    MY TAKE:
     

    For more than twenty years Parasound has been a name synonymous with unequaled value. Their electronics are respected for both performance and reliability, and compete with significantly more expensive products. Modestly priced, previous offerings have changed common perception about the level of performance that can be achieved at the price point.

    With the introduction of the Halo line, Parasound looks to bring the same level of value and performance to a more upscale market. The ambitious Halo range spans the gamut from state of the art home theater offerings to high end two-channel audio.

    For a number of years, the legendary John Curl has worked with Parasound as a consultant. His input has greatly influenced their products and is one of reasons for the praise they’ve received from the audiophile community. Several seasons ago Parasound again enlisted the services of Mr. Curl and his team, CTC Builders, to design the highest-quality power amplifier ever made. The result is the JC 1, manufactured exclusively by Parasound.

    The JC 1 is among the most transparent, dynamic, and sonically neutral solid-state amplifiers available. Its design sophistication, quality of parts and superb construction make the JC 1 and exceptional value.

    REVIEWS:

    Stereophile: MF heard exactly what this high-power—400Wpc specified, 586W at clipping!—John Curl-designed amp's specs showed: "ultra-wide bandwidth, high-current capability, low, low noise, a high S/N ratio, and a fast slew rate, among many other indicators of outstanding amplifier performance . . . .There was an honesty to the overall tonal and harmonic presentation that transcended technological stereotypes." MF found the overall sound to be powerful, refined, smooth, organized, dynamic, transparent, and rhythmically supple, if a little on the subtly warm and rich side of the sonic spectrum, but decided that this was not at the expense of transient speed and resolution of detail. "Perhaps some listeners will find the JC 1 too refined and perhaps a tad polite, but I didn't." "Rocks for sure," says ST, adding that with the amp driving the Triangle Magellans, he found the "bass firmed up, the sound wasn't strained in any way, and there was an overall sense of ease. Dynamic ease. Listening ease. Just ease. Compared to the Halcros, the Parasound JC 1s brought the soundstage forward. Tonally, the Parasounds were magnificent . . . with no trace of solid-state hardness. And the amps weren't even broken in." "The Parasound JC 1 is one of the finest high-powered solid-state amps I've heard," said ST. "Think of it as a 25W class-A amp that does 400W class-AB when pushed." Matched with the JC 2 preamp, the JC 1s presented even greater holographic detail and transparency. The Parasound Halo JC 1 traded the Moscode 402Au's snappy, vivid tonality and larger soundstage for "quiet precision," clarity, and focus, said WP. The Halo JC 1 traded the Aesthetix Atlas's creamy midrange for greater bottom-end heft and top-end extension, said WP. Compared to the Bryston 7B SST2, the Parasound had deeper bass, tighter images, faster transients, and greater low-level resolution and microdynamic delicacy, said MF. A favorite of JA's, who was equally impressed by how the JC 1 performed on the test bench: "This is excellent measured performance. The Halo JC 1 is not only the best amplifier to come from Parasound, it ranks up there with the best high-end heavyweights," though WP felt that while the Halo JC 1 exhibited grace and delicacy compared with the much more expensive Luxman B-1000f, it lacked some impact, drive, resolution, and detail. Stereophile's—and Sam Tellig's—"Joint Amplification Component" for 2003.
