Solid State Power Amp Reviews

How did Michael Jordan, talented as he was at the peak of his powers, always manage to impose his will on his teammates to push them to victory when it counted most? What made Sandy Koufax able to elevate his pitching to a superhuman level when the stakes were highest? A knowledgeable, hardcore sports fan can watch the performance of two players with nearly identical statistics and, after not too long, tell you which one is merely very good and which one is great. What makes a star are intangibles—those qualities you can't quantify or analyze, but can't help but recognize when you're in their presence.

Thirty years ago, the upstart audio company NAD revolutionized the manufacturing of consumer-electronics components by "internationalizing" the process. Instead of physically making products, NAD hired a project team in one location to design a product that was then built at a sub-contracted factory located elsewhere. The arrangement allowed NAD to go into business with relatively little capital outlay and low overhead. Other companies have since copied this ingenious business model, and, as transportation and communication have improved, doing so has become easier and more efficient. It has brought prices down and quality up—mostly in the low and middle segments of the high-end audio and video markets.

Modern hi-fi is little more than a way of getting electricity to pretend that it's music. Of course, good source components remain all-important, and even if loudspeakers are imperfect, most of us can find one or two that suit our tastes, if not our rooms and the rest of our gear.

I have a way of grating on people's nerves. Ask Marina, my wife. She calls it my "mean streak."

Revolutionary is a word that's tossed around all too lightly in the world of audio. The understandable impulse to tout every new development as a quantum leap forward in sound reproduction has made it difficult to sort out the evolutionary from the truly groundbreaking. And there's not that much left to do in amplifier design that is worthy of being described as "revolutionary," or so it seems. Vacuum-tube circuitry has been thoroughly understood since the late 1940s, and 40 years of development of solid-state has rendered it, in its finest implementations, a worthy competitor and alternative to the venerable tube.

As we all know, it's the sound that counts. However, good looks enhance pride of ownership, and Theta Digital's class-AB, 400W Citadel is as handsome a monoblock as these jaded eyes have laid eyes on.

What could be easier to review than a power amplifier? No features or functions aside from inputs, outputs, and a power switch. So when Jonathan Scull asked if I could help out by taking on the Rotel RB 1080, which another reviewer hadn't been able to get to, I accepted the assignment. Before I could click my heels and say "FedEx!" twice, Rotel's 200Wpc RB 1080 had appeared.
