Boulder Amplifiers 1008 phono preamplifier

Why bother with three phono preamps most of us can't afford? For the same reason the enthusiast automobile magazines cover the newest Ferraris and Lamborghinis: just reading about them is fun.

Audacious AudioTonearm Reviews
Spiral Groove Centroid tonearm
Brian Damkroger  |  Jun 16, 2010  | 
Spiral Groove's new Centroid tonearm ($6000) arrived just a few days before press time, so it would be risky to say anything definitive about it. But I will take that risk: using the system described in my review of the SG2 turntable, this may be the best tonearm I've heard. Its sound is different in ways that will open people's ears, and I predict that it will affect the design of every tonearm from now on. The Centroid's design deserves and will await full coverage in its own review, but here are the basics: It's a fluid-damped unipivot design unlike any other that gives the user fine adjustment of all relevant parameters.

High-end audio exists at the intersection of art and science. Either discipline can produce a good product, but it takes both to create the very best. The Sonic Frontiers gear I auditioned many years ago, for example, was technically sound, nicely built, and sounded good—just never as sublime as products from, say, Audio Research or VTL. On the other hand, an experienced, insightful designer such as Quicksilver's Michael Sanders can create wonderful products from humble circuits and parts, but be ultimately limited by the underlying technology. But when brilliant design, uncompromised execution, long experience, and artistry all come together, the results can be staggering.

Musical Fidelity AMS Primo line preamplifier
Michael Fremer  |  May 15, 2010  | 
Musical Fidelity's Tri-Vista kWP, introduced in 2003, was an impressive, high-tech, "statement" audiophile preamplifier. Its outboard power supply weighed almost 56 lbs—more than most power amplifiers—and its hybrid circuitry included miniature military-grade vacuum tubes. As I said in my review of it in the January 2004 Stereophile, the kWP's chassis and innards were overbuilt, the measured performance impressive, and any sonic signature imposed on the signal was subtle and, essentially, inconsequential.

JBL Synthesis 1400 Array BG loudspeaker
Larry Greenhill  |  May 10, 2010  | 
JBL was founded 60 years ago, by Jim Lansing. Its history has been amply detailed in the book The JBL Story: 60 Years of Audio Innovation, by the late John Eargle's (JBL Professional, 2006). Although it is primarily known for its pro-audio loudspeakers, the Californian company has offered a steady stream of high-performance domestic loudspeakers to the home market, including the 1971 Paragon, the L100 bookshelf speaker, and the JBL 250Ti floorstander, all of which remained in JBL's catalog for 20 years. In 1990, JBL produced the Project K2 S9500 flagship speaker for the Japanese high-end market. The K2 Project culminated in the $60,000/pair DD55000 Everest system, with its cross-firing asymmetric horns, and the subject of this review, the Synthesis 1400 Array BG, was a spin-off from the K2 project. It features horn-loaded midrange and tweeters to attain a flat response out to a claimed 48kHz.

Vandersteen Model Seven loudspeaker
Michael Fremer  |  Mar 18, 2010  | 
It's difficult to believe that the former top model of Vandersteen Audio's line of loudspeakers, the Model 5, has been in production in one form or another since 1997. Time passes quickly when you're having fun. Like all Vandersteen speakers, the 5 was and remains a good value and performance proposition. For all the 5's high technology and excellent performance both measured and audible, its price now starts at under $20,000/pair (up from about $10,000/pair when the 5 was introduced in 1997), including a built-in, proprietary powered subwoofer in each cabinet, and a sophisticated equalization system for room compensation.

Oracle Delphi Mk.VI turntable
Michael Fremer  |  Dec 27, 2010  |  First Published: Mar 01, 2010  | 
Thirty years have not diminished the beauty and elegance of Oracle's Delphi turntable. In my opinion, it still ranks among the best-looking turntables ever made. I bought an original Mk.I, used, in 1982, and very positively reviewed the Delphi Mk.V in the December 1997 Stereophile.

In its three decades the Delphi has undergone many upgrades both technical and aesthetic. Not surprisingly, so has the price. The Mk.II Delphi sold for $1250 in 1986; the Delphi Mk.VI with Turbo power supply and dedicated power cord now sells for $8500, which, in today's market, I think is reasonable for what you get. The review sample came with an Oracle/SME 345 tonearm ($3100) and a Benz-Micro Thalia high-output MC cartridge ($1700), for a total cost of $13,300—or $11,600 for just 'table and arm.

Playback Designs MPS-5 SACD/CD player
Michael Fremer  |  Feb 17, 2010  | 
Playback Designs was founded less than three years ago. However, with the release in 2008 of its MPS-5 Music Playback System—a slim, full-featured SACD/CD player and DAC that costs $15,000 and is built in the US—the company has since established itself as a significant player in high-performance digital audio.

dCS Puccini SACD playback system
John Atkinson  |  Dec 14, 2009  | 
It's now 10 years since the launch of the two high-resolution audio disc formats, SACD and DVD-Audio. Yet, perhaps partly because both were hobbled in various ways to please the record industry, perhaps partly because too many supposed hi-rez releases sounded no better than CD, and perhaps partly because record retailers weren't sure how to display the formats to their best advantage, neither took off in any substantive way. DVD-A disappeared, and SACD survived only as a niche format for high-quality classical releases in both two- and multichannel forms. As we got deeper into the same decade, digital technology, despite various sparks and flashes, went into the doldrums. Mainstream digital technology was increasingly concerned with squashing the music into fewer and more portable bits, not with increased sound quality. Even the concept of "CD sound quality" began to seem an unattainable goal, as MP3 files became the dominant music carrier.

Aerial Acoustics 20T V2 loudspeaker
John Atkinson  |  Nov 13, 2009  | 
It was an audacious demonstration. For the launch of Aerial's 20T loudspeaker at the end of 2002, Aerial's head honcho and designer, Michael Kelly, had arranged to compare the speakers reproducing the recorded sound of virtuoso violinist Arturo Delmoni with the real thing. The setting was the ornate dining room of one of Newport, Rhode Island's many mansions, and, given the inevitable differences—due to the facts that a violin has a very different radiation pattern from a loudspeaker and thus excites the room differently, and that the recording inevitably gives the listener a double dose of the room's acoustic—the demo was successful. There was much subsequent argy-bargying between Stereophile's reviewers about who would review the Aerial 20T, but it was Michael Fremer who eventually wrote about it in April 2004.

Wilson Audio Specialties MAXX Series 3 loudspeaker
Michael Fremer  |  Sep 14, 2009  | 
Though taller, narrower, deeper, more gracefully sculpted, and even more mantis-like than the MAXX Series 2 that I reviewed in the August 2005 Stereophile, at first glance the Wilson Audio Specialties MAXX Series 3 seems little more than a minor reworking of its predecessor with a major increase in price: from $44,900 to $68,000 per pair. But first looks can be deceiving. Take a closer, longer gaze—or, better yet, spend some time listening (especially if you've spent time with the MAXX 2)—and you'll quickly realize that while the familiar Wilson design concepts remain in play, the MAXX 3 is far more than a minor reworking of an older model.

darTZeel CTH-8550 integrated amplifier
Wes Phillips  |  Aug 24, 2009  | 
As the 2009 Consumer Electronics Show neared its end, I wandered into Blue Light Audio's room, which was dominated by the innards of darTZeel's new NHB-458 monoblocks—think of a 3D "exploded" diagram and you'll be on target. So impressive was that display of brute engineering that I almost didn't notice the amplifier that was actually making the music: the CTH-8550 integrated ($20,300).

Is anyone in this economy shopping for a four-box, rack-swallowing, two-channel SACD/CD player contending for the state of the art and costing $79,996? dCS is betting that its Scarlatti will attract a small crowd of those wealthy music enthusiasts who, in any economy, reliably pony up for the best. For the rest of us, the Scarlatti will be a spectator sport.

Avantgarde Acoustic Uno Nano loudspeaker
Robert Deutsch  |  Jul 25, 2009  | 
A compact horn loudspeaker. Isn't that an oxymoron, like jumbo shrimp, or military intelligence? From such venerable speakers as the half century-old Altec Voice of the Theater and the Klipschorn, as well as more modern examples like the Avantgarde Acoustic Trio, horns have always been big. The original Avantgarde Uno was the smallest speaker in Avantgarde's line, but it was still visually imposing, with a big horn midrange on top, a horn tweeter below that, and a powered sealed-box subwoofer at the bottom. (I reviewed the Uno 2.0 in Stereophile in August 2000, Vol.23 No.8, and the Uno 3.0 in August 2002, Vol.25 No.8.) The Uno and its siblings, the Duo and Trio, are perhaps the antithesis of the in-wall loudspeakers beloved by interior designers. These speakers do not fade into the background—not visually or sonically.
