parasound jc1+ review



Here is a photo of the inside of the chassis: Look how big the heat sinks are. The rear panel has myriad selections, inputs, and outputs. These amps are magnificent performers in nearly every regard," raves Greg Weaver in his review for Positive Feedbackonline magazine. 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. The impedance is 6/20 that of the 20 foot cable, which is 10.5 mOhm (10.5 thousandths of an Ohm). When Parasound released their JC 1 monoblock power amplifier in 2002, the A/V world was very impressed. Power supply capacitance increased from 132,000 µF to 198,000 µF (that is 1/5. Design The JC 1 is a brawny brute weighing 64 lbs. The difference between the 2nd ordered harmonic and the 3rd was reduced to about 5 dB. I used a Clarus Concerto Power Conditioner for the computer, OPPO UDP-205, and Pass Labs Xs Preamplifier. Music – The Beauty that Still Remains – 2L Norway – 2020. 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 has the Schola Sanctae Sunnivae Girls’ Choir from Trondheim, founded in 1992. A Scherzo is a light composition, frequently the third movement of a symphony, sonata, or string quartet; also, in the Baroque era (c. 1600–c. So, it is not just the ability to drive any speaker on the planet. Distortion plus noise was still quite low. It is a decades-old lament that our industry hasn’t found a way to make superb musical reproduction equipment compelling for young people. For you youngsters, John Curl has been designing high-end gear since the early 1970s, including the classic Mark Levinson JC-2 and Dennesen JC-80 preamplifiers, the much-revered Vendetta phono preamplifier, and lots of electronic gear for the Grateful Dead. Our frugality enables Parasound to purchase large quantities of superior parts, unmatched by present parts, that were discontinued long ago. They celebrate their 40th year, next year, in 2021. We don’t fix what isn’t broken. RS: I haven’t paid enough attention to video to have an informed opinion. 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 … Parasound's 7.5-channel surround controller has finally landed.

The JC 1+ is even more powerful, at 450 watts. It can also … Although a home-made cable like this will have higher impedance than the Clarus Crimson or other high-end cables, they will be fine for mass market products. I believe the primary purpose for developing and marketing an amplifier is to honor its customers in every respect the money will follow. 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. That is very important to a relaxing music listening experience. by John E. Johnson, Jr. | Jun 5, 2020 | Product Review. I would suggest that you get the cables with spade connectors for a more permanent attachment. Amplifiers are out there that cost a quarter of a million dollars. "...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. 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? At 4 Ohms, the number of peaks was increased by two on either side of the fundamentals. We anticipated its continuing growth and developed two new phono preamps in the past two years. They can be switched out of the signal path when not needed, giving a slightly clearer sound. The JC 1+ embodies our highest achievement of value engineering and my greatest sense of accomplishment. Excellent condition. "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. 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. Class G and H refer primarily to an amplifier’s power supply topology. 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 bass in this album is intense. You might recall the stylish floor-standing Revox tape deck announced in 2017, then cancelled because it wouldn’t make economic sense for them. Amplifier sale includes (10) Synergistic Research BLACK fuses, installed and original factory fuses. Will Class D, G, H, and J amplifiers become the norm in receivers and power amplifiers compared to Class A and A/B? In their eyes, that’s just a bad and rushed design. Their characteristics are undesirable for high quality audio frequency amplification. 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. A “hidden cost” of continuing to build high quality Class AB amplifiers is the paucity of component parts. I felt the “keep it simpler” approach was inconsistent with our values and not sufficiently forward looking. 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. Curl describes the JC 1 as an outgrowth of his Parasound HCA-2200 from 1997. ... the JC1 is a definite step up. The other end was connected to the Parasound JC 1+ power amplifier. So, that is what I did. Parasound has long been admired for their preamplifiers and power amplifiers. All the components are made in their own facility using custom-designed extruding machines. That is normal. Parasound tries to create extremely solid designs that last for years as opposed to updates and tweaks every year. Every year more audio-grade component parts are discontinued because the volumes are too small and inconvenient for component parts manufacturers. Thirty years ago, the upstart audio company NAD revolutionized the manufacturing of consumer-electronics components by "internationalizing" the process. Looking at the complexity of these cables, I can see why they are expensive. This 20 foot cable by itself is $4,000 retail price. I recently tried some generic speaker cable. In black or silver finish, the Halo JC 1+ will be available from authorized Parasound … 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. That, I think, is because analog tape often had a bass bump between 50 Hz and 100 Hz. It takes the … We can’t remember the last time we reviewed a product such as this with bass and treble controls. 5 fuses/amplier. Now that 8K flat panel TVs are here, will they be a passing fad or will they become the norm, which includes significant content? RS: John Curl and I recently discussed this, and we are gathering information. My answers are below, in red. Again, the Parasound JC 1+ amplifiers distinguished themselves. The JC 1 was powerful, at 400 watts RMS into 8 Ohms. The 5-to-1 ratio of cost to retail price that is the norm in the audio industry suggests that the "raw" cost of the JC 1 is about $600—a number almost impossible to believe, given the superb build quality and sheer heft of this powerhouse monoblock. Some will survive until the start-up money runs out. Parasound JC-1 power amplifiers. 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. In the case of the bi-wire cables, all four sets of conductors go through an extrusion line to add the final outer jacket. The JC 1 has much larger heatsinks, twice the power supply, better internal componentry and layout, and its range of operation in class-A has been extended to 25W, which should be enough to keep it from class-AB operation on all but the most demanding musical passages.

Distortion plus noise was still quite low. 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. It will allow very quiet passages and very loud passages as well, without having to change the volume control. "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." If you have relatively inexpensive mass-market receiver and speakers, then such cables would not be appropriate. 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). Clarus also has a lower priced line of cables called Aqua, which are about half the price of the Crimson. In the evaluation of costs, it is also necessary to consider the thousands of hours of R&D involved to perfect the final cable geometry as well as the initial tooling costs. When it was designed in 2000, and for many subsequent years, it was the best power amp we could build while staying within the practical boundaries that define all of our products: “We believe most Parasound customers aren’t independently wealthy.”  Our unwavering commitment to Value Engineering continues to differentiate Parasound from other brands. Distortion plus noise was 0.0066%. Yes. Other companies have since copied this ingenious business model, and, as transportation and communication have improved, doing so has become easier and more efficient. 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. Additionally, Parasound's A21 just won an … We like and respect Pascal’s products and staff. Fortunately, the power amp had a protection circuit. Most of the tracks were remastered in 1998, 1999, and 2005. THD+N vs. This album has Lee Morgan on trumpet, Benny Golson on tenor sax, Bobby Timmons on piano, and Art Blakey on drums. Still insignificant. I continue to be amazed at how good the tracks from 60 year-old analog tapes sound. 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. This test uses 1 kHz. 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-Channel … At 20 Volts, 8 Ohms, IMD increased to 0.0204%. 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. It is because there are many notes that are being played at the same time, perhaps 10 because there are 10 fingers on two hands. It clips (1%) at 450 Watts RMS. It has enough power (450 watts RMS into 8 Ohms) to drive any speaker, and the parts quality is a statement on its own. They are worth the price. As such, Clarus Cables represent an excellent value for consumers wishing to improve their system’s performance.
