Power Amplifier Reviews

Back in the days when CRT front projectors roamed the earth, any serious home theater required a separate surround processor and amplifier. In fact, it wasn’t uncommon to find a Tri-Amplisauri from Parasound, Proceed, and others covering those three all-important front channels. Of course, technology has advanced significantly in the past decade. These days, unless you have some very special needs, you can’t go wrong with today’s powerful and reasonably priced one-piece receivers. Many have more amplified channels than Hillary Clinton has pant suits. Rotel makes a number of A/V receivers. I even reviewed one for UltimateAVmag.com a few years ago. But the separates I reviewed here are not simply a case of cutting the baby in half. This here is a new species.

In the world of cars, any make and model will get you where you need to go. Some will get you there faster, and others will get you there in style. However, only a select few exude an air of sophistication and grace.

Founded in early 1972 by Ivor Tiefenbrun, Scottish manufacturer Linn Products has consistently been on the cutting edge of audio development and delivered products that have enamored many audiophiles. Just think of the Linn Sondek LP12 turntable, the Sondek CD12 compact-disc player, or even the Komponent speaker system that Michael Trei reviewed in these pages (in the March 2006 issue). Linn has routinely pushed the boundaries and treaded ahead of the manufacturing pack. Case in point: the Chakra range of amplifiers, which rely on switch-mode power supplies, plus other proprietary developments on the audio-circuit side.

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.

The component that put NAD on the map in the mid 1970s—the 3020 integrated stereo amplifier—didn't look like a giant killer. Finished in an indeterminate shade of grayish-brown and devoid of gee-whiz features, the 3020 nevertheless became one of the best-selling audiophile amplifiers of all time—and not just because it sounded better than anything going for two or three times its humble MSRP. The 3020 had that special something that made it, well, lovable. Over the decades, the engineers squeezed a bit of the 3020's magic into every NAD product, but they've pulled out all the stops with the new Masters Series components. They had to, as the ultimate NADs are competing with the likes of Anthem, Arcam, B&K, and Rotel. They're playing with the big boys now.
