The JC 1+ is even more impressive. "The Parasound JC 1+ Power Amplifiers are very high quality. This poses a real challenge to our supply chain management. by John E. Johnson, Jr. | Jun 5, 2020 | Product Review. Music – Tidal – Art Blakey & the Jazz Messengers – The Finest – Blue Note, Universal – Released 4/3/2020. At 83 pounds, the new JC 1+ is 30 percent heavier than the JC 1. San Francisco |  January 17, 2020 — For nearly two decades, the Parasound Halo JC 1 monoblock power amplifier, designed by the legendary John Curl, wasParasound’s flagship product, and the aspirational amplifier for thousands of audiophiles world-wide. RS:  I agree that we’ve reached a level that is truly superb. Music – Tidal – Beethoven Violin Sonatas Nos. It is a little more than 70 dB lower than the signal peaks. When it launched in 2003, the JC 1 sold at retail for $3,000 each and was considered one of the best values among the elite of high-end mono amplifiers in its day. RS: John Curl and I recently discussed this, and we are gathering information. There are harmonics of the B-A peak at 2 kHz, 3 kHz, and 5 kHz. Our well-regarded and popular NewClassic 200 Integrated amplifier uses a Pascal module and has received extensive critical acclaim. Press Esc to cancel. I found a, Note that such cables are for high-end products (amplifiers and speakers). You have asked some interesting questions. Usually, the speaker binding posts on the rear of the receivers and speakers will have red and black posts. So I asked John Curl and he called the brilliant microwave engineer in Silicon Valley with whom he co-invented Bybee Music Rails. Observable harmonics went out to 17, At 4 Ohms, distortion plus noise was still less than 0.01%. 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 … All of these special conductors then go through precision twisting machines before going through another extrusion line to add the outer jacket. RS: I can’t imagine it breaking out of its present niche. One-owner. Using 10 kHz and 4 Ohms, distortion was higher overall, and clipping was at 760 Watts. For more information, visit www.parasound.com or call 415-397-7100. Parasound JC 5 Halo Stereo Power Amplifier B-Stock Full Warranty A Chip Off the Old Monoblock Parasound's Halo JC 5 distills the essence of two Hal... View full details Original price $5,995.00 At 20 Volts, 8 Ohms, IMD increased to 0.0204%. Using 4 Ohms impedance at 20 Volts, there were nine side peaks on the right side, and they were higher. I didn’t want to have the left channel the same length (20 feet) which would have necessitated coiling it up behind the speaker. 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. They had a very clean sound without harshness. The sub-assemblies are then twisted together, or else held in fixtures in the case of flat cables, to provide the plus and minus conductors. The sound reflects its amazing design. The Parasound JC 1+ power amplifiers are up to the task here. Still insignificant. 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. It has enough power (450 watts RMS into 8 Ohms) to drive any speaker, and the parts quality is a statement on its own. THD+N vs. Power Output usually is tested only with a 1 kHz sine wave. Our business model is based on building products in which we invest heavily in R&D, with the expectation that they will remain in continuous production for many years. I decided that I would never use such cable again. The new amp boasts 24 Sanken 15A/230V output transistors compared to 18 — a 33 percent peak current increase, for music that truly soars. It’s not ours. Results 1 … I chose black. RS: I haven’t paid enough attention to video to have an informed opinion. In that time, Parasound has established itself as a quality manufacturer. 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). 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. Had I just seen the amplifiers with no preparatory information I would have figured the price to be at least … Clarus also has a lower priced line of cables called Aqua, which are about half the price of the Crimson. One leg is 8 feet long, and the other is 20 feet. (According to an online inflation … Silver color. Used gently. NEWS; EDITORIAL REVIEWS ... 40% off on Parasound Halo JC1's! “We couldn’t imagine how to improve it. Some were digitally remastered, and this is probably because the master analog tapes were in poor condition. At 4 Ohms. The frequency response is down 0.2 dB at 20 kHz, on spec. 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. Each part of the cable design including the connectors, breakouts, silicon tubing, and cabling required expensive tooling. (I bought it through Audiogon after the first owner changed his mind in the first … One of the special shapes is the spiral ribbon conductor. At $16,990 for a pair, they are not cheap, but this kind of quality never is. Performance. I measured the impedance of the 20 foot cable, and it was 35 mOhm (milli-ohms) at 1 kHz, which is very low. January […], The following is a press release issued by Cambridge Audio. 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 to be … So, this is an interesting new set of tests (THD+N vs. Power at different frequencies).
