Solid State Power Amp Reviews

When I went to my shelf of Stereophile back issues to find Paul Bolin's seminal">http://www.stereophile.com/solidpoweramps/683">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.

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">http://www.stereophile.com/solidpoweramps/167">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">http://www.stereophile.com/solidpoweramps/905sim">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.

Just in case you didn't know this when you bought the Parasound HCA-3500, it says on the cover of the owner's manual: "Designed in California, USA by John Curl." Described as an "audio design legend," an appellation with which he seems quite uncomfortable, John Curl has certainly been around the audio business longer than most. He's been employed by or has consulted for some of the biggest names in consumer and professional audio—including Harman/Kardon, Ampex, and Mark Levinson—and was the designer of at least two classic products: the Mark Levinson JC-2 preamplifier and his own Vendetta">http://www.stereophile.com/phonopreamps/640">Vendetta Research phono stage, still considered by many people to be the best phono stage ever built.
