Every part of a Clarus Cable is unique – there are no off-the-shelf components in the manufacturing. 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. It’s not ours. The JC 1+ power amplifier is truly an achievement to the highest degree. 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. The sound is exemplary. We don’t fix what isn’t broken. IMD at 5 Volts output into 8 Ohms was 0.0049%. Textures and details that are glossed over in the A21 as one fat note. 4,5, and 8 – James Ehnes, James Armstrong – Onyx – Released 4/24/2020. 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. They are similar to Crimson but have smaller conductors. RS: The manufacture of FETs is a totally different process than bi-polar devices. You can choose between a black chassis or silver. 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? It … 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. With the exception of hand-milled aluminum panel end caps and replacing the illuminated P logo with an embossed logo, the JC 1+ 4 rack space chassis is the same as the JC 1 chassis which was designed in 2001 and tooled in 2002. Actual time spent with the Parasound products in my own system (NC2250 and NC5250) and a friends system (Halo JC1 … The overall sound is warm, almost tube-like, which I find very, very pleasant. Perhaps lower output impedance only applies to the output stage output impedance. 2L is world-renown for superb quality digital recordings. My setup required the long cable for the right channel. Even at idle, the JC 1 puts out plenty of heat, so ample ventilation is critical. The Parasound JC 1+ Power Amplifiers are very high quality. The difference between the 2. It is worth reading cover to cover. 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. Positive reviews by both leading audio reviewers and customers alike 2. The biggest improvement would be to secure the future of serious audio. "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." Some were digitally remastered, and this is probably because the master analog tapes were in poor condition. The output stage supplies current, for which John Curl specifies bi-polar devices. RS: The manufacture of FETs is a totally different process than bi-polar devices. By ultra-high-end standards, $6000 is not a lot for a pair of monoblocks amplifiers, but it's a big enough step upmarket for Parasound that the new Halo moniker distinguishes the line from other Parasound products. In black or silver finish, the Halo JC 1+ will be available from authorized Parasound … This is largely because their harmonic characteristics tend to be even-ordered, emulating this characteristic of vacuum tubes. The Parasound Halo JC 5 certainly lives up to the buzz. I had thought that lower output impedance is best. Twenty Volts output into 8 Ohms (50 watts). At 4 Ohms, the number of peaks was increased by two on either side of the fundamentals. The arrangement allowed NAD to go into business with relatively little capital outlay and low overhead. THD+N vs. Power Output usually is tested only with a 1 kHz sine wave. So I asked John Curl and he called the brilliant microwave engineer in Silicon Valley with whom he co-invented Bybee Music Rails. There is also voltage sag that occurs with 120 VAC wall socket supplies during high current demand. He learned that “Class J” is for microwave frequencies in the gigahertz range. It has PE fiber as the core and thin copper foil wrapped spirally around the core using special non-typical machinery. 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. Music – Tidal – Julio Iglesias – Mexico – Released 5/8/2020. They had a very clean sound without harshness. Parasound … One camp expressed interest in expediting a JC 1 replacement that would abandon Class AB by abandoning an enormous linear power supply and whatever R&D time was required for a 6 month development time and vastly lower cost by simply using Pascal* X-PRO1 modules. While Richard Schram notes in a print interview from May of 2015 that the original Parasound Halo JC-1 amplifier … I own both this amplifiers and is A McIntosh Mc152 VS Parasound 2250v2. Good for life, I think. That would have produced induction (like a transformer coil). But that is realized primarily by people who have the means to spend vast amounts of money and are willing to live with the intrusion of very large speakers and bulky speaker wire, etc. Here is the cable attached to a Sonus faber Lilium speaker. The bass in this album is intense. Keep track of using the red banana plug for one side (either + or -) for both ends of the cable. Approaching our 40. 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. It has the Schola Sanctae Sunnivae Girls’ Choir from Trondheim, founded in 1992. In their eyes, that’s just a bad and rushed design. Parasound, builder of preamplifiers and power amplifiers, was started in 1981 by Richard Schram, in San Francisco, California.

This is as good an album as any for you to introduce yourself to his talent. 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. 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.
