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.

The fireworks are popping, the burgers are grilling, and the bourbon is flowing, which can only mean one thing: It's the end of another workday at the Lewis house. When that day falls early in the month of July, you can bet that some extra contemplation of all things American will be on the itinerary, as well. Let's face it: Is there anything more American than an underdog? I'll bet Ron Fone and Eugene Tang don't think there is, which may be why they decided back in 1998 to start Sherbourn right here in the USA—in Boston, no less. Sure, market size, the economy, and the fact that both men were already working for American companies were undoubtedly the real cause. But, somewhere in the back of their minds, they had to figure that, if a loose confederation of farmers, merchants, and castaways from all over Europe could defeat (or at least outlast) the greatest military power of the time and forge a nation that would quickly become a world superpower, then a small, sharply focused amplifier company just might be able to shoulder in with the big boys and get its piece of the pie.

While Sunfire's Bob Carver isn't quite the household name that Apple's Steve Jobs is, he absolutely qualifies as a bona fide audio legend. Carver's greatest hits range from his early high-power amplifier, the 350-watt-per-channel Phase Linear 700, to Sonic Holography, Bob's virtual-surround generator. Carver also did much to inspire the new breed of super-potent, ultracompact subwoofers with his much-copied Sunfire True. His knack for audio innovation pumped my expectations for a couple of his latest creations, Sunfire's Theater Grand TGP-5 pre/pro and the TGA-5400, a 400-watt-per-channel amplifier.

It’s a fact of modern life. The higher you climb in the high end of anything, the less, at least in one sense, you will get. You will find, I believe, few gargoyles on buildings designed by I.M. Pei, and even fewer rear-seat DVD screens in Paganis.

The Dreadnaught (reviewed in our Oct-ober 2000 issue) was the first power amplifier from Theta Digital, a company previously known for its D/A converters, CD and DVD transports, and surround processors. But it wasn't to be the last. The Dreadnaught II is now a member of a growing family of Theta amplifiers—the premier multichannel design in a line that also includes high-end monoblocks.
