Power Amplifier Reviews

In my student days, I coped with perpetual financial shortfalls in part by moving furniture. After a weekend of toting hide-a-beds and refrigerators to fifth-floor walkups, I would imagine a perfect world in which everything was designed to work with everything else. Not a world of bureaucratic regimentation, but one in which, by common agreement, every sofa would fit into every elevator and every table would slip through every open door.

My curiosity was naturally piqued a few years ago when I heard that Parasound was going upscale with their look. This was a company that had become virtually synonymous with performance plus value, facilitated somewhat by forgoing aesthetic flair, and I wondered where the decision to go uptown with the finish in the Halo line would lead. The first good sign was the Halos' higher price tags. It costs a lot more to make boxes look that good, and this told me that they weren't taking resources away from performance to do so. What ultimately satisfied my curiosity, though, was how good the Halo models sounded. Yet, there are still those who want Parasound performance, have less to spend, and don't mind—or maybe even appreciate—Parasound's rugged, utilitarian old style. The New Classic line is exactly what they're looking for.

On the battlefield of speaker design, I am the triage nurse. I walk into speaker demo rooms at trade shows, my badge sometimes inadvertently turned inward, listen for a moment, and quietly mutter to myself, "This one's a keeper," or, "He's dead, Jim." Or occasionally just, "Hmmm," because good speakers may sound iffy under bad conditions, and I respect the potential buried within an ambiguous first take. But, if my instincts tell me to pursue a review, I whip out a business card and start making arrangements on the spot.

For a country with a population of fewer than 6 million, Denmark has an amazingly high profile when it comes to manufacturers of audio and home theater products. Bang & Olufsen, Dynaudio, Vifa, Peerless, Jamo, Gryphon, Ortofon, Thule, Dali, TacT—the list goes on and on. According to the folks at US importer Sumiko, Primare (pronounced "prime-AIR") has been around since the 1980s, and their products combine outstanding industrial design with an emphasis on sound quality. In the late '90s, the Primare team was joined by Michael Bladelius, well-known for his analog and digital design work for Threshold, Classé, and Pass Labs. Primare products are now manufactured in Sweden, while the head office and design center remain in Denmark.

Emotiva. The name sounds like the latest cure-all marketed by Big Pharma on the evening news programs. (Remember “restless leg?”) It is, in fact the consumer-audio brand of Tennessee’s Jade Designs. And Jade Designs, in turn, is the direct-to-consumer brand founded by a longtime veteran of the rough-and-tumble electronics OEM (original equipment manufacturing) world.

Few audio companies are as closely associated with a single individual as Pass Laboratories is with its founder Nelson Pass, a man who has always blazed his own path when it comes to designing audio gear. Pass founded Threshold Electronics back in the early 1970s, but when he wanted to explore new, simpler circuit topologies in the early 1990s, he created Pass Labs as a way to market his latest creations.

The two integrated amps in the Pass Labs line, the INT-150 and INT-30A, are a good example of his less-than-conventional approach, seeing as both appear to be  identical except for the critical question of output power. Physically the two amps are indistinguishable, with exactly the same functions, weight, dimensions, and even price tag. It's only when you take a peek at the spec sheet that the differences become apparent, with the INT-150 delivering a healthy 150 watts per-channel, while the INT-30A tops out at just one-fifth that amount.

So what gives? Why would anyone buy an inline four when they're offering you the V-12 for the same money?
