If you're not in the "club," high-end audio might look like a bastion of elitist snobs and the idle rich, so it may come as a shock to note that some of high-end audio's greatest engineers started out in rock and roll. Take John Curl, in the early 1970s he worked his magic on the Grateful Dead's concert and recording sound systems and later kept the Jefferson Airplane aloft. That was just before he tackled film sound in Hollywood. All of that led to collaborations with high-end pioneer Mark Levinson; together they raised the stakes, considerably, with the JC 2 stereo preamplifier in 1974.

It didn't matter that the JC 2 was two or three times more expensive than any other component in the nascent high-end market; a lot of folks lucky enough to hear it and afford it bought it. The JC 2 had that effect on people. Curl and Levinson soon parted ways and over the next few years Curl designed a long run of cutting edge electronics for other companies. Levinson eventually departed the company that bears his name, and his old company now designs car audio systems for Lexus. High-end is in the big time now.

When I heard that Curl had finished work on an all-new Halo Series JC 2 stereo preamplifier for Parasound I had to check it out (it's like hearing that Carroll Shelby just built a new AC Cobra). Better yet, for this review Parasound sent along a pair of the matching Halo Series JC 1, 400 watt mono power amplifiers. I reviewed the all-new JC 1 & JC 2 combination for Home Entertainment magazine, you can read the review here.

The JC 1 is a seriously powerful amplifier, its output stage employs nine pairs of high-current bipolar transistors with massive heat sinks to insure long-term reliability. Each amplifier can deliver 400 watts to 8 ohm rated speakers, and 800 watts to 4 ohm models, and if your speakers ever dip as low as 2 ohms, the JC 1 will happily serve 1,200 watts! The JC 1 sounds potent, even when listened to at merely moderately loud levels, and maintains its composure at lease breaking, call-the-cops volume.

Stereophile magazine's excellent coverage of the high-end audio scene at CES '08 at the Venetian Hotel has kept me on the edge of my seat since Monday. So many great new products, from old and new companies say a lot about the thriving, worldwide audiophile market. I've picked five products to show you, but Stereophile's site has dozens of really cool sightings.

The CD may be on its way out, but vinyl is going strong. Revolver's new Replay turntable, $3499, looks killer.

Between projectionist gigs he worked as a high-end audio salesman for sixteen years, and produced records for an audiophile label. Oh, and one more thing, nothing annoys Steve more than being confused with the other Steve Guttenberg, the washed-up Police Academy actor.
