Canadian manufacturers enjoy a special relationship with the US market. Though technically their products are "imports," a high level of trade harmony, plus a common continental location, mean that Canadian designs tend to be equably priced in contrast to those exported to the States from overseas.

Talk about going from the ridiculous to the sublime. One day I'm reviewing the $139 Sonic Impact Super T power amplifier, and the next day Krell Industries delivers their $10,000 Evolution 505 SACD/CD player, $15,000 Evolution 202 preamplifier, and their $30,000/pair Evolution 600 monoblocks.

I've been tweaking my weekend multichannel system for years, but with my city system I've kinda faked it. I now realize that I listen more actively to the weekend system, and not only because that's when I have the time for it—the sound of that system is simply more engaging and psychologically immersive. So, with the growth of my library of SACD and DVD-Audio recordings to almost half the size of my CD collection, I told my wife that it was time to transform of "our" city stereo rig into a full-blown multichannel system.

Eleven years ago, Threshold Corporation entered the high-end audio market with the first amplifier ever to use sliding bias (footnote 1) in its output stages. Some 10 years later, Threshold spawned another innovation: their so-called Stasis circuitry, which yielded the S-series amplifiers. The SA-1 and its lower-powered sister SA-2 are the latest from Threshold, and are the first Threshold amps to abandon sliding bias for straight class-A operation. Both use the Stasis circuit.

Best known for its omnidirectional loudspeakers, the German manufacturer mbl also produces three complete lines of high-performance electronics that, despite being large and built to jewel-like perfection, are sometimes lost in the shadow cast by the dramatic-looking—and -sounding—Radialstrahler 101E, which I reviewed in October 2004.

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.

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.

When I went to my shelf of Stereophile back issues to find Paul Bolin's seminal review of the Halcro dm58, I was shocked to find myself leafing further and further back—through not only 2004 but 2003 as well, all the way back to October 2002 (Vol.25 No.10). It doesn't seem possible that it's been almost four years since Halcro exploded onto our radar screens, the dm58 emblazoned on that issue's cover alongside the banner headline "THE BEST AMPLIFIER EVER!"

Where does one start with the Moscode 401HR? With its design, which marries a tube driver stage to a MOSFET power output? Or perhaps with its designer, George Kaye, who refined Julius Futterman's OTL amplifier circuits before creating New York Audio Labs' original hybrid amplifier, the Moscode 300, in 1984?

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.

Within a few years of entering the US market, Australian audio manufacturer Bruce Halcro Candy cemented his place in audio history by designing a amplifier that Paul Bolin said (in the October 2002 Stereophile) "could well justify the creation of a 'Class A+' amplifier category in 'Recommended Components'," and the low distortion characteristics of which prompted editor John Atkinson, a man who has elevated the craft of understatement to a high art, to reach for the word astonishing. That was the Halcro dm58 monoblock ($29,990/pair), which has only recently been superseded by the Halcro dm78.

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.

Lord Acton said, famously, that power corrupts and absolute power corrupts absolutely. If there ever were an amplifier to test that maxim's applicability to audiophiles, it is surely the Chord SPM 14000 Ultimate Monoblock. Priced no less than $75,000/pair, the SPM 14000 is rated to produce power as do very few other amplifiers on the planet: it is very conservatively rated at 1kW into an 8 ohm load, 2kW into 4 ohms, and "will easily exceed" 2800W (give or take a few watts) into 2 ohms.

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...
