silicon Valley with whom he co-invented Bybee Music Rails. It takes the … Frequency, 5 Volts and 20 Volts output, is shown below, at 8 Ohms load. The JC 1+ power amplifier monoblock is their latest achievement, and it truly is an achievement to the highest … What made you decide to design a power amplifier with no compromises of any kind? There are harmonics of the B-A peak at 2 kHz, 3 kHz, and 5 kHz. Parasound’s Halo JC 1+ has a fast-start bias circuit that enables it to sound its best within minutes after turn-on. Piano is another difficult instrument to reproduce, but not because of a prevalence of distortion. While it may always get second billing in the parade of human emotions, don't forget about anticipation's potent influence. Parasound Halo A23 Stereo Amplifier Review In light of our slow shift toward two channel audio (no, we are not abandoning personal audio), I decided it would be a good idea to start with something basic, like a stereo amplifier. I own both this amplifiers and is A McIntosh Mc152 VS Parasound 2250v2. Our frugality enables Parasound to purchase large quantities of superior parts, unmatched by present parts, that were discontinued long ago. FETs are, in fact, high impedance devices which are superior for voltage amplification. There are also facilities for automatic turn-on (by an audio signal or an external trigger voltage), which can be daisy-chained to turn on other components. One of the most important of the Parasound’s capabilities is in dynamics. The JC 1 took up … Separate power supplies for the input, driver, and output sections are said to make the JC 1 totally immune from AC-line voltage fluctuations. Parasound has long been admired for their preamplifiers and power amplifiers. There is no power conditioner out there that will handle the 2,600 watt potential of the two JC 1+ power amps, especially when the computer, universal player, and preamplifier are also plugged into it. Distortion goes down at high frequencies (above 40 kHz) because the number of harmonics that the amplifier can pass is also reduced. I believe the primary purpose for developing and marketing an amplifier is to honor its customers in every respect the money will follow. The JC 1+ embodies our highest achievement of value engineering and my greatest sense of accomplishment. We can’t remember the last time we reviewed a product such as this with bass and treble controls. Textures and details that are glossed over in the A21 as one fat note. Many manufacturers don’t seem to care about this, or they aren’t aware that they are operating on borrowed time and are content with their present business model. It clips (1%) at 450 Watts RMS. The impedance is 6/20 that of the 20 foot cable, which is 10.5 mOhm (10.5 thousandths of an Ohm). The Parasound Halo JC 1—a powerful, sophisticated premium product—was designed by a team headed by audio legend John Curl, and built for Parasound by a factory in Taiwan. Class G and H refer primarily to an amplifier’s power supply topology. The B-A peak at 1 kHz, 20 Volts, 4 Ohms, 19 kHz and 20 kHz sine waves. "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 aski… Thompson engineered the boards, Crump chose the parts and "voiced" the finished product. This is evident by the … For audio systems where the source and amplifier stack are in between the speakers, you would probably be using two of the 6 foot cables, at about $4,000 for the pair. I imagine there are new capacitors that sound as good, but I don’t blame Parasound with sticking to what works for them. Will Class D, G, H, and J amplifiers become the norm in receivers and power amplifiers compared to Class A and A/B? Since the core of these amps are the same how does one brand differentiate its amplifiers from another brand’s amplifiers using the same Class D module? Thirty years ago, the upstart audio company NAD revolutionized the manufacturing of consumer-electronics components by "internationalizing" the process. Amplifier sale includes (10) Synergistic Research BLACK fuses, installed and original factory fuses. review of the sound of various capacitors, https://www.monoprice.com/product?p_id=2747, https://www.monoprice.com/product?p_id=9436, https://www.amazon.com/Insulated-U-Type-Connector-Electrical-Terminal/dp/B07PG1NCQZ/ref=sr_1_18?dchild=1&keywords=spade+connectors&qid=1589736054&sr=8-18, https://www.audioadvisor.com/prodinfo.asp?number=AQT8NF&opt=1176|1189|1196|1201, https://www.audioadvisor.com/prodinfo.asp?number=KK4TC&opt=6440|392|398|404. Design The JC 1 is a brawny brute weighing 64 lbs. The disc is dedicated to Anne Frank, the 16 year old Jewish girl who was born in Frankfurt, Germany in 1929 and died in the Bergen-Belsen concentration camp in Germany in 1945. And, I don’t have to worry about cheap cables shorting out my power amplifiers that cost tens of thousands of dollars. Music – Tidal – Chopin Impromptus and Scherzos – Mao Fujita – Piano – Naxos – Released 10/16/2019. And despite what the purists say, on occasion, for example when playing a poorly engineered recording, they can be useful. Approaching our 40th anniversary, Parasound proves this ideal. Every year more audio-grade component parts are discontinued because the volumes are too small and inconvenient for component parts manufacturers. There is also voltage sag that occurs with 120 VAC wall socket supplies during high current demand. Using 10 kHz and 4 Ohms, distortion was higher overall, and clipping was at 760 Watts. Here is their answer: The patented design and construction of Clarus Cables are unique requiring sophisticated engineering and manufacturing equipment. The arrangement allowed NAD to go into business with relatively little capital outlay and low overhead. Art Blakey & the Jazz Messengers were a jazz combo from the classic jazz period of the mid 20th century. 1750), a light vocal or instrumental piece (e.g., the Scherzi musicali of Claudio Monteverdi, 1607), and, in the 19th century, an independent orchestral composition (https://www.britannica.com/art/scherzo). I haven't studied San Francisco-based Parasound Products' business or its books, but the NAD model has clearly been an influence on Parasound, which was founded in 1982. The sound is exemplary. "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." At 4 Ohms, the number of peaks was increased by two on either side of the fundamentals. Right on spec. We like and respect Pascal’s products and staff. The JC1 comes standard with rear-mounted rack handles, as well as a full rack-mounting kit, and features Parasound… Amplifier Reviews, Audio Reviews, Equipment Reviews Published On: December 29, 2009 Parasound Halo JC 1 Monaural Amplifier Reviewed As far as audiophile amp designers go - John Curl … Parasound did a thorough job in writing the manual for the A21+. The overall sound is warm, almost tube-like, which I find very, very pleasant. Music – Tidal – Art Blakey & the Jazz Messengers – The Finest – Blue Note, Universal – Released 4/3/2020. I had thought that lower output impedance is best. He learned that “Class J” is for microwave frequencies in the gigahertz range. The output stage supplies current, for which John Curl specifies bi-polar devices. Parasound's new $2995 JC3+ is a significantly upgraded version of the already high performance original JC3 phono preamplifier, though outwardly it looks identical to the handsome original. All of these musicians were stars in their own right. B-Stock gives audiophile enthusiasts the opportunity to purchase Parasound products at a discounted price. The difference between the 2nd ordered harmonic and the 3rd was reduced to about 5 dB. That, I think, is because analog tape often had a bass bump between 50 Hz and 100 Hz. One leg is 8 feet long, and the other is 20 feet. It is worth reading cover to cover. Couldn't help but notice the recent sale Audio Advisor had on the black color edition of the Parasound JC-2 preamps. My position is different. Music – Tidal – Art Blakey & the Jazz Messengers –, Art Blakey & the Jazz Messengers were a jazz combo from the classic jazz period of the mid 20, Parasound states that they use Nichicon Gold Tune capacitors for the power supply, and that although these capacitors are no longer generally available, Parasound has an exclusive contract with Nichicon to continue supplying these caps to them. Usually, the speaker binding posts on the rear of the receivers and speakers will have red and black posts. Again, the Parasound JC 1+ amplifiers distinguished themselves. If you want something that is ready to go (for mass market receivers), and not generic, then consider something like these (https://www.audioadvisor.com/prodinfo.asp?number=AQT8NF&opt=1176|1189|1196|1201), or these (https://www.audioadvisor.com/prodinfo.asp?number=KK4TC&opt=6440|392|398|404) for the front left and right channels. There are thousands of Blu-ray discs (2K), but just a few hundred 4K movie discs even though 4K has been here for several years, so 4K has had only limited success. I know, I know, that is a lot of money for a speaker cable, but it sure is not going to short out and pop my power amplifier protection circuit. It’s not the same as purchasing transistors, capacitors, resistors, and other parts that are already manufactured.

According to Crump, the JC 1 grew out of a CTC-modified Parasound HCA-3500 called the CTC BBQ, which was demoed at the 2001 Consumer Electronics Show. The rear panel has myriad selections, inputs, and outputs. If you have relatively inexpensive mass-market receiver and speakers, then such cables would not be appropriate. Instead of physically making products, NAD hired a project team in one location to design a product that was then built at a sub-contracted factory located elsewhere. The sound is exemplary and reflects its … The JC 1+ power amplifier monoblock is their latest achievement, and it truly is an achievement to the highest degree. Music – Tidal – Beethoven Violin Sonatas Nos. They are worth the price. It has enough power (450 watts RMS into 8 Ohms) to drive any speaker, and the parts quality is a statement on its own. It is a little more than 70 dB lower than the signal peaks. No one felt they could ever be, Parasound, builder of preamplifiers and power amplifiers, was started in 1981 by Richard Schram, in San Francisco, California. Products that are primarily silicon-based are, by definition, subject to constant changes because the enormous manufacturers of these parts must continually innovate with new features to justify higher prices and annual reports that will satisfy their shareholders. This part of my job brings me enormous pleasure and satisfaction. Still insignificant. Distortion plus noise was still quite low. Parasound's 7.5-channel surround controller has finally landed. A switch on the rear allows users to drop class-A operation down to 10W for placement in tight spaces. Distortion plus noise was 0.0066%. I am concerned about what I call the “over-democratization” of Class D. Anyone can purchase an excellent Class D module, slap on their “special” input stage and bring an amp to market. This makes for a complex waveform. This brought out some deep “presence” that is appealing. It can also … I use banana plugs because I have to make changes easily when I am reviewing speakers. Other companies have since copied this ingenious business model, and, as transportation and communication have improved, doing so has become easier and more efficient. Actual time spent with the Parasound products in my own system (NC2250 and NC5250) and a friends system (Halo JC1 … THD+N vs. Power Output, at 8 Ohms, is shown below. 1. I used a Clarus Concerto Power Conditioner for the computer, OPPO UDP-205, and Pass Labs Xs Preamplifier. Toshiba JFETs for the input stage, Sanken bipolar transistors for the output stage, Nichicon Gold Tune power supply capacitors totaling 198,000 µF, a 30 pound 2,100 watt power supply transformer, a special circuit board substrate that delivers better propagation of high frequencies compared to Delrin, etc. Proof of Performance for the Parasound has been verified. The list goes on and on. The JC 1 was powerful, at 400 watts RMS into 8 Ohms. Clarus also has a lower priced line of cables called Aqua, which are about half the price of the Crimson. RS: The JC 1 was warmly received and enjoyed a very long and illustrious product life. At 4 Ohms, distortion was a tiny bit higher. Twenty Volts output into 8 Ohms (50 watts). I'm sure it's possible to build a quieter preamplifier/amplifier (Parasound also makes the $11,000 JC2/JC1/JC1), but I'm not sure the improvement would be audible. This is largely because their harmonic characteristics tend to be even-ordered, emulating this characteristic of vacuum tubes. Distortion is a few hundredths of a percent higher. This new disc has their typical array of resolutions and formats, including 24/192 DTS HD MA, Dolby Atmos 7.0.4 48 kHz, Auro-3D 96 kHz, SACD, and 2-channel 24/192 PCM. In this case, I would recommend getting a 50 foot or 100 foot roll of 12 gauge stranded speaker cable from Monoprice (https://www.monoprice.com/product?p_id=2747) and some banana plugs (https://www.monoprice.com/product?p_id=9436) or spade connectors (https://www.amazon.com/Insulated-U-Type-Connector-Electrical-Terminal/dp/B07PG1NCQZ/ref=sr_1_18?dchild=1&keywords=spade+connectors&qid=1589736054&sr=8-18) (you will have to solder spade lugs to the cable). They had a very clean sound without harshness. At 4 Ohms, distortion plus noise was still less than 0.01%. That is normal. 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. RS: The manufacture of FETs is a totally different process than bi-polar devices. This is as good an album as any for you to introduce yourself to his talent. No one felt they could ever be more impressed with one of their amplifiers, but the release of the JC 1+ monoblock changed that thinking. ALL B-stock items are all professionally inspected by Parasound technicians and, most importantly, ALL B-Stock products contain the exact same FULL Parasound … You will need a wire stripper, and in the case of the spade lugs, a soldering iron with some solder. The B-A peak with 8 Ohms impedance is 3 dB lower than at 4 Ohms (about 73 dB lower than the signal peaks). THD+N vs. Power Output usually is tested only with a 1 kHz sine wave. So, it is not just the ability to drive any speaker on the planet. We don’t fix what isn’t broken. RS: I don’t have sufficient familiarity to answer this since we discontinued production of our Halo C 1 and C 2 surround processors. The JC 1+ is even more powerful, at 450 watts. Note that such cables are for high-end products (amplifiers and speakers). While no audiophile would want to listen to this or any solid-state amp from a cold start, the JC 1 has been designed for home-theater use—five of these beasts left running continuously could generate an enormous amount of heat and large electric bills. It has the Schola Sanctae Sunnivae Girls’ Choir from Trondheim, founded in 1992. You can choose between a black chassis or silver. I believe the primary purpose for developing and marketing an amplifier is to honor its customers in every respect the money will follow. We remain committed to vinyl. That would have produced induction (like a transformer coil). This test uses 1 kHz. At first the JC1s seemed to have a conservative bass, but turns out, it just was more detailed. Is there any new surround sound format coming? THD+N vs. Fortunately, the power amp had a protection circuit. It is a decades-old lament that our industry hasn’t found a way to make superb musical reproduction equipment compelling for young people. RS: John Curl and I recently discussed this, and we are gathering information. Its very high power (450 watts into 8 ohms) delivers a tremendous dynamic range. Music – Tidal – Julio Iglesias – Mexico – Released 5/8/2020. Normally a $4.5K price offered at $3K. Parasound has long been admired for their preamplifiers and power amplifiers. Some were digitally remastered, and this is probably because the master analog tapes were in poor condition. Using 19 kHz and 20 kHz sine waves at 5 Volts into 8 Ohms, there were two visible peaks on either side of the fundamentals. The new Parasound … When, in 2014, Curl identified new opportunities for improvements that didn’t exist when the JC 1 was designed years ago, I considered it my responsibility to again build the best amplifier I could. A bias level selector switch enables cooler operation, with virtually no … RS: I can’t imagine it breaking out of its present niche. The difference between the 2. I recently tried some generic speaker cable. Violins are difficult instruments to reproduce because they are mostly very high frequencies, and this is where a lot of distortion can occur. It has to be verified. In this case, I wanted to be able to discern individual voices of the girls, among the background music. We will look into any emerging technology that has the potential of improving performance and offering a tangible benefit to listeners. A “hidden cost” of continuing to build high quality Class AB amplifiers is the paucity of component parts. Now that 8K flat panel TVs are here, will they be a passing fad or will they become the norm, which includes significant content? It clips (1%) at 450 Watts RMS. RS: I am not familiar with Class J and found no mention in Wikipedia. Observable harmonics went out to 17th order. RS: I haven’t paid enough attention to video to have an informed opinion. Track 21 is particularly gorgeous. Our well-regarded and popular NewClassic 200 Integrated amplifier uses a Pascal module and has received extensive critical acclaim. The raw wire used for making speaker, audio, and power cables are made with conductors that are extruded into special shapes using the highest grade of ultra-pure copper available. We had some lively discussions within Parasound about this topic in the early stage of the JC 1+ development. THD+N vs. Power Output, at 8 Ohms, is shown below. Even though our NewClassic power amplifiers are superb examples of Class G, we mention only their Class AB audio circuit topology to avoid confusion. My setup required the long cable for the right channel. Positive reviews by both leading audio reviewers and customers alike 2. The front panel design not only matches the updated Halo family appearance, but also complements the inner beauty of the JC1+. Every part of a Clarus Cable is unique – there are no off-the-shelf components in the manufacturing. IMD at 5 Volts output into 8 Ohms was 0.0049%. Increasing the output to 20 Volts produced seven peaks on either side, at 8 Ohms. Rear-panel fittings include balanced and single-ended inputs, two sets of five-way binding-post outputs, a ground "lift" switch for when there are hum problems, and a bias-level switch allowing for reduced bias current, and thus cooler operation if needed. 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. I didn’t want to have the left channel the same length (20 feet) which would have necessitated coiling it up behind the speaker. They celebrate their 40, The JC 1 was powerful, at 400 watts RMS into 8 Ohms. The Parasound JC 1+ power amplifiers are up to the task here. Most of the tracks were remastered in 1998, 1999, and 2005. Here is a photo of the inside of the chassis: Look how big the heat sinks are. Protection for both amplifier and loudspeaker is also provided by a gold-plated relay, and by current-sensing transistors that will open the relay if the current draw exceeds a predetermined amount, whether due to the impedance dropping below 1 ohm or a short at the speaker terminals. Dynamic, clarity, detail. The power supply transformer is now 2.1 kVA (2,100 watts), which is important when you consider that, at 2 Ohms, the JC 1+ can deliver 1,200 watts (if you have them both plugged into the same 20 ampere 120 V AC circuit, it may trigger the circuit breaker – now that’s my kind of power). That is very important to a relaxing music listening experience. For instance, many other high-end cables, which cost much less than Clarus to manufacture, can cost the consumer many multiples of Clarus yet not sound as good. There are is no economy of scale for tape recordings, rebuilt tape decks are hard to find and prohibitively expensive and there isn’t sufficient possibility of a return on investment for any audio manufacturer to design and manufacture tape decks. Curl describes the JC 1 as an outgrowth of his Parasound HCA-2200 from 1997. I found a, Note that such cables are for high-end products (amplifiers and speakers). I listened to a pair of the Parasound JC 1+ power amplifiers with a computer (PC) delivering Tidal music streaming via USB input to an OPPO UDP-205 Universal Player, a hard drive connected to the UDP-205 with my entire digital music collection stored on it, VPI-HR-X Turntable with Sumiko Palo Santos MC Phono Cartridge, Manley Labs Steelhead Phono Preamplifier, Pass Labs Xs Preamplifier, Sonus faber Lilium Speakers, Wireworld XLR cables, and Clarus Crimson speaker cables. At 1 kHz and 5 Volts into 8 Ohms. They are similar to Crimson but have smaller conductors.
