Man, you've got to watch out for those preconceived notions—they'll kill you every time. For the last several years I've seen Plinius amplifiers at hi-fi shows and—even though I didn't know the first thing about the company or its products—figured that I knew what they were all about. Spotting their brawny façades festooned with feathery heatsinks, I smugly assured myself that they were some kind of antipodean pretender to the muscle-amp throne—Krell or Threshold wannabes.

Nowadays, when most people think of New Zealand, the first things that probably come to mind are the film trilogy The Lord of the Rings, its director, Peter Jackson, or sheep. Certainly, LOTR was a great achievement in film history and, as its auteur, Jackson reaped no small fame for his efforts, as well as multiple Academy Awards and several krillion dollars. The country is also well known as a place where sheep outnumber humans by something like 12 to 1. However, New Zealand is also the source of some very fine audio equipment; both Perreaux and Plinius are proudly headquartered in beautiful, serene, friendly Kiwiland.

When most of us think about the folks who populate the high-end audio industry, we tend to conjure up the designers—the names above the titles, as it were. Or, in many cases, the names that are the titles: Richard Vandersteen, Jim Thiel, Bill Conrad and Lew Johnson, Mike Creek, to name just a few.

Several issues back, I mentioned a major "new wave" of power amplifiers coming along: the Adcom 555, the New York Audio Labs transistor-tube hybrids, and the latest Krells, for example. They demonstrate that major audible improvements are still possible in something as well-explored as the power amplifier. Not only that, some of these products demonstrate that superior performance can be combined with relatively low price.

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

This is something we don't see too often: an entirely new approach to power amplifier design. As Quad points out in its literature for the 405, class-A operation of transistors provides the lowest distortion, but drastically limits the amount of power an output transistor can deliver without overheating. (Most transistor amps use class-AB output operation, in which each of a pair of power transistors handles part of each signal cycle and shuts down during the other part. Imperfect synchronism between the two halves causes the familiar "crossover distortion," which accounts for most solid-state sound. In class-A operation, each output transistor draws current though the entirety of each signal cycle, eliminating the crossover transition but doubling the amount of time current is drawn, and thus tending to cause the transistor to heat up more.)

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.

An amplifier producing nearly 400Wpc, weighing close to 100 lbs...from Rotel, of all people? Don't they know their place in the audio world? Next thing you know, Krell will start making integrated amplifiers! Oops—Krell is making integrated amplifiers...

Okay, here you are: You're a Real World music lover trying to sling together a Real World hi-fi rig. You gotcha budget-king NAD/Rotel/JVC/Pioneer CD player, your SOTA Comet/Sumiko Blue Point analog rig, and your cool-man NHT/PSB/Definitive Technology entry-level speakers. Hell, you've even gone out and bought a few pairs of Kimber PBJ interconnects to hook it all up. This ain't no dog and pony show—you want that High-End High, not just some cheap'n'cheerful, low-rez rig to stick in the rumpus room so the kids can listen to that weak-ass, faux-grunge, watered-down Hendrix-howl that modern-day wimp-boys like Pearl Jam dish out to anyone under 30 who doesn't know any better.

As a reviewer who has focused on seeking out high-quality audiophile gear for cost-constrained readers, I'm embarrassed to say that the flagship RB-991 stereo amplifier is the first Rotel product I've had in my house. (To be fair to myself, this 38-year-old family-owned company did not develop a large US market presence until this last decade.)

In the September 2005 issue (Vol.28 No.9), I reviewed Simaudio's first reference-quality power amplifier: the 1000W, 220-lb Moon Rock monoblock ($37,000/pair). At the time, the Rock was a dramatic departure for Simaudio, then primarily known as a maker of midpriced gear that was good for the money. I found a lot to like about the Rock, concluding that while it wasn't quite up to the standard of the best superamps of the time, it was very good—and, for Simaudio, an admirable first shot at the state of the art.

When I reviewed the Moon Evolution P-7 preamplifier ($6900) from Canadian manufacturer Simaudio in March 2009, I was impressed by the qualities of both the audio engineering and the sound. It was a no-brainer, therefore, to follow that report with a review of the matching power amplifier, the Moon Evolution W-7. In March 2006 Kalman Rubinson reviewed Simaudio's Moon Evolution W-8, which offered at least 250Wpc into 8 ohms (I measured 310Wpc at clipping). The W-7 looks identical to the W-8, but is 10 lbs lighter, offers 150Wpc into 8 ohms, and retails for $8900 compared with the W-8's $13,500.

The W-8 ($10,200) is the first of Simaudio's Moon series to incorporate the new Evolution cosmetics and new circuitry. I loved its predecessor, the Moon W-5, which was one of the first power amplifiers I reviewed for Stereophile (March 1999, Vol.22 No.3). I also loved the "new and improved" W-5 when I wrote about in the May 2001 issue. In the September 2005 issue, Brian Damkroger praised Simaudio's monstrous Moon Rock monoblock, a contemporary of the Moon Evolution W-8 stereo amp.

I first saw and heard SimAudio's Moon amp and preamp at WCES two years back, and something about their aesthetics appealed to me: Canadian ruggedness coupled with a decidedly French panache. I remember that those attributes also characterized the demo's sound, although I can't recall the speakers or the sources involved. At succeeding shows, it gradually dawned on me that the Moon components were the fixed elements in a succession of impressive demos.

For years, I thought of Simaudio gear as good-sounding, attractive, and modestly priced, often describing it to friends as "really good for the money." The $5500 Moon Eclipse CD player, which I reviewed in our April 2001 and April 2003 issues, stretched the "modestly priced" descriptor a bit, but its sound was still, I thought, really good for what it cost, and I adopted it as a reference. Simaudio expanded the Moon series and eventually discontinued its older, less expensive Celeste brand, but, I thought, its products could still be described as "really good for the money."
