Ø Audio Verdande loudspeaker
Full-range speakers are usually at least three-way rather than two-way, for good reasons. Although a three-way crossover network is harder to do right, and there can be phase-coherence issues if the drivers aren't well-matched and well-integrated, a two-way speaker with a woofer big enough to generate room-filling lows is even more difficult.
Abbingdon Music Research PH-77 Phono Equaliser
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.
Acapella High Violoncello II loudspeaker
Stereophile's founder, the late J. Gordon Holt, always had a thing for horn loudspeakers, feeling that these archaic beasts offered a "jump factor" that could never be rivaled by conventional, direct-radiating designs. A horn drastically increases the efficiency with which electrical power is converted into acoustic power, which means that for a given sound-pressure level, a smaller amplifier can be used compared with a direct-radiator, and that all distortions, both electrical and mechanical, can theoretically be much lower. Yet outside of a small circle of enthusiasts, horns never got much of a following in high-end audio, and as high amplifier power became plentiful and relatively cheap, horns largely disappeared from domestic audio use (except in Japan).
Accuphase A-300 monoblock power amplifier
One of the finest chamber music performances I have ever attended took place this past August under far from ideal circumstances. The venue was one-month-old Field Hall in Port Angeles, Washington, a city of fewer than 20,000 people known more for its port and proximity to the Olympic National Forest than for its rich culture. Perhaps that reputation will soon change, because the performers in the concluding concert of the Music on the Strait chamber music festival included its two local founders, violinist James Garlick of the Minnesota Orchestra and violist Richard O'Neill, the newest member of the Takács String Quartet. These excellent musicians, who have been friends since high school, were joined by the superb pianist Jeremy Denk and cellist Ani Aznavoorian. These are world-class musicians who attract eager audiences to New York's 92nd Street Y and Carnegie Hall, London's Wigmore Hall, and other prestigious venues. . .
What was true for that live performance in Field Hall is also true for performances reproduced on audio systems: A system can be less than technically perfect yet still transmit with eloquence every iota of care and feeling that artists and engineers put into recordings. Perfection is not an essential component of musical truth. Inspiration is.
Lest readers think this preamble is intended to suggest some shortcoming in the component under review, the Accuphase A-300 monophonic power amplifier ($51,900/pair), let me reassure you at the outset: Time and again, the A-300, like Jeremy Denk's artistry, inspired a state of wonder. The more I listened to the A-300 monoblocks, the more I wanted to listen. In my too-busy life, every occasion for listening was an occasion indeed, a special event.
Accuphase DP-80L CD player & DC-81L digital processor
$13,000! You could buy two Hyundai Excels for that kind of money. Or one 5-liter Ford Mustang. Or two-thirds of a Saab 900 Turbo. How could the purchase of this Accuphase two-box CD player be justified on any rational grounds? What if it did offer state-of-the-art sound quality? Would it really be 50 times better than a humble Magnavox? Would it even be 4.3 times better than the California Audio Labs Tempest II CD player? And would it approach the sound quality routinely offered from LP by the similarly priced Versa Dynamics 2.0 turntable?Accuphase DP-90 CD transport & DC-91 D/A processor
In 1995, as the compact disc enters its second decade of commercial reality, it's fair to say that the associated hardware has come of age, exorcising at last the digital gremlins of time-base jitter and quantization noise. Digital-processor maturation is particularly evident in the design of the all-critical D/A processor. The simplistic digital circuitry of yesterday has given way to considerable design sophistication that deals directly with jitter and low-level nonlinearities.
Aerial Acoustics 20T V2 loudspeaker
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">http://www.stereophile.com/interviews/467">Michael Kelly, had arranged to compare the speakers reproducing the recorded sound of virtuoso violinist Arturo Delmoni with the real">http://forum.stereophile.com/photopost/showphoto.php/photo/467">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">http://www.stereophile.com/floorloudspeakers/404aerial">wrote about it in April 2004.
Allnic D-5000 DHT D/A processor
There may have been a time when vacuum tubes and microprocessors seemed strange bedfellows. But nowadaysgiven the countless digital processors with tubed output stages, and an even greater number of tubed amps and preamps whose insides are crawling with the latest solid-state deviceswe're more or less used to the idea. Here as elsewhere, hybrids are no big deal.
Analog #246: AudioQuest Niagara 7000 Low-Z Power Noise-Dissipation System
Are you old enough to remember when the wires connecting speakers to even the most expensive and sophisticated electronics were 16-gauge, multistrand lamp cord, and the terminals on speakers and amplifiers were just little screws? Sometimes those screws wouldn't even secure all of the wires' strands, but as long as loose strands from one screw didn't touch loose strands from the other, it was good enough . . . and back against the wall went your bookshelf speakers.
Analog Corner #207: Wave Kinetics NVS Reference turntable & Durand Telos tonearm
The late Jonathan Tinn of Blue Light Audio, importer of darTZeel electronics and a partner in Playback Designs with DSD expert Andreas Koch, loved vinyl. He approached Wave Kinetics' Matt Schuster and proposed that they together produce a turntable. Matt Schuster came up with the Wave Kinetics NVS Reference turntable ($45,000).
